To access the GHL Contacts API from Zapier you need a valid API key or OAuth token with the scope contacts.readonly. Store credentials securely and rotate tokens periodically.
Connect Zapier to the GHL account using OAuth2 credentials or a token provided by the App Connector. Ensure scopes allow read access during testing
Endpoints include the following read and write operations for contacts: GET /contacts/:contactId GET /contacts/:contactId/tasks GET /contacts/:contactId/tasks/:taskId GET /contacts/:contactId/notes GET /contacts/:contactId/notes/:id GET /contacts/:contactId/appointments GET /contacts/ GET /contacts/business/:businessId contacts.write POST /contacts/ PUT /contacts/:contactId DELETE /contacts/:contactId POST /contacts/:contactId/tasks PUT /contacts/:contactId/tasks/:taskId PUT /contacts/:contactId/tasks/:taskId/completed DELETE /contacts/:contactId/tasks/:taskId POST /contacts/:contactId/tags
Trigger example: a new or updated contact starts a workflow to fetch details and related tasks
Actions: create or update notes, add tags, or assign tasks
GET /contacts/:contactId
Key fields include contactId, name, email, phone
Trigger: updates to a contacts notes or tasks trigger a Zap to sync with other tools
Actions: create or update tasks and notes across apps
GET /contacts/:contactId/tasks
Key fields: contactId, taskId, noteId, status
Trigger: scheduled pull of a business contact list to keep CRM in sync
Actions: upsert contacts and attach notes
GET /contacts/business/:businessId
Key fields: businessId, contactId, name
Automate data flows without writing code
Leverage built in connectors to speed up delivery
Easily map fields between GHL and other apps
Here are key elements and processes to understand the integration
API is a set of rules for how software components communicate
An endpoint is a URL and method to access a resource in an API
A mechanism for apps to send real time data to another app
OAuth2 is an authorization framework that lets third party apps access user data securely
When a new contact is created in GHL pull details and automatically create starter notes and tasks through Zapier
Use the completed status to push a record to a timeline feed in other apps
Periodically export business contacts to a spreadsheet or BI tool for analysis
Obtain API key or OAuth token with the correct scope and test using the built in tester
In Zapier map contact fields to your app fields and set triggers such as contact created or updated
Create actions like add task or update notes then run a test Zap
You can read contact data such as contactId name email and phone with read operations. You can also fetch related tasks notes appointments. For more complex flows you can combine triggers with actions to build multi step automations.
The integration uses OAuth2 or API keys depending on setup. Use tokens with proper scopes. Rotate credentials and store securely. When testing ensure your app scopes are set to readonly for safety.
Write operations are supported for creating and updating contacts and tasks via endpoints 10 11 13 14 15 and 16 and 17. Use appropriate HTTP methods. Not all endpoints may be enabled in every plan; verify with your admin.
Rate limits depend on your GHL plan and token type. If you reach limits, implement backoff and retries. Consider batching requests and caching data where possible.
Field mapping is done in Zapier during setup by linking GHL contact fields to your app fields. Use sample data to validate. Keep mapping updated when fields change in GHL.
Yes you can fetch contacts by business using endpoint GET /contacts/business/:businessId. You can then filter or paginate results in Zapier. This is ideal for CRM workflows and reporting.
Endpoint list is documented in the Endpoints section of this guide. You can access it via the ENDPOINTLIST token. If you need additional endpoints we can expand the listing.
Due to high volume, we will be upgrading our server soon!
