Zoho Bigin

Access the Zoho Bigin API with managed OAuth authentication. Manage contacts, companies, pipelines, and products with full CRUD operations.

Quick Start

# List contacts
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/zoho-bigin/bigin/v2/Contacts?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-bigin/bigin/v2/{endpoint}

Maton proxies requests to www.zohoapis.com/bigin/v2 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 Bigin OAuth connections at https://api.maton.ai.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections?app=zoho-bigin&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

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'zoho-bigin'}).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",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "zoho-bigin",
    "metadata": {}
  }
}

Open the returned url in a browser to complete OAuth authorization.

Delete Connection

python <<'EOF'
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 Bigin 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-bigin/bigin/v2/Contacts?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 contacts, companies, pipelines, and products in Bigin CRM within the connected Zoho Bigin 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.

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/zoho-bigin/bigin/v2/Contacts?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-bigin/bigin/v2/Contacts',
    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
• Module API names are case-sensitive (e.g., Contacts, not contacts)
• Companies are accessed via the Accounts module API name
• Sales opportunities are accessed via the Pipelines module (not Deals)
• Maximum 100 records per create/update request
• Maximum 100 records per delete request
• Maximum 200 records returned per GET request
• Use field API names (not display names) in requests
• Some modules (Tasks, Events, Calls, Notes) require additional OAuth scopes. If you receive a scope error, contact Maton support at support@maton.ai with the specific operations/APIs you need and your use-case
• 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-bigin. For example:

• Correct: https://api.maton.ai/zoho-bigin/bigin/v2/Contacts
• Incorrect: https://api.maton.ai/bigin/v2/Contacts
