Authenticate requests to the Contacts API via the Zapier App Connector using API keys or OAuth 2.0 credentials.
Zapier App Connector uses OAuth 2.0 or API tokens to authorize access to the Contacts API within your automations.
The Contacts API offers endpoints to retrieve and manage contacts, tasks, notes, and appointments including bulk and specific item operations.
Trigger workflows when a contact is created or updated to keep systems in sync.
Actions can create tasks, notes, or appointments tied to the contact.
Key endpoints include GET /contacts/:contactId, POST /contacts/ and PUT /contacts/:contactId to sync data.
Important fields include contactId, name, email, and phone.
Automate task creation and status updates from support or sales events.
Create or update tasks via Zapier using endpoints like POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId.
Use endpoints such as POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId to manage tasks.
Key IDs include contactId and taskId.
Capture important interactions by triggering on new or updated notes.
Retrieve, create, or update notes to keep all communications in one place.
Endpoints include GET /contacts/:contactId/notes, POST /contacts/:contactId/notes and GET /contacts/:contactId/notes/:id.
Key fields include contactId and id for notes.
Automate repetitive tasks without writing code using ready made triggers and actions.
Centralize data flow across apps to keep contact records consistent.
Speed up onboarding with templates and test connections for quick deployment.
A concise glossary of terms and processes to help you implement the integration smoothly.
OAuth 2.0 is the authorization framework that allows apps to access the Contacts API on behalf of a user.
A specific URL path that performs an action on a resource, such as GET /contacts/:contactId.
A method for the API to push real time data to your app when an event occurs.
A data object exposed by the API such as a contact, task, or note.
Automatically push new form leads into Contacts API and create a contact, then trigger follow up tasks.
When a new ticket is created, generate a related task and assign to the right owner.
Add notes to contacts and ping customers with renewal reminders via automated campaigns.
Obtain your API key and set up OAuth credentials on the GHL side, then configure in Zapier.
Select endpoints like GET /contacts/:contactId and POST /contacts/ to map fields to your apps.
Run tests, verify data flow, and enable automation in production.
Zapier App Connector supports API key based and OAuth 2.0 authentication for the Contacts API. To begin, generate credentials on the GHL side and configure them in Zapier. This ensures secure access to contact data without exposing credentials in workflows. If you run into issues, use test connections and review scopes such as contacts.readonly to validate permissions before deploying automations.
Commonly used endpoints include GET /contacts/:contactId to fetch a contact and POST /contacts/ to create a new contact. For task management you will use POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId to update tasks. Notes and appointments endpoints are GET and POST for notes and appointments linked to a contact.
In Zapier, use the Test Connection option on the app configuration to validate credentials and permissions. Use sample payloads that reflect your real data and verify that fields map correctly to your target apps. Iteratively test each endpoint you plan to use to confirm data flows as expected.
Yes, you can update contacts using endpoints like PUT /contacts/:contactId. Map the fields you want to update in your Zap and ensure you have the proper permissions granted by your authentication scope. Always test updates in a staging environment before going live.
Yes, you can retrieve and manage notes via endpoints such as GET /contacts/:contactId/notes and POST /contacts/:contactId/notes. For tasks use GET and POST with the relevant contactId. This enables complete visibility of a contact’s interactions and tasks in one place.
Rate limits depend on your GHL account and OAuth configuration. Plan for bursts in usage by staggering requests and using batch operations where supported. If limits are hit, implement retry logic and backoff strategies in your Zapier automations.
A complete list of endpoints is available in the API documentation section of this page. You will find endpoints for contacts, tasks, notes, and appointments along with example payloads and required parameters.
Due to high volume, we will be upgrading our server soon!
