Set up a secure connection from Zapier to the GHL Contacts API using OAuth 2.0 with the required scope (contacts.readonly). After you authorize, Zapier will be able to access contact data and related resources.
Connect the Zapier App Connector to your GHL account by selecting the Contacts API connection and granting the necessary permissions to run triggers and actions.
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; Scope: 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: When a contact is retrieved or updated to sync related data in Zapier
Actions: Retrieve contact details plus related data using the GET endpoints for tasks, notes, and appointments
GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments
contactId, taskId, noteId, appointmentId
Trigger: New or updated contact or task
Actions: Create and update contacts and tasks using POST, PUT, and DELETE endpoints (e.g., POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId)
POST /contacts/; PUT /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId
contactId, taskId
Trigger: Tag changes or business linkage events
Actions: Add tags to a contact (POST /contacts/:contactId/tags) and fetch business associations (GET /contacts/business/:businessId)
POST /contacts/:contactId/tags; GET /contacts/business/:businessId
businessId, contactId, tag
Launch integrations in minutes without writing code, using the Zapier App Connector to talk to the GHL Contacts API.
Automate data flows across contacts, tasks, notes, and tags to save time and reduce errors.
Gain full visibility and control with repeatable, auditable workflows across apps.
Key elements include endpoints, authentication, data mapping, triggers, actions, error handling, and retries, all designed for a smooth no-code integration.
The process of proving identity and granting access to the GHL Contacts API, typically via OAuth 2.0 or API tokens.
A specific API URL used to perform an operation on a resource (for example, GET /contacts/:contactId).
A set of permissions granted to an app to access specific API features, such as contacts.readonly or contacts.write.
A cap on API requests in a given time window to protect services from abuse and ensure reliability.
When a contact is updated in GHL, pull related data (tasks, notes, appointments) and update Zapier fields to keep systems in sync.
Create and update tasks in GHL from triggers in your other apps, so teams stay aligned without manual entry.
Automatically assign tags and link contacts to businesses based on events to improve segmentation and targeting.
Step 1: In Zapier, create a new connection and authorize the GHL Contacts API with the required scope.
Step 2: Map data fields between GHL and Zapier actions, and select the endpoints you will use (read and/or write).
Step 3: Run tests, verify data flows, and enable the automation in production.
OAuth 2.0 with scoped access is supported; you’ll authorize a connection in Zapier and grant the necessary permissions. If API tokens are used, keep them secure and rotate credentials regularly.
Read operations include GET endpoints like /contacts/:contactId, /contacts/:contactId/tasks, /contacts/:contactId/notes, and /contacts/:contactId/appointments. Write operations include POST, PUT, and DELETE calls such as creating contacts or tasks, updating them, marking tasks complete, and tagging contacts.
Yes. You can retrieve a contact’s tasks and notes using the GET endpoints. You can also combine data in a Zap by issuing multiple GET calls or modeling related data relationships where supported.
Use Zapier’s field mapping to align GHL response fields (name, email, tasks, notes) with your Zap steps. Create custom mappings for nested fields like taskId or noteId as needed.
Yes, API requests may be rate-limited; plan automations to batch requests when possible. If you hit a limit, implement exponential backoff and retry logic in your Zap.
Use Zapier’s test feature to run sample payloads against the GHL Contacts API and validate responses. Check logs and monitor for errors before enabling live automation.
Define a consistent tag taxonomy and clearly map business relations in the Contacts endpoint to avoid ambiguity. Document your mappings and maintain version control for configuration changes.
Due to high volume, we will be upgrading our server soon!
