Access to the Contacts API requires OAuth 2.0 authentication with the scope ‘contacts.readonly’ to read contact details and related resources.
Google Tasks authentication uses OAuth 2.0 and Google API credentials; ensure the Tasks API is enabled and the app has the necessary scopes to create or update tasks.
Primary endpoints used include GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, GET /contacts/:contactId/notes, and related endpoints to read, create, update notes and to manage contact data.
Trigger: When a contact is created or updated in Contacts API, create or update a matching task in Google Tasks.
Actions: Create a task, set the title from the contact name, assign due date, attach notes, and link the contact record.
Method path: GET /contacts/:contactId to fetch data; POST /contacts/:contactId/tasks to create tasks; PUT /contacts/:contactId/tasks/:taskId to update.
Key fields: contactId, taskId, status, dueDate, notes.
Trigger: A task is updated in Google Tasks or a contact field changes in Contacts API.
Actions: Propagate changes to the other system, updating the task or contact notes accordingly.
Method path: POST /contacts/:contactId/tasks to create or PUT /contacts/:contactId/tasks/:taskId to update; use webhooks to sync updates.
Key fields: contactId, taskId, status, lastSynced.
Trigger: New or updated contact data triggers a reminder task in Google Tasks.
Actions: Create reminder tasks with due date and notes; update or complete as needed.
Method path: POST /contacts/:contactId/tasks to create reminders; PUT /contacts/:contactId/tasks/:taskId to adjust.
Key fields: contactId, taskId, dueDate, reminderNotes.
Automate repetitive tasks without writing code.
Keep teams in sync by automatically creating and updating tasks from contact data.
Scale workflows quickly with prebuilt triggers and endpoints.
This glossary defines API, endpoint, trigger, action, and OAuth 2.0 as used in the GHL Contacts API to Google Tasks integration.
A set of endpoints that allow software to interact with a service.
An authorization framework that lets apps gain limited access to user data without exposing credentials.
A specific URL path in an API that performs a defined action.
An event that starts an automated workflow in an app.
When a new contact is added in Contacts API, automatically generate a task in Google Tasks with a follow-up date.
Update related tasks when contact data changes; keep notes synchronized.
Use contact segments to tag tasks for team assignment and prioritization.
Create OAuth credentials for both APIs and authorize access with scopes: contacts.readonly and Google Tasks scope.
Define field mappings between contacts and tasks and connect endpoints like GET /contacts/:contactId and POST /contacts/:contactId/tasks.
Run tests, verify data, set retries, monitor logs.
No code is required for this setup. The integration uses the visual editor in GHL to configure triggers, actions, and mappings, so you can connect Google Tasks to the Contacts API without writing any scripts. You can customize fields and flows to fit your workflow. If you need more advanced logic, you can add webhooks or additional endpoints to extend capabilities.
Key endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, and PUT /contacts/:contactId/tasks/:taskId/completed. Additional endpoints handle notes and contact updates. These endpoints enable reading contact data, creating and updating tasks, and tracking task status.
The required scope for reading contact data is contacts.readonly. You may request additional scopes if you need write access to tasks or notes. Keep permissions minimal to reduce risk and review what the app can do during OAuth consent.
Yes. You can configure the integration to read data only, so no writes occur in Google Tasks or Contacts API. If you need to create or update tasks, you will require write access for tasks.
Use the built-in test flows in GHL to simulate a contact update and verify that the corresponding task is created or updated in Google Tasks. Check activity logs for errors and adjust mappings as needed.
If a contact is deleted, you can choose to skip, archive, or soft-delete related tasks depending on your workflow. Ensure your data retention and cleanup policies align with your business needs.
Endpoint documentation is available in your API developer portal and in the GHL connectors section within the app. You can reference endpoints like /contacts, /contacts/:contactId, and /contacts/:contactId/tasks for how the integration works.
Due to high volume, we will be upgrading our server soon!
