To access the Contacts API, configure OAuth2 or API key authentication in your GHL account and supply credentials to the Zapier App Connector.
Zapier securely stores and handles credentials to authenticate with GHL on your behalf; set up a connection and test.

Schedule weekly reminders for inactive contacts.
Log in to GHL and authorize Zapier to access your Contacts API.
Select contact-related endpoints you want to sync, such as contacts, tasks, and notes.
Run test triggers and actions, then deploy to production.
Authentication is usually done via OAuth2 with your GHL account. In Zapier, create a new connection and follow the prompts to grant access. Alternatively, if your setup supports API keys, generate a key in GHL and provide it to the Zapier app connector to authenticate requests.
The Contacts API exposes endpoints for retrieving and managing contacts, notes, tasks, and appointments. Key endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments.
Yes. Use POST /contacts/:contactId/tasks to create tasks attached to a contact. Zapier can trigger on task creation or update to drive downstream automations.
GHL enforces API rate limits based on your plan and endpoint. Exceeding limits returns 429. Best practice is to batch requests and implement exponential backoff in your Zapier workflows.
Use the error handling features in Zapier to catch 4xx/5xx responses and retry with backoff. Log errors and provide meaningful messages in your app to diagnose issues quickly.
Yes, you can update notes via PUT /contacts/:contactId/notes or similar endpoints. Ensure you have permission to modify notes and validate payload formats.
Test in a sandbox or using Zapier’s test mode to verify triggers and actions without affecting live data. Review logs and adjust mappings as needed before going to production.
Due to high volume, we will be upgrading our server soon!
