To access the Contacts API, obtain OAuth credentials for the GHL app and request the scope contacts.readonly. Use the access token to authenticate API calls when calling endpoints like GET /contacts.
Authorize APPNAME to receive data from GHL by configuring a secure OAuth flow or API key depending on APPNAME capabilities. Ensure redirection URLs and scopes are set correctly.
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 when a new contact is created in APPNAME or when existing contact data changes; ensure idempotent operations.
Actions include creating a new contact via POST /contacts/ and updating via PUT /contacts/:contactId; optional tagging.
Methods and paths: POST /contacts, PUT /contacts/:contactId
Key fields include name, email, phone, company
Trigger on task events in APPNAME to reflect in GHL via POST /contacts/:contactId/tasks or PUT updates.
Actions: POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId
Endpoints for tasks: POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId
Fields: taskId, title, status, dueDate
Trigger when notes are added or updated in APPNAME to create or update notes in GHL via POST /contacts/:contactId/notes
Actions: POST /contacts/:contactId/notes, GET /contacts/:contactId/notes, DELETE /contacts/:contactId/notes/:id
Note related endpoints include POST /contacts/:contactId/notes
Fields: id, content, author, createdAt
No code automation enables teams to connect data flows without writing custom integration code.
Unified contact data across APPNAME and GHL helps run smarter marketing and sales workflows.
Prebuilt endpoints and triggers reduce maintenance and speed up time to value.
Key elements include API Endpoints, Triggers, Actions, Methods and Key Fields. Understanding these helps design reliable integrations.
A URL path used to access a specific resource in an API.
The process of proving identity and obtaining access tokens to call APIs securely.
An event that initiates a workflow or automation in response to a change in data.
An operation performed by the system in response to a trigger, such as create or update.
Set a scheduled daily sync in the integration to keep contact data up to date without manual input.
Mirror tasks and notes between APPNAME and GHL to provide a 360 degree view.
Update audience segments in real time when contacts change in either system.
Create an app in GHL and obtain an access token with the scope contacts.readonly.
Configure webhooks and triggers in APPNAME to call GHL endpoints when data changes.
Map fields such as name email phone to GHL fields and run tests.
Yes you can set this up with little to no coding by using integration tools like Zapier or built in connectors. These tools provide drag and drop mapping and prebuilt actions for common endpoints. For more reliability, some familiarity with REST APIs and authentication flows helps you troubleshoot issues quickly.
For basic sync start with GET /contacts/:contactId to pull contact data and POST /contacts/ to create entries. This establishes a simple one way sync. You can also list contacts with GET /contacts to map fields and test. As you mature your setup, add PUT and DELETE calls to handle updates and removals.
Authenticate using OAuth 2.0 and obtain an access token with the required scopes. Store the token securely and refresh as needed. Ensure the token includes the correct scope such as contacts.readonly to perform the intended actions.
Yes you can update existing contacts using PUT /contacts/:contactId after matching the contact by id. Use idempotent requests and handle conflicts gracefully to prevent duplicate records.
API rate limits apply. Monitor rate limit headers and implement retry logic with backoff. If your workflow requires high volumes, consider batching requests where supported.
Notes and tasks can be retrieved with GET endpoints and created or updated with POST and PUT calls. This enables a complete activity history per contact and supports workflow automation.
Refer to the official GHL Contacts API docs for endpoint specifics, authentication flows and payload examples. If you need further help, contact support or your integration partner.
Due to high volume, we will be upgrading our server soon!
