Use OAuth 2.0 to authorize access to your GHL account and grant the Zapier App Connector the required scope (contacts.readonly) to read contacts, tasks, notes, and appointments.
Once you authorize, Zapier App Connector will securely store a token and reuse it for subsequent requests to the Contacts API.
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 on contact updates to pull the latest data into connected apps.
Actions include retrieving contact details, tasks, notes, and appointments, ensuring downstream apps stay up to date.
GET /contacts/:contactId and related subpaths for tasks, notes, and appointments.
Key fields: contactId, email, or phone for matching records.
Trigger on new or updated contacts from the source app to push to GHL.
Actions: create or update /contacts/ via POST /contacts/ and PUT /contacts/:contactId.
POST /contacts/; PUT /contacts/:contactId
Key fields: email (preferred), name, and phone.
Trigger on tag changes to a contact.
Actions: add or remove tags using POST /contacts/:contactId/tags.
POST /contacts/:contactId/tags
Key fields: contactId, tag names.
Build powerful integrations without writing a line of code.
Automate routine data flows between GHL and your tools (CRM, helpdesk, marketing) instantly.
Secure, scalable access with OAuth 2.0 and granular scopes.
This guide defines core elements: endpoints, authentication, rate limits, and data mapping between GHL and the Zapier App Connector.
The official REST API provided by GHL to access Contacts data.
OAuth 2.0-based authentication for Apps.
Specific URL paths to perform operations on Contacts, Tasks, Notes, and Appointments.
Permissions that limit what data each app can read or modify.
When a new contact is added, automatically generate a starter task in your project management tool to ensure timely follow-ups.
Map contact properties to tags so status changes trigger automated workflows across apps.
Aggregate data from notes, tasks, and appointments into a single, up-to-date contact view.
Grant OAuth access to read contacts, tasks, notes, and appointments.
Choose the Contacts API, set scope to readonly, and test the connection.
Create field mappings for contacts, tasks, and notes, then enable automated flows.
The GHL Contacts API provides read access to contact records and related data such as tasks, notes, and appointments via endpoints like GET /contacts/:contactId and related subpaths. You can pull current contact details, view associated activities, and build dashboards or automation around this data. Scope governs what you can access; for this setup, use the contacts.readonly scope. Always handle data securely and in compliance with your policies.
No extensive coding is required when using the Zapier App Connector. You configure connections, scopes, and field mappings through the Zapier UI and use built-in triggers and actions. For advanced workflows, you can layer in filters and multi-step paths within Zapier. If you do need code, you can add simple custom steps, but it is not mandatory.
GHL imposes rate limits on API requests per account. When designing flows, space out requests, batch when possible, and implement retries with exponential backoff. In Zapier, use built-in delay and retry logic to stay within quotas while keeping your automation reliable.
Authentication is done via OAuth 2.0 in the Zapier App Connector interface. You’ll authorize the app to access your GHL data with the required scope (contacts.readonly). After consent, credentials are stored securely and will be refreshed automatically as needed.
Yes. You can create new contacts using POST /contacts/ and update existing ones with PUT /contacts/:contactId. Make sure to map key fields like email to prevent duplicates and to maintain data integrity across systems.
Tags can be managed with POST /contacts/:contactId/tags to add tags or update them as part of a workflow. Tag-based segmentation helps tailor communications and triggers across connected apps. Keep a consistent tag taxonomy to maximize automation.
Yes. Zapier’s test connections and the API playground let you validate endpoints with sample data before going live. Use the test feature to verify mappings, responses, and error handling in a safe environment.
Due to high volume, we will be upgrading our server soon!
