GHL uses OAuth 2.0 with scopes such as contacts.readonly to securely access data. Store tokens securely and renew them as needed.
In Zapier, authorize the connection to GHL via OAuth 2.0 and grant the required scopes. The connector manages token refresh automatically.
Available 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 when a contact is created or updated in GHL to push updates to Zapier and downstream apps.
Actions: create or update a contact in GHL from Zapier.
GET /contacts/:contactId
Key fields: contactId, email, firstName, lastName
Trigger when a new task is created for a contact in GHL.
Actions: create a task under a contact with status and dueDate.
POST /contacts/:contactId/tasks
Key fields: contactId, taskId, title, dueDate
Trigger when a tag is added or removed from a contact.
Actions: apply or remove tags on a contact.
POST /contacts/:contactId/tags
Key fields: contactId, tagId, tagName
Rapid setup with drag-and-drop workflows requires no code.
Scales with your business as you add more endpoints and workflows.
Centralized data flow reduces manual data entry and errors.
This glossary defines terms for endpoints, authentication, and data flows used when connecting GHL with the Zapier App Connector.
A URL that allows a client app to access or manipulate data in an API.
An authorization framework that lets apps obtain limited access to user data without sharing passwords.
A credential that grants you access to the API for a limited time.
A URL that a server can call to notify your app about events.
Capture new contacts from your app and instantly create them in GHL with a welcome task.
Use Zapier to pull notes and tasks into GHL to keep records up to date.
Apply tags based on behavior and field values to organize audiences.
Start by granting OAuth access to both sides and selecting the Contacts API scope.
Choose the endpoints you need (for example, GET /contacts/:contactId and POST /contacts/:contactId/tasks) and map fields.
Run tests in Zapier’s test flow, then enable the connection for automation.
We use OAuth 2.0 for authentication. You’ll grant access once to connect your GHL Contacts API with the Zapier App Connector. The connector then handles token refreshes automatically. This keeps your credentials secure and minimizes manual steps. You can revoke access at any time from either platform. The scopes determine what data is accessible, with typical read-only or write permissions as needed.
Core endpoints include retrieving a contact, fetching tasks and notes, managing appointments, and creating or updating records. Examples are GET /contacts/:contactId, POST /contacts/, POST /contacts/:contactId/tasks, and POST /contacts/:contactId/tags. The available endpoints can be tailored to your use case by selecting only the needed ones in the Zapier connector.
Yes. You can create or update a contact from Zapier by using POST /contacts/ or PUT /contacts/:contactId. You can also add tasks or tags to an existing contact. Map the fields from your trigger app to the GHL fields to ensure data consistency.
Security relies on OAuth 2.0 with short-lived tokens and encrypted connections (HTTPS) for all API calls. Access scopes limit what the connector can do, and you retain control to revoke access if needed. Regular token refresh minimizes exposure and keeps sessions valid.
Most critical data syncs happen in near real-time as triggers fire. Some workflows run on a schedule or when explicit actions occur in Zapier. If you need strict real-time behavior, configure triggering on create/update events in GHL for immediate propagation.
Zapier enforces rate limits based on your plan. If you hit a limit, the connector will retry according to Zapier’s policy. You can optimize by batching actions or enabling fewer endpoints in a single workflow.
Endpoint docs are available in the developer guides for the Contacts API. Use the endpoint list above as a quick reference and consult the full docs for parameter details, response schemas, and error codes. You can also test endpoints directly in your Zapier connection setup.
Due to high volume, we will be upgrading our server soon!
