Learn how to securely authorize your GHL app to access Contacts API data using OAuth 2.0 scopes such as contacts.readonly. This ensures safe, auditable access to contact data.
Grant permission for your Google account to share contact data with the integration. You’ll complete this via OAuth consent screens during setup.
– 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 – WRITE: 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 updated in Google Contacts, propagate changes to the Contacts API.
Actions: fetch contact data, create or update the corresponding contact in Contacts API, and optionally push changes back to Google Contacts.
GET /contacts/:contactId
Key fields: id, name, email, phone
Trigger: a new task is created under a contact in Contacts API.
Actions: create/update tasks in Contacts API and reflect status in Google Contacts; attach to contact.
POST /contacts/:contactId/tasks
Fields: contactId, taskId, title, dueDate, status
Trigger: notes are added or updated on a contact in Google Contacts.
Actions: create notes in Contacts API; update Google Contacts notes; apply tags.
PUT /contacts/:contactId/notes/:id
Fields: contactId, noteId, content
No-code automation to save time and reduce manual data entry.
Real-time data sync to keep contact records consistent across platforms.
Centralized view of contact data and activities from Google Contacts and Contacts API.
This glossary covers core terms like Authentication, Endpoint, Contact, Webhook, and common data processes such as sync, triggers, and CRUD operations.
OAuth 2.0 based authorization to securely connect Google Contacts and the Contacts API.
A URL path that performs a specific action or retrieves data from an API.
An individual person stored in Google Contacts and synchronized with the Contacts API.
A callback endpoint that receives event notifications from the connected services.
Automatically tag imported contacts based on attributes to improve segmentation.
Consolidate notes into the Contacts API for a complete contact timeline.
Automatically create tasks in the Contacts API when calendar events occur and mirror status.
Set up OAuth credentials and consent screens for both services.
Select endpoints: read, write, and task/note actions.
Run tests, verify data sync, and set up alerts.
No coding is required thanks to a no-code style setup that guides you through the connection. If you want more control, you can map fields and triggers visually to tailor the sync between Google Contacts and the Contacts API.
For a basic sync, focus on reading data with GET endpoints like GET /contacts/:contactId and GET /contacts to pull contacts, notes, and tasks. For writing, use POST, PUT, and DELETE operations to create or update contacts, tasks, and notes. Enable endpoints for notes and tasks and consider webhooks for near real-time updates.
OAuth 2.0 is used to authorize access. You will exchange client credentials for access tokens and scope what the app can read or write. Store tokens securely, refresh before expiry, and follow least privilege practices.
Yes, you can update Google Contacts from the Contacts API provided you have the proper write permissions and field mappings. Some fields may require transformation to match Google Contacts formats.
Common fields include id, name, email, phone, and tags; notes and tasks are also synced. Mapping is required as data models differ between services.
Rate limits depend on your plan and the API you’re calling. Expect quotas for reads and writes. Implement retry with backoff and consider batching for efficiency.
Endpoint documentation is in the developer portal for the Contacts API integration with Google Contacts. If you cannot find it, contact support for the latest docs and examples.
Due to high volume, we will be upgrading our server soon!
