Use your GHL API credentials to securely sign requests. Store keys safely in Zapier and apply the proper scopes (readonly for browsing, write for updating).
In Zapier, create a connection using your GHL credentials. This connection securely handles token refreshes and request signing for every API call.

You can authenticate with API keys or OAuth, depending on your GHL setup. In Zapier, add a connection using your credentials and assign the appropriate scopes (read or write) to control access. Maintaining secure storage of credentials and rotating keys regularly is advised. Always test authentication in a controlled environment before going live to ensure your workflows run smoothly.
Start with retrieving a specific contact to understand data structure: GET /contacts/:contactId. Then add creation with POST /contacts/ to bring new records into GHL. As you expand, use GET /contacts/ to fetch lists and GET /contacts/business/:businessId for business-wide views. Document field mappings between your source app and GHL to prevent data drift.
Respect rate limits by batching requests when possible and by implementing exponential backoff on errors. Use the GET endpoints for read-heavy tasks and reserve write operations for critical updates. Monitor your quota in the GHL developer dashboard and adjust cadence accordingly. If you exceed limits, pause requests briefly and retry with updated parameters to avoid data loss.
Yes. Use PUT /contacts/:contactId to update existing contacts and PATCH-like behavior can be achieved with PUT for changed fields. Deleting a contact is done via DELETE /contacts/:contactId. Ensure you maintain a history or audit trail within your app to track changes. Test updates in a staging environment before applying to production workflows.
To create tasks for a contact, call POST /contacts/:contactId/tasks with a task payload containing title, due date, and priority. You can then update or complete tasks with the corresponding endpoints. Consider mapping trigger data from your source app to task attributes to keep tasks synchronized.
Yes. Use GET /contacts/ to list all contacts or GET /contacts/business/:businessId to filter by business. Combine with pagination and filters to efficiently retrieve large sets. Store retrieved IDs for incremental syncing in subsequent runs.
API documentation and examples are available in the GHL developer portal. Look for sections on Contacts API endpoints, authentication, and sample payloads. Many Zapier tutorials link to endpoint references to speed up integration. If you need concrete payload examples, start with a simple contact create and expand from there.
Due to high volume, we will be upgrading our server soon!
