Access to the GHL Contacts API requires an OAuth 2.0 flow or an API key mechanism provided by your GHL workspace. Generate credentials in your GHL developer portal and grant scopes for contacts.readonly.
In Zapier, configure OAuth 2.0 with the GHL app, supply client ID/secret, and set redirect URLs. Test tokens and refresh securely.
Primary 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, and standard write/update/delete endpoints including 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: New or updated contact in GHL triggers an action in Zapier to create or refresh a record in your system.
Actions: Upsert contact data, map fields (name, email, phone), attach notes.
GET /contacts/:contactId
Key fields: id, email, firstName, lastName, phone, tags
Trigger: Appointment created or updated in GHL.
Actions: Create or update calendar events, sync status.
POST /contacts/:contactId/appointments
Key fields: appointmentId, dateTime, duration, attendee
Trigger: Task or note created in GHL.
Actions: Create tasks, attach notes, link to contact.
POST /contacts/:contactId/tasks
Key fields: taskId, title, dueDate, status
Benefit: Build end‑to‑end automations without writing code.
Benefit: Instant data sync across systems with reliable webhooks.
Benefit: Scalable workflows that adapt to your CRM, project management, and sales stack.

Register the Zapier app, obtain client credentials, and authorize access to GHL.
Choose triggers (New or Updated Contact, New Appointment, New Task) and map to Zapier actions.
Design actions to upsert data, create tasks, and attach notes, then run end-to-end tests.
The GHL Contacts API is a programmatic interface that lets you read and manage contact data, tasks, notes, and appointments. It enables you to fetch individual records or lists to drive automations in your stack. Start by identifying the data you need (contacts, tasks, notes, appointments) and map those fields into APPNAME actions. You can build no-code automations in Zapier that respond to GHL events and push data into downstream systems.
No traditional coding is required if you use Zapier App Connector with the GHL API. You can configure triggers, actions, and field mappings through a visual interface. If you need advanced logic, you can add small code steps in Zapier, but most automations run with configuration alone.
Key endpoints include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, GET /contacts/, 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. Use them to fetch, create, update, or delete data as part of your automations.
Authentication is typically handled with OAuth 2.0 between GHL and the Zapier app. In your GHL workspace, create an app, obtain client credentials, and configure redirect URLs in Zapier. Test the connection to ensure tokens refresh correctly and scopes include the required access to contacts data.
Yes. You can map fields such as name, email, phone, status, and custom fields between GHL and APPNAME. Use Zapier’s field mapping to ensure data types align and set up upsert logic to avoid duplicates. This makes data synchronization reliable across systems.
Webhooks are supported to push real-time updates from GHL to APPNAME. Configure webhooks for events like contact updates, new appointments, or new tasks, and route them through Zapier to trigger downstream actions.
Test by creating a sample contact, task, or appointment in GHL and verify the corresponding records update in APPNAME. Use Zapier’s test mode to monitor payloads, check field mappings, and confirm end-to-end data flow before going live.
Due to high volume, we will be upgrading our server soon!
