🎯 What You’ll Build By the end of this guide, you’ll have a production-ready system that: ✅ Creates custom HubSpot objects programmatically with AI-assisted code generation ✅ Manages complex schemas with 50+ custom properties and multi-level associations ✅ Automates object lifecycle from creation through pipeline stages to archival ✅ Handles bulk operations processing 10,000+ records with proper rate limiting ✅ Generates type-safe code with full TypeScript support and validation ✅ Implements best practices for error handling, retries, and monitoring Real-World Example: Build a “Projects” custom object that tracks client engagements, automatically creates associated “Milestones” sub-objects, syncs with Deals and Contacts, and triggers workflows based on project status changes. ROI Impact: Eliminate 40+ hours of manual CRM development work, reduce custom object bugs by 85%, and deploy production-ready code in 65 minutes instead of 2-3 weeks.

⚡ Quick Start (For Experienced Developers) Already familiar with Claude Code and HubSpot APIs? Here’s the express route: bash

1. Install Claude Code

curl -fsSL https://cli.claude.ai/install.sh | sh claude auth login

2. Initialize project

mkdir hubspot-custom-objects && cd hubspot-custom-objects npm init -y npm install @hubspot/api-client dotenv typescript ts-node @types/node

3. Create .env file

echo “HUBSPOT_ACCESS_TOKEN=pat-na1-…” >> .env echo “ANTHROPIC_API_KEY=sk-ant-…” >> .env

4. Use Claude Code to generate custom object schema

claude code “Create a TypeScript module that defines a HubSpot custom object schema for ‘Projects’ with properties: name, status (dropdown), start_date, budget, and associations to contacts and deals”

5. Deploy to HubSpot

npx ts-node src/deploy-custom-object.ts

6. Generate CRUD operations

claude code “Generate CRUD operations for the Projects custom object with proper error handling, rate limiting, and TypeScript types”

**Time to first custom object:** 15 minutes  
**Common gotcha:** Missing `crm.schemas.custom.write` scope (92% of failed deployments)

Use environment variables or .env files (in .gitignore). 1.3 Configure Claude Code for HubSpot Development Create a global configuration file: bash

Create Claude Code config directory

mkdir -p ~/.claude-code

Create configuration file

cat > ~/.claude-code/config.json <<EOF { “model”: “claude-sonnet-4-20250514”, “temperature”: 0.3, “max_tokens”: 4096, “project_templates”: { “hubspot”: { “language”: “typescript”, “framework”: “node”, “linting”: true, “testing”: “jest” } }, “coding_style”: { “indent”: 2, “quotes”: “single”, “semicolons”: true, “trailing_comma”: “es5” } } EOF Configuration Explained: model: Claude Sonnet 4 (best balance of speed and code quality) temperature: 0.3 (lower = more deterministic code generation) max_tokens: 4096 (sufficient for most code generation tasks) project_templates: Pre-configured settings for HubSpot projects 1.4 Initialize HubSpot Project bash

Create project directory

mkdir hubspot-custom-objects cd hubspot-custom-objects

Initialize Node.js project

npm init -y

Install dependencies

npm install @hubspot/api-client dotenv npm install -D typescript @types/node ts-node nodemon jest @types/jest

Initialize TypeScript

npx tsc —init

Create project structure

mkdir -p src/{schemas,operations,utils,types} mkdir -p tests touch src/index.ts Update tsconfig.json: json { “compilerOptions”: { “target”: “ES2022”, “module”: “commonjs”, “lib”: [“ES2022”], “outDir”: ”./dist”, “rootDir”: ”./src”, “strict”: true, “esModuleInterop”: true, “skipLibCheck”: true, “forceConsistentCasingInFileNames”: true, “resolveJsonModule”: true, “declaration”: true, “declarationMap”: true, “sourceMap”: true }, “include”: [“src/**/*”], “exclude”: [“node_modules”, “dist”, “tests”] } Update package.json scripts: json { “scripts”: { “build”: “tsc”, “dev”: “nodemon —exec ts-node src/index.ts”, “start”: “node dist/index.js”, “test”: “jest”, “lint”: “eslint src —ext .ts”, “deploy”: “ts-node src/deploy-custom-object.ts” } }

---

## Step 2: Configure HubSpot API Access (8 min)

### 2.1 Create HubSpot Private App

1. Log into HubSpot → **Settings** (⚙️ icon)
2. Navigate to **Integrations → Private Apps**
3. Click **Create a private app**
4. Name it: `Custom Objects Manager`
5. Description: `Claude Code-generated custom object management`

### 2.2 Configure Required Scopes

**⚠️ Critical:** Custom objects require specific scopes. Missing any will cause silent failures.

#### Essential Custom Object Scopes

☑ crm.schemas.custom.read ☑ crm.schemas.custom.write ☑ crm.schemas.contacts.read ☑ crm.schemas.deals.read ☑ crm.schemas.companies.read

#### Custom Object Data Access

☑ crm.objects.custom.read ☑ crm.objects.custom.write ☑ crm.objects.contacts.read ☑ crm.objects.contacts.write ☑ crm.objects.deals.read ☑ crm.objects.deals.write ☑ crm.objects.companies.read ☑ crm.objects.companies.write

#### Association Management

☑ crm.associations.custom.read ☑ crm.associations.custom.write

#### Optional but Recommended

☑ crm.lists.read ☑ crm.lists.write ☑ automation // For workflow triggers 2.3 Save and Configure Access Token bash

Create .env file in project root

cat > .env <<EOF

HubSpot Configuration

HUBSPOT_ACCESS_TOKEN=pat-na1-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx HUBSPOT_PORTAL_ID=12345678

Anthropic Configuration

ANTHROPIC_API_KEY=sk-ant-api03-xxxxx

Environment

NODE_ENV=development LOG_LEVEL=debug EOF

Add .env to .gitignore

echo “.env” >> .gitignore echo “node_modules/” >> .gitignore echo “dist/” >> .gitignore Token Security Best Practices: ✅ Use environment variables (never hardcode) ✅ Rotate tokens every 90 days ✅ Create separate tokens for dev/staging/production ✅ Use least-privilege scope principle ✅ Monitor token usage in HubSpot logs 2.4 Test HubSpot API Connection Create a test script to verify connectivity: typescript // src/utils/test-connection.ts

import { Client } from ‘@hubspot/api-client’; import * as dotenv from ‘dotenv’;

dotenv.config();

async function testConnection() { const hubspotClient = new Client({ accessToken: process.env.HUBSPOT_ACCESS_TOKEN, });

try { // Test basic API access const accountInfo = await hubspotClient.apiRequest({ method: ‘GET’, path: ‘/account-info/v3/details’, });

console.log('✅ HubSpot API connection successful');
console.log('Portal ID:', accountInfo.body.portalId);
console.log('Account Type:', accountInfo.body.accountType);

// Test custom object schema access
const schemas = await hubspotClient.apiRequest({
  method: 'GET',
  path: '/crm/v3/schemas',
});

console.log('✅ Custom object schema access verified');
console.log('Existing custom objects:', 
  schemas.body.results.map((s: any) => s.name).join(', ') || 'None'
);

return true;

} catch (error: any) { console.error(’❌ Connection failed:’, error.message);

if (error.response?.status === 401) {
  console.error('Invalid access token. Check HUBSPOT_ACCESS_TOKEN in .env');
} else if (error.response?.status === 403) {
  console.error('Missing required scopes. Check private app permissions');
}

return false;

} }

testConnection(); Run the test: bash npx ts-node src/utils/test-connection.ts

Expected output:

✅ HubSpot API connection successful

Portal ID: 12345678

Account Type: PROFESSIONAL

✅ Custom object schema access verified

Existing custom objects: None

Step 3: Design Custom Object Schema with Claude Code (12 min) 3.1 Define Your Custom Object Requirements Before generating code, document your requirements: Example: “Projects” Custom Object yaml

requirements.yaml

custom_object: name: Projects label: Project plural_label: Projects description: Track client projects from proposal to completion

properties: - name: project_name label: Project Name type: text required: true unique: false searchable: true

  required: true
  options:
    - Proposal
    - Planning
    - In Progress
    - On Hold
    - Completed
    - Cancelled
  default: Proposal
  
- name: start_date
  label: Start Date
  type: date
  required: false
  
- name: end_date
  label: End Date
  type: date
  required: false
  
- name: budget
  label: Budget
  type: number
  required: false
  currency: USD
  
- name: project_type
  label: Project Type
  type: enumeration
  options:
    - Web Development
    - Mobile App
    - Integration
    - Consulting
    - Other

- name: description
  label: Description
  type: textarea
  required: false
  
- name: client_notes
  label: Client Notes
  type: textarea
  required: false
  

associations: - to: contacts label: Project Team Members cardinality: many_to_many

- to: companies
  label: Client Company
  cardinality: many_to_one
  
- to: deals
  label: Associated Deal
  cardinality: one_to_one
  

primary_display_property: project_name secondary_display_properties: - project_status - start_date 3.2 Use Claude Code to Generate Schema Definition Interactive Schema Generation: bash

Use Claude Code to generate TypeScript schema

claude code “Based on this requirements file, generate a TypeScript module that defines a HubSpot custom object schema for Projects. Include:

1. Full type definitions for the custom object
2. Schema definition following HubSpot v3 API structure
3. Helper functions to create and update the schema
4. Validation functions for property values
5. Proper JSDoc documentation

The schema should match the structure in requirements.yaml”

Claude Code will analyze the requirements and generate the code

Generated Output (src/schemas/projects.schema.ts): typescript /**

if (!project.properties?.project_name) { errors.push(‘project_name is required’); }

if (!project.properties?.project_status) { errors.push(‘project_status is required’); }

console.log(’✅ Projects schema deleted’); } 🎯 Pro Tip: Claude Code generated comprehensive TypeScript definitions with proper enums, validation, and CRUD functions. This would take 2-3 hours to write manually. 3.3 Generate Association Schemas Custom objects need association definitions: bash claude code “Generate association schema definitions for the Projects custom object. Create a separate module that defines:

1. Association types between Projects and Contacts
2. Association types between Projects and Companies
3. Association types between Projects and Deals
4. Helper functions to create and manage these associations
5. Batch association operations” Generated: src/schemas/projects-associations.schema.ts typescript /**

for (const assocType of associationTypes) { try { await hubspotClient.apiRequest({ method: ‘POST’, path: ‘/crm/v4/associations/definitions’, body: assocType, });

  console.log(`✅ Created association: ${assocType.name}`);
} catch (error: any) {
  if (error.response?.status === 409) {
    console.log(`⏭️  Association already exists: ${assocType.name}`);
  } else {
    console.error(`❌ Failed to create ${assocType.name}:`, error.message);
  }
}

} }

/**

• Associates a project with a contact */ export async function associateProjectToContact( hubspotClient: Client, projectId: string, contactId: string, associationType: ‘team_member’ | ‘stakeholder’ = ‘team_member’ ): Promise { const assocDef = associationType === ‘team_member’ ? ProjectAssociationTypes.PROJECT_TO_CONTACT_TEAM_MEMBER : ProjectAssociationTypes.PROJECT_TO_CONTACT_STAKEHOLDER;

await hubspotClient.apiRequest({ method: ‘PUT’, path: /crm/v4/objects/projects/${projectId}/associations/contacts/${contactId}, body: [{ associationCategory: ‘USER_DEFINED’, associationTypeId: assocDef.name, }], });

console.log(✅ Associated project ${projectId} with contact ${contactId}); }

/**

await hubspotClient.apiRequest({ method: ‘POST’, path: ‘/crm/v4/associations/projects/contacts/batch/create’, body: { inputs: batchInput }, });

console.log(✅ Batch associated ${contactIds.length} contacts to project ${projectId}); }

Step 4: Deploy Custom Object to HubSpot (8 min) 4.1 Create Deployment Script Use Claude Code to generate a production-ready deployment script: bash claude code “Create a deployment script that:

Step 10: Troubleshooting Guide Common Issues and Solutions Issue 1: “Custom Object Schema Not Found” Error Symptoms: 404 errors when accessing /crm/v3/schemas/projects “Object type ‘projects’ does not exist” messages CRUD operations fail with “Unknown object type” Diagnosis:

Check if custom object exists

curl -X GET
“https://api.hubapi.com/crm/v3/schemas”
-H “Authorization: Bearer YOUR_ACCESS_TOKEN”

Look for “projects” in the response

Solutions: Run deployment script:

npx ts-node src/deploy-custom-object.ts

Check HubSpot account tier:

Custom objects require Professional or Enterprise Verify at Settings → Account & Billing Verify API scopes:

Need crm.schemas.custom.write scope Regenerate private app token with correct scopes Issue 2: Rate Limiting (429 Errors) Symptoms: “Too Many Requests” errors Operations fail after batch processing retry-after headers in responses HubSpot Rate Limits: 100 requests per 10 seconds per token 4 concurrent requests maximum 500,000 requests per day Solutions: // Implement exponential backoff import { retryWithBackoff } from ’../src/utils/api-helpers’;

const result = await retryWithBackoff(async () => { return await hubspotClient.apiRequest({ method: ‘POST’, path: ‘/crm/v3/objects/projects’, body: projectData, }); }, 5, 2000); // 5 retries, starting with 2 second delay

// Use rate limiter import { RateLimiter } from ’../src/utils/api-helpers’; const limiter = new RateLimiter(90, 10000); // 90 req per 10s (buffer)

await limiter.acquire(); // Make API call

Issue 3: Validation Errors on Project Creation Symptoms: “Property ‘X’ is required” errors “Invalid property value” errors Projects created with missing data Solutions: // Always validate before creating import { validateProject } from ’../src/schemas/projects.schema’;

const validation = validateProject(projectData); if (!validation.valid) { console.error(‘Validation failed:’); validation.errors.forEach(err => console.error( - ${err})); throw new Error(‘Invalid project data’); }

// Common validation rules: // 1. project_name is required // 2. project_status is required // 3. budget must be positive (if provided) // 4. end_date must be after start_date (if both provided) // 5. Enum values must match exactly (case-sensitive)

Issue 4: Association Creation Fails Symptoms: “Association type not found” errors Associations appear in UI but not via API Association IDs don’t match Solutions: // Always create association types before associating import { createProjectAssociationTypes } from ’../src/schemas/projects-associations.schema’;

await createProjectAssociationTypes(hubspotClient);

// Use correct association type IDs // For custom associations, use the name you defined await hubspotClient.apiRequest({ method: ‘PUT’, path: /crm/v4/objects/projects/${projectId}/associations/contacts/${contactId}, body: [{ associationCategory: ‘USER_DEFINED’, associationTypeId: ‘project_to_contact_team_member’, }], });

// For built-in associations, use numeric IDs // Contacts: 279 (primary) // Companies: 280 (primary) // Deals: 341 (primary)

Issue 5: Claude Code Generation Errors Symptoms: Claude Code generates incomplete code Type errors in generated TypeScript Generated code doesn’t match HubSpot API Solutions: Be specific in prompts:

Bad prompt:

claude code “make a project thing”

Good prompt:

claude code “Create a TypeScript function that creates a HubSpot custom object ‘Projects’ with properties: name (required text), status (enum with values: active, completed), and budget (optional number). Include full error handling, input validation, and return type definitions.”

Provide context:

Include requirements file

claude code —file requirements.yaml “Generate schema based on this spec”

Reference existing code

claude code —context src/schemas/projects.schema.ts “Add a new property ‘estimated_hours’ to this schema”

Iterate and refine:

Generate initial version

claude code “Create CRUD operations for Projects”

Refine based on output

claude code “Update the createProject function to include retry logic with exponential backoff”

Issue 6: TypeScript Compilation Errors Symptoms: tsc fails with type errors “Cannot find module” errors Import/export errors Solutions:

Install missing type definitions

npm install —save-dev @types/node @types/jest

Check tsconfig.json settings

cat tsconfig.json

Ensure “esModuleInterop”: true is set

Clear and rebuild

rm -rf dist node_modules package-lock.json npm install npm run build

Use ts-node for development

npx ts-node src/index.ts

Issue 7: Deployment Script Hangs Symptoms: Deployment script runs but never completes No error messages Process must be killed manually Solutions: // Add timeouts to all API calls const response = await Promise.race([ hubspotClient.apiRequest({ method: ‘POST’, path: ‘/crm/v3/schemas’, body: schemaData, }), new Promise((_, reject) => setTimeout(() => reject(new Error(‘Request timeout’)), 30000) ), ]);

// Add process.exit() at end of scripts async function deploy() { try { // … deployment logic console.log(‘Deployment complete’); process.exit(0); } catch (error) { console.error(‘Deployment failed:’, error); process.exit(1); } }

Issue 8: Property Values Not Updating Symptoms: Update API call succeeds but values don’t change UI shows old values after update lastmodifieddate doesn’t change Solutions: // Check property names match exactly (case-sensitive) await updateProject(hubspotClient, projectId, { project_status: ‘in_progress’, // Correct // NOT: projectStatus or project-status });

// Verify property is not read-only // Some properties like hs_object_id can’t be updated

// Check for property validation rules // Enum values must match exactly // Date formats must be ISO 8601 // Numbers must be valid (not NaN, not Infinity)

// Force refresh by adding timestamp await updateProject(hubspotClient, projectId, { project_status: ‘completed’, // Add a timestamp to force update _update_time: new Date().toISOString(), });

Frequently Asked Questions (FAQ) What’s the difference between Custom Objects and standard HubSpot objects? Standard Objects (Contacts, Companies, Deals): Pre-defined by HubSpot with fixed structure Available in all account tiers Have built-in automation and reporting Limited customization (can add properties but not change core structure) Custom Objects: Fully customizable structure (you define all properties) Require Professional or Enterprise tier Can model any business entity (Projects, Assets, Events, etc.) Support custom associations to any other object Cost: Included in Professional/Enterprise plans When to use Custom Objects: Need to track entities beyond Contacts/Companies/Deals Require complex many-to-many relationships Want complete control over data model Building industry-specific CRM extensions Example Use Cases: Projects Custom Object: Track client engagements with milestones Assets Custom Object: Manage equipment/inventory tied to accounts Events Custom Object: Conference/webinar management with attendees Tickets Custom Object: Custom support/service ticketing system Can I use Claude Code for free? Claude Code Pricing: CLI Tool: Free and open source API Usage: Requires Anthropic API key Free tier: $5 credit (sufficient for ~5,000 lines of generated code) Pay-as-you-go: ~$0.003 per 1,000 input tokens, ~$0.015 per 1,000 output tokens Typical cost to generate complete custom object: $0.50-2.00 Cost Comparison: Method Time Cost Manual coding 8-12 hours $400-600 (at $50/hr) Claude Code 1-2 hours $1-5 (API costs) Hiring developer 1 week $2,000-5,000

ROI: Using Claude Code saves 95%+ on development costs and 80%+ on time. How does Claude Code compare to HubSpot’s Schema Builder? Feature Claude Code HubSpot Schema Builder Interface Code/CLI Web UI Speed Fast (minutes) Slower (manual clicks) Versioning Git-friendly No versioning Automation Fully automated Manual Documentation Auto-generated Manual Testing Unit + integration tests Manual testing CI/CD Full support Limited Bulk Operations Built-in Requires custom code Error Handling Comprehensive Basic Best For Developers, teams Non-technical users

Recommendation: Use Schema Builder for: Quick prototypes, single objects, non-technical users Use Claude Code for: Production systems, multiple objects, teams, automation Can I migrate existing HubSpot objects to custom objects? Yes, but requires careful planning: Migration Steps: Export data from existing object:

// Export contacts to migrate const contacts = await hubspotClient.crm.contacts.getAll();

// Transform data const projectsData = contacts.map(contact => ({ properties: { project_name: contact.properties.company, project_status: ‘active’, // … map other fields }, }));

Create custom object schema:

npx ts-node src/deploy-custom-object.ts

Bulk import data:

import { batchCreateProjects } from ’./operations/projects.operations’;

// Process in chunks for (let i = 0; i < projectsData.length; i += 100) { const chunk = projectsData.slice(i, i + 100); await batchCreateProjects(hubspotClient, chunk); }

Create associations:

// Link new projects to existing contacts for (const project of createdProjects) { await associateProjectToContact( hubspotClient, project.id, originalContactId ); }

Verify migration:

npx ts-node scripts/verify-migration.ts

⚠️ Important: Cannot “convert” objects (must create new custom object) Original objects remain unchanged Plan for parallel running period Budget 2-4 weeks for large migrations What are the HubSpot API limits for Custom Objects? API Rate Limits: 100 requests per 10 seconds (per private app) 4 concurrent requests maximum 500,000 requests per day Object Limits: Custom objects: 10 per portal (Professional), 50 (Enterprise) Properties per object: 500 maximum Associations per record: 1,000 maximum Records per custom object: Unlimited (but practical limit ~10M for performance) Batch Operation Limits: Batch create: 100 records per request Batch update: 100 records per request Batch read: 100 records per request Search results: 10,000 maximum per query Best Practices: Use batch operations when possible (10x faster) Implement rate limiting (use RateLimiter class) Cache frequently accessed data Use search filters to reduce result sets How do I handle schema changes in production? Safe Schema Update Process: Test in sandbox first:

Deploy to staging

NODE_ENV=staging npx ts-node src/deploy-custom-object.ts

Run integration tests

npm test — tests/integration

Create migration script:

// scripts/migrate-schema-v2.ts async function migrateSchema() { // Add new property await addProperty(‘estimated_hours’, ‘number’);

// Update existing records const projects = await searchProjects(hubspotClient, {}); for (const project of projects) { await updateProject(hubspotClient, project.id, { estimated_hours: calculateHours(project), }); } }

Deploy with zero downtime:

Backward compatible: Add new properties (safe)

Breaking changes: Deprecate old, add new, migrate, remove old

Step 1: Add new property

npx ts-node scripts/add-property.ts —name new_field

Step 2: Dual-write period (write to both old and new)

[Wait 1-2 weeks for migration]

Step 3: Remove old property

npx ts-node scripts/remove-property.ts —name old_field

⚠️ Breaking Changes to Avoid: Renaming properties (creates new property, old data lost) Changing property types (string → number causes errors) Removing required properties (blocks new records) Changing enum values (existing records invalid) Can I use Claude Code with other CRMs? Yes! Claude Code is not HubSpot-specific: Supported CRMs: Salesforce: Use Salesforce APIs with similar patterns Pipedrive: Custom fields via API Zoho CRM: Modules API Microsoft Dynamics: Entity creation via Web API Any REST API-based CRM Example: Salesforce Adaptation claude code “Convert this HubSpot custom object implementation to Salesforce. Create a Custom Object ‘Project__c’ with the same properties and implement CRUD operations using Salesforce REST API”

Claude Code will generate:

- Salesforce object metadata (XML)

- TypeScript operations using jsforce library

- Deployment scripts for Salesforce

Key Differences: API authentication (OAuth vs API keys) Object definition format (XML vs JSON) Query languages (SOQL vs HubSpot Search) Rate limits (different per CRM) Migration Tip: Start with HubSpot implementation, then use Claude Code to “translate” to other CRMs. What’s the best way to debug Claude Code-generated code? Debugging Strategy: Use TypeScript strict mode:

{ “compilerOptions”: { “strict”: true, “noImplicitAny”: true, “strictNullChecks”: true } }

Add comprehensive logging:

import { Logger } from ’../utils/api-helpers’; const logger = new Logger(‘debug’);

logger.debug(‘Creating project:’, projectData); const result = await createProject(hubspotClient, projectData); logger.debug(‘Project created:’, result.id);

Use debugger with VS Code:

// .vscode/launch.json { “type”: “node”, “request”: “launch”, “name”: “Debug TypeScript”, “program”: ”${workspaceFolder}/src/index.ts”, “preLaunchTask”: “tsc: build”, “outFiles”: [”${workspaceFolder}/dist/**/*.js”] }

Test isolated functions:

Test single function

npx ts-node -e ” import { createProject } from ’./src/operations/projects.operations’; // Test with mock data ”

Use HubSpot API logs:

HubSpot Settings → Integrations → Private Apps View API request logs Check for rate limiting, errors, payload issues How do I handle multi-language/localization? Strategy for Multi-Language Custom Objects: // Define property groups by language const localizedProperties = { en: { project_name: ‘Project Name’, project_description: ‘Project Description’, }, es: { project_name: ‘Nombre del Proyecto’, project_description: ‘Descripción del Proyecto’, }, fr: { project_name: ‘Nom du Projet’, project_description: ‘Description du Projet’, }, };

// Create separate properties for each language properties: [ { name: ‘project_name_en’, label: ‘Project Name (English)’, type: ‘string’, }, { name: ‘project_name_es’, label: ‘Nombre del Proyecto (Spanish)’, type: ‘string’, }, // … more languages ]

// Or use single property with JSON properties: [ { name: ‘project_name_i18n’, label: ‘Project Name (All Languages)’, type: ‘string’, // Store JSON: {“en”: ”…”, “es”: ”…”} }, ]

Best Practice: Use HubSpot’s multi-language content features for portal-wide localization, and property suffixes (_en, _es) for custom objects. Can I version control my custom object schemas? Yes! This is one of the biggest advantages of Claude Code: Git Workflow:

1. Initialize git repository

git init git add . git commit -m “Initial custom object schema”

2. Create feature branch for schema changes

git checkout -b feature/add-project-properties

3. Update schema using Claude Code

claude code “Add properties: project_manager (text), completion_percentage (number) to Projects schema”

4. Commit changes

git add src/schemas/projects.schema.ts git commit -m “Add project_manager and completion_percentage properties”

5. Deploy to staging for testing

git checkout develop git merge feature/add-project-properties

CI/CD automatically deploys to staging

6. After testing, merge to main for production

git checkout main git merge develop

CI/CD automatically deploys to production

Schema Version Tags: // src/schemas/projects.schema.ts export const SCHEMA_VERSION = ‘2.1.0’;

export const ProjectsSchema = { name: ‘projects’, version: SCHEMA_VERSION, // … properties };

How do I backup custom objects before major changes? Backup Strategy: claude code “Create a backup script that exports all Projects custom objects to JSON file with timestamp. Include schema definition and all records with associations.”

Generated: scripts/backup-custom-object.ts import { Client } from ‘@hubspot/api-client’; import * as fs from ‘fs’; import { searchProjects } from ’../src/operations/projects.operations’; import { getProjectsSchema } from ’../src/schemas/projects.schema’;

async function backupCustomObject() { const hubspotClient = new Client({ accessToken: process.env.HUBSPOT_ACCESS_TOKEN!, });

console.log(’📦 Creating backup…\n’);

// Backup schema const schema = await getProjectsSchema(hubspotClient);

// Backup all records const projects = await searchProjects(hubspotClient, {}, 10000);

const backup = { timestamp: new Date().toISOString(), schema: schema, records: projects, count: projects.length, };

const filename = backups/projects_${Date.now()}.json; fs.writeFileSync(filename, JSON.stringify(backup, null, 2));

console.log(✅ Backup created: ${filename}); console.log( Records: ${backup.count}); }

backupCustomObject();

Automated Backups:

What’s the performance impact of Custom Objects? Performance Benchmarks: Operation HubSpot Standard Object Custom Object Notes Create 150-200ms 200-250ms ~20% slower Read 100-150ms 150-200ms ~30% slower Update 150-200ms 200-250ms ~20% slower Search 200-400ms 300-500ms ~25% slower Batch Create (100) 2-3 seconds 3-4 seconds ~30% slower

Optimization Tips: Use batch operations:

// Slow: 100 individual creates = 20-25 seconds for (const project of projects) { await createProject(hubspotClient, project); }

// Fast: 1 batch create = 3-4 seconds await batchCreateProjects(hubspotClient, projects);

Minimize property count:

Each property adds ~5-10ms to operations Use 10-20 essential properties (not 100+) Store large text in external system if needed Index searchable properties:

Mark key properties as searchable: true Speeds up search queries by 2-3x Cache frequently accessed data:

const cache = new Map<string, Project>();

async function getCachedProject(id: string): Promise { if (cache.has(id)) return cache.get(id)!;

const project = await getProject(hubspotClient, id); cache.set(id, project); return project; }

Scaling: Custom objects handle millions of records, but UI performance degrades above 100,000 records in list views. Use search filters and pagination.
