To access the Contacts API, supply your API key and ensure the requested scope is contacts.readonly. Store credentials securely and test calls with a lightweight request first.
In Zapier, connect the App Connector to your GHL Contacts API credentials, select the correct environment, and test the connection to confirm access.

You don’t need to be a developer for basic connections; a well-designed app connector and the provided keys can get you started. Start with read-only access to confirm endpoints are reachable. If your use cases require updates, you can add write permissions and test each operation incrementally.
Common tasks typically involve retrieving a contact, its tasks, notes, and appointments. You’ll map the contactId (and related fields) to your Zapier trigger and configure actions to create or update records as needed.
Rate limits depend on your GHL plan and API usage. Plan for bursts during automation launches and implement retries with exponential backoff to stay within quotas.
Yes. You can update contacts and tasks using PUT and POST endpoints. Make sure to pass the correct contactId and taskId, and validate responses in your Zapier task history.
Store keys securely, rotate periodically, and use environment variables in Zapier. Never expose keys in logs or client code.
Fields such as contactId, name, email, phone, tags, tasks, notes, and appointments are typically mappable. Use the endpoint responses as your field sources and map to your destination app fields.
