To securely access the Contacts API from Zapier App Connector, obtain your API credentials and choose the appropriate scope (readonly). Use OAuth 2.0 when available, or an API key for simpler setups.
In Zapier, connect to the Contacts API using OAuth 2.0 or an API key. Store tokens securely and refresh as needed within your Zapier connection settings.
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; 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

This section defines essential data elements and the end-to-end process for connecting GHL’s Contacts API to the Zapier App Connector.
An exposed URL that lets you access or manipulate a particular resource in the GHL API.
The method by which your app proves identity to GHL (e.g., OAuth 2.0, API keys).
The maximum number of API calls allowed in a given period to protect service stability.
A callback URL that GHL calls to notify your app of events.
Create a Zap that creates a contact in GHL when a new lead is added in your CRM, then trigger a welcome task.
Keep notes and tags in sync between GHL and your app when changes occur.
Create tasks in Contacts API from events in your app and automatically close them when completed.
Register an app in GHL, obtain client credentials, and set the correct scope (contacts.readonly).
In Zapier, add a connection and authorize access to Contacts API with your credentials.
Choose a trigger (e.g., New contact) and define actions (e.g., create or update contact, tag, etc.).
You can authenticate using OAuth 2.0 when supported by the API, or an API key for simpler setups. In Zapier, connect using the OAuth flow or key-based auth, ensuring your app has the necessary scopes (such as contacts.readonly). Regularly rotate credentials and utilize secure storage.
For typical workflows, focus on endpoints that read and write contact records (GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId). Use tasks and notes endpoints to manage related data. This combo supports powerful CRM automation with minimal code.
GHL imposes rate limits to protect service health. When building Zaps, design with idempotent actions and implement retry logic. If you hit a limit, back off and retry after a short interval.
Yes. You can update a contact’s details with PUT /contacts/:contactId or create new contacts with POST /contacts/. Zapier can trigger updates based on changes in your source systems and push those updates to GHL.
Zapier automatically retries failed actions depending on the error. You can configure error handling in your Zap to catch failures, pause the workflow, or push notifications for manual remediation.
Webhooks are supported for event-driven updates. You can configure a webhook endpoint to receive GHL events and trigger Zaps. Ensure your endpoint is secured and validated.
API credentials are found in your GHL developer console or account settings. Create an app, generate client credentials or API keys, and grant the appropriate scopes. Store these securely in Zapier’s connection settings.
Due to high volume, we will be upgrading our server soon!
