Use OAuth 2.0 with the Contacts API scope of readonly access to securely authorize Zapier App Connector. Rotate tokens regularly and keep credentials private.
Zapier App Connector authenticates to the Contacts API via OAuth 2.0, requesting the contacts.readonly scope. Complete the consent flow to enable smooth data access.
– GET /contacts/:contactId – GET /contacts/:contactId/tasks – GET /contacts/:contactId/notes – POST /contacts/ – PUT /contacts/:contactId – POST /contacts/:contactId/tasks – POST /contacts/:contactId/tags
Trigger: A contact is created or updated, then Zapier pulls the contact record and any associated tasks.
Actions: Retrieve contact details and list tasks; optionally log activity or update a CRM field in Zapier.
GET /contacts/:contactId and GET /contacts/:contactId/tasks
contactId, email, first_name, last_name, taskId
Trigger: New or updated contact triggers a new task to be created in the system.
Actions: POST /contacts/ to create a contact; POST /contacts/:contactId/tasks to assign a task.
POST /contacts/; POST /contacts/:contactId/tasks
first_name, last_name, email, phone; task_title, due_date
Trigger: Tags or notes change on a contact and syncs to Zapier.
Actions: POST /contacts/:contactId/tags to tag; GET /contacts/:contactId/notes to fetch notes; POST /contacts/:contactId/notes to add a note.
POST /contacts/:contactId/tags; GET /contacts/:contactId/notes; POST /contacts/:contactId/notes
contactId; tag_name; note_text
Automate repetitive contact workflows without writing code.
Build cross-app automations that respond to contact changes in real time.
Easily test, iterate, and deploy with Zapier’s built-in tooling.
This guide covers endpoints, authentication, triggers, actions, and data mapping between the GHL Contacts API and the Zapier App Connector.
The GHL REST API used to access contacts, tasks, notes, appointments, and more.
A specific URL path that performs an operation, such as GET /contacts/:contactId.
OAuth 2.0-based authentication with scopes like contacts.readonly to authorize Zapier App Connector.
A mechanism for real-time data delivery from GHL to Zapier when events occur.
Trigger onboarding emails when a new contact is added, auto-create follow-up tasks, and tag records for segmentation.
Sync ticket updates from your help desk into GHL and trigger actions in Zapier for status changes.
Aggregate contact data and tasks for real-time revenue dashboards in your BI tool.
Request OAuth credentials from your GHL account and configure the Zapier app to use them.
Complete the OAuth flow in Zapier to authorize access with the required scope: contacts.readonly.
Create a test Zap to fetch contact data and perform actions like tagging or task creation to validate your connection.
The Contacts API integration with Zapier App Connector lets you read and manipulate contact data from GHL through Zapier automations. You can pull contact details, fetch tasks and notes, and trigger actions in response to events. This setup enables powerful no-code workflows between your CRM data and other apps.
You’ll typically need OAuth 2.0 credentials and the contacts.readonly scope at minimum. This ensures Zapier can securely access contact information without granting full write access. Always use the least-privilege scope necessary for your automation.
Common endpoints include GET /contacts/:contactId to retrieve a contact, GET /contacts/:contactId/tasks to list tasks, and POST /contacts/ to create a new contact. Endpoints for notes, tags and updates are also frequently used to enrich automations.
To test, create a small Zap that fetches a contact and creates a sample task or note. Use Zapier’s test feature to verify data mapping and ensure the right fields populate correctly.
Yes. You can use POST /contacts/ to create, and PUT /contacts/:contactId to update, along with POST /contacts/:contactId/tasks to add follow-ups. Ensure your app’s scope allows read and write where needed.
API rate limits depend on your GHL plan. If you exceed limits, you may see 429 responses. Design automations with retries and backoff, and batch requests where possible.
API credentials are issued from your GHL account’s developer or API settings. You’ll configure OAuth client ID and secret in Zapier and request the appropriate scopes (for example, readonly or read/write) during the authorization flow.
Due to high volume, we will be upgrading our server soon!
