Use your GHL API credentials (Client ID and Client Secret) or API key to authorize requests from Zapier.
Zapier App Connector will use OAuth2 or an API key depending on the connector settings to securely call the GHL 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; 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 a contact lookup or update to pull in latest data.
Actions include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments.
GET /contacts/:contactId
Key fields: contactId, appointmentId (for related records), taskId (for tasks).
Trigger when a new contact is added to a business or when a bulk fetch is needed.
Actions include GET /contacts/ and GET /contacts/business/:businessId.
GET /contacts/; GET /contacts/business/:businessId
Key fields: businessId; contactId
Trigger on contact events to create tasks.
Actions include POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, and DELETE /contacts/:contactId/tasks/:taskId.
POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId
Key fields: contactId; taskId
Rapid automation setup without writing code.
Centralized data flow across CRM, tasks, notes, and appointments.
Faster onboarding and fewer manual errors.
This glossary defines the core elements and processes used when integrating GHL’s Contacts API with the Zapier App Connector.
A defined URL and HTTP method used to access or modify data in the GHL API.
Methods used to prove identity and authorize API requests (OAuth2, API keys, or tokens).
A data object exposed by the API, such as a Contact, Task, or Note.
Limits on how many requests can be made in a given time window.
Trigger on contact updates to generate follow-up tasks with due dates.
Push new notes to the contact as tickets update and provide a complete history.
Aggregate tasks and timelines into a single view for faster decisions.
Obtain client credentials from GHL and configure the Zapier app.
Use OAuth2 or API token to authorize; run a test to fetch a sample contact.
Create a Zap that uses GET endpoints to read contacts and tasks and triggers actions.
The GHL Contacts API exposes programmatic access to contact data, tasks, notes, and appointments for automation. Using the Zapier App Connector, you can read contacts and related records to automate workflows without manual data entry.
No traditional coding is required. The Zapier connector provides triggers and actions that map to API endpoints. If you need more complex logic, you can add filters and code steps within Zapier, but basic flows are no-code.
Commonly used endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/ and GET /contacts/business/:businessId, among others. The full list is available in the ENDPOINTLIST.
Authentication is handled by the Zapier connector using OAuth2 or API keys. You will configure credentials in GHL and authorize the Zapier app to access your data.
Yes. You can create and update contacts via endpoints like POST /contacts/ and PUT /contacts/:contactId. You can also manage tasks and notes associated with a contact.
Rate limits exist to protect the API and vary by plan. If you hit limits, implement exponential backoff in your Zap, or stagger requests to avoid throttling.
Best practice is to fetch data in small batches and cache where possible. Use unique identifiers (contactId, taskId) to keep records in sync and avoid duplicates.
Due to high volume, we will be upgrading our server soon!
