Securely authenticate requests to the GHL Contacts API by using either API keys or OAuth as required by the API. Store credentials safely and rotate them regularly.
In Zapier App Connector, connect to the GHL Contacts API by supplying client credentials or an API key. Use OAuth when available for a seamless, token based connection.

Run tests and deploy automation to your team.
You can set up many automations without writing code using Zapier. The GHL Contacts API endpoints expose features that you can trigger and act on from Zapier. If you need customization you can still extend with simple code steps within Zapier.
Supported methods include API key based authentication and OAuth. Choose the method that matches your security requirements and the endpoint you access.
Core endpoints like GET /contacts and POST /contacts allow common CRM tasks. For more complex workflows you can combine tasks, notes and tags endpoints.
Most errors include a status code and message. Use retries with exponential backoff and verify credentials, endpoint paths, and payload schemas.
Yes. Zapier supports pagination with page size and page number parameters. Implement loop logic to fetch all pages if needed.
The API has rate limits based on your plan. Plan retries and backoff into your workflows to avoid hitting limits.
API docs and examples are available in the GHL developer portal and Zapier app docs. Look for endpoint references and sample payloads.
Due to high volume, we will be upgrading our server soon!
