Zoho CRM

Access the Zoho CRM API with managed OAuth authentication. Manage leads, contacts, accounts, deals, and other CRM modules with full CRUD operations including search and bulk operations. Also supports organization details, user management, and module metadata retrieval.

Quick Start

# List leads
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/zoho-crm/crm/v8/Leads?fields=First_Name,Last_Name,Email')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

https://api.maton.ai/zoho-crm/crm/v8/{endpoint}

Maton proxies requests to www.zohoapis.com/crm/v8 and automatically injects your OAuth token.

Authentication

All requests require the Maton API key in the Authorization header:

Authorization: Bearer $MATON_API_KEY

Environment Variable: Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Copy your API key

Connection Management

Manage your Zoho CRM OAuth connections at https://api.maton.ai.

List Connections

import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections?app=zoho-crm&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Create Connection

import urllib.request, os, json
data = json.dumps({'app': 'zoho-crm'}).encode()
req = urllib.request.Request('https://api.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Get Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Response:

{
  "connection": {
    "connection_id": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",

import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Specifying Connection

If you have multiple Zoho CRM connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/zoho-crm/crm/v8/Leads?fields=First_Name,Last_Name,Email')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If you have multiple connections, always include this header to ensure requests go to the intended account.

Security & Permissions

• Access is scoped to leads, contacts, accounts, deals, and other CRM records within the connected Zoho CRM account.
• All write operations require explicit user approval. Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.

      "custom": false,
      "description": null
    }
  ]
}

Example - Get specific profile:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/zoho-crm/crm/v8/settings/profiles/7243485000000026011')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Pagination

Zoho CRM uses page-based pagination with optional page tokens for large datasets:

GET /zoho-crm/crm/v8/{module_api_name}?fields=First_Name,Last_Name&page=1&per_page=50

Response includes pagination info:

{
  "data": [...],
  "info": {
    "per_page": 50,
    "count": 50,
    "page": 1,
    "sort_by": "id",
    "sort_order": "desc",
    "more_records": true,
    "next_page_token": "token_value",
    "page_token_expiry": "2026-02-07T01:10:56-08:00"
  }
}

• For up to 2,000 records: Use page parameter (increment each request)
• For 2,000+ records: Use page_token from previous response
• Page tokens expire after 24 hours

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/zoho-crm/crm/v8/Leads?fields=First_Name,Last_Name,Email',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

import os
import requests

response = requests.get(
    'https://api.maton.ai/zoho-crm/crm/v8/Leads',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'fields': 'First_Name,Last_Name,Email'}
)
data = response.json()

Notes

• The fields parameter is required for list operations (max 50 fields)
• Module API names are case-sensitive (e.g., Leads, not leads)
• Maximum 100 records per create/update request
• Maximum 100 records per delete request
• Maximum 200 records returned per GET request
• Maximum 2,000 records without page_token; up to 100,000 with page_token
• Use field API names (not display names) in requests
• If you receive a scope error, contact Maton support at support@maton.ai with the specific operations/APIs you need and your use-case
• Empty datasets return HTTP 204 (No Content) with empty body
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets to disable glob parsing
• IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments

Error Handling

Common Error Codes

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

1. Verify the API key is valid by listing connections:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with zoho-crm. For example:

• Correct: https://api.maton.ai/zoho-crm/crm/v8/Leads
• Incorrect: https://api.maton.ai/crm/v8/Leads
