Use the OAuth 2.0 flow provided in your GHL dashboard to grant Zapier App Connector permission to read contact data (scope: contacts.readonly). For write actions, ensure your token has the appropriate scopes.
In Zapier, create a secure connection using OAuth credentials or an API key, then select the connected GHL Contacts API when building your workflow. Keep credentials confidential and rotate them periodically.
Endpoints include: 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, 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 on contact creation or updates in GHL to keep Zapier in sync with your CRM.
Actions include fetching a single contact, listing related tasks and notes, and retrieving or updating contact properties.

Required: contactId, title; Optional: dueDate, notes, priority
Trigger on note creation or updates for a contact
Actions: GET /contacts/:contactId/notes, POST /contacts/:contactId/notes, POST /contacts/:contactId/tags
Methods: GET /contacts/:contactId/notes; POST /contacts/:contactId/notes; POST /contacts/:contactId/tags

Run end-to-end tests, verify data flow, then launch.
For the Contacts API, use OAuth 2.0 or API Key depending on your setup; Zapier uses the connected app to authenticate. Ensure the token you generate includes the correct scopes for the actions you intend to perform. For read-only workflows, the scope should include contacts.readonly. If you need to write data, request broader scopes from your GHL administrator and ensure your app connection is approved for those permissions.
Read endpoints typically include GET /contacts/:contactId, GET /contacts/, GET /contacts/:contactId/notes, GET /contacts/:contactId/tasks. Write endpoints include POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, DELETE /contacts/:contactId, and POST /contacts/:contactId/tags. Map each action in Zapier to the corresponding endpoint based on your workflow needs.
Yes, you can update contact data via Zapier using PUT /contacts/:contactId and related endpoints for notes, tasks, and tags. Ensure your connection has write permissions and that you map fields correctly to the GHL contact fields. Validate changes in a test run before going live to avoid unintended updates.
Pagination is used to fetch large lists. Use limit and page parameters or the API’s pagination tokens if available. When building Zaps, store the next-page token and continue fetching until no more pages are returned. This ensures you can retrieve all contacts without missing data.
Real-time data is achievable through webhooks in GHL and supported polling in Zapier. If your workflow requires immediate updates, set up webhooks for create/update events and configure Zapier to respond to those events as triggers.
GHL enforces API rate limits. If you hit a limit, implement exponential backoff in your Zapier workflows and retry after the suggested window. Consider batching requests where possible and optimize field mappings to reduce unnecessary calls.
To test the integration, use Zapier’s built-in test feature to run sample triggers and actions with a test contact. Check that data maps correctly, endpoints respond as expected, and that success and error paths are properly handled in your Zap.
Due to high volume, we will be upgrading our server soon!
