Use OAuth 2.0 or API Key authentication as supported by the GHL Contacts API. Store credentials securely in Zapier.
Zapier uses OAuth 2.0 for most connections or API keys for legacy apps. Create a new connection to authorize access.

Answer: Yes, many endpoints allow read operations to fetch contact data, tasks, notes, and appointments. Some endpoints enable write actions such as creating or updating records when you have the proper permissions and authentication. Always validate your access level in your GHL account and test in a sandbox environment first. This page covers best practices for safely using the API with Zapier.
Answer: Writing to the API is supported via endpoints like POST /contacts/ and PUT /contacts/:contactId; however, you must have the required permissions and scopes (e.g., contacts.write). Ensure you handle rate limits and data validation to avoid errors in automation.
Answer: Authentication is typically done via OAuth 2.0 or API keys. In Zapier, create a connection to authorize access to the GHL Contacts API and store credentials securely. Review scopes to ensure access to the needed resources.
Answer: The available endpoints include listing contacts, retrieving a single contact, managing tasks and notes, and basic CRUD operations on contacts. See the Endpoints section for a full list and usage notes. Use those endpoints in triggers and actions within your Zap.
Answer: Common issues include invalid credentials, insufficient permissions, or hitting rate limits. Check your connection status in Zapier, verify the scope (contacts.readonly vs contacts.write), and consult API docs for endpoint requirements.
Answer: Yes. You can set up triggers such as a new contact or updated task in GHL and drive actions in other apps via Zapier, enabling cross-tool automation and alerts.
Answer: API documentation is available in the GHL developer portal and via the Zapier app directory. Ensure you review authentication, rate limits, and endpoint usage examples.
