Authenticate to the GHL Contacts API using OAuth 2.0 Bearer tokens with the scope contacts.readonly. Request credentials from your GHL admin and configure them in the Zapier App Connector.
In the Zapier App Connector, set up OAuth 2.0 using your app’s client ID and secret. Authorize the connector to access your GHL Contacts API data and securely store tokens.
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: Need to look up a contact by ID to pull the latest data into a workflow.
Actions: Get contact data; fetch related tasks, notes, and appointments.
Method path: GET /contacts/:contactId
Key fields: contactId, name, email
Trigger: New lead captured in Convoso flows.
Actions: Create contact (POST /contacts/), optionally attach tasks or notes.
Method path: POST /contacts/
Key fields: name, email, phone
Trigger: Task creation or update in one system triggers actions in the other.
Actions: Create or update tasks (POST /contacts/:contactId/tasks or PUT /contacts/:contactId/tasks/:taskId); mark completed (PUT /contacts/:contactId/tasks/:taskId/completed).
Method path: PUT /contacts/:contactId/tasks/:taskId
Key fields: taskId, status, dueDate
Automate data flows without writing code, using Zapier to orchestrate GHL Contacts API actions.
Create end-to-end workflows that trigger on contact changes, tasks, notes, and appointments.
Centralize error handling and logging within Zapier run histories for auditing.
Brief definitions of core concepts and how they relate in this integration, including terms like Contact, API Endpoint, OAuth 2.0, and Scope.
A contact is a person stored in GHL with fields such as name, email, phone, and related records like tasks, notes, and appointments.
A URL path that enables a specific operation (GET, POST, PUT, DELETE) against the GHL API.
OAuth 2.0 is an authorization framework used to grant limited access to resources securely without sharing credentials.
A set of permissions granted to the app, such as contacts.readonly, controlling what actions are allowed.
Pull external data or notes into contact records when new contacts are created to enrich CRM data.
Automatically propagate tasks or notes between Convoso events and GHL to keep teams aligned.
Use a batch process to update multiple contacts from CSV and create related items in one flow.
In GHL, create OAuth client or API key with the required scope (contacts.readonly) to authorize Zapier.
Enter the client ID/secret, set the base API URL, and test the connection to ensure tokens are valid.
Run a test Zap to verify data flow, handle errors, and then deploy to production.
Yes. No code is required to connect the GHL Contacts API with the Zapier App Connector. Use Zapier’s triggers and actions to view, search, and fetch contact data. You can also set up simple automations that pull data into other apps without writing any code. Keep credentials secure by using Zapier’s built-in credential storage and encryption.
The required scope is typically contacts.readonly for read-only operations. If you need to create or modify data, you must enable write privileges in your GHL OAuth configuration. Always follow the principle of least privilege and request only the scopes you need for your workflow.
Endpoints range from reading a contact to managing tasks, notes, and appointments. For example, GET /contacts/:contactId retrieves a contact, POST /contacts/ creates one, and PUT /contacts/:contactId updates it. Write operations require appropriate authorization and the correct scope.
Yes—if allowed by your credentials and scope, you can create, update, or delete contacts via the API. In Zapier, you would configure the corresponding actions to perform these operations as part of your Zap. Ensure you have the necessary permissions before enabling write operations.
Authentication is handled via OAuth 2.0. You’ll obtain a client ID and secret, request an access token, and store it securely in Zapier. Tokens should be refreshed automatically, and you should monitor for expiration and revocation events.
Due to high volume, we will be upgrading our server soon!
