Choose an authentication method (API key or OAuth) to securely access the Contacts API endpoints.
Rankr will authenticate with GHL using OAuth 2.0 or API tokens, with least-privilege scopes.
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 contact is needed in Rankr, fetch from GHL.
Actions: Call GET /contacts/:contactId to pull details; use GET /contacts/ to list; map fields (name, email, phone) to Rankr records.
GET /contacts/:contactId
Key fields: contactId, email, name
Trigger: After retrieving a contact, sync its tasks.
Actions: GET /contacts/:contactId/tasks; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed
GET /contacts/:contactId/tasks; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed
Key fields: contactId, taskId, status
Trigger: When notes or tags change in Rankr, update GHL.
Actions: GET /contacts/:contactId/notes; POST /contacts/:contactId/notes; POST /contacts/:contactId/tags; GET /contacts/:contactId/notes/:id
GET /contacts/:contactId/notes; POST /contacts/:contactId/notes; POST /contacts/:contactId/tags
Key fields: contactId, noteId, tag
No-code automation saves time by syncing data without custom scripts.
Real-time data sync reduces manual entry and errors.
Scoped access via contacts.readonly helps maintain security while enabling essential workflows.
Key elements include endpoints, authentication, field mappings, and data flows for a successful GHL-Rankr integration.
The process of verifying identity to access the API, typically via OAuth 2.0 or API keys.
A specific URL path that performs an action or returns data from the API.
GET, POST, PUT, DELETE indicate the operation requested on a resource.
The process of obtaining and refreshing access tokens to authenticate API requests.
Automatically create Rankr contacts in GHL when a new lead enters Rankr.
Push task updates from Rankr to GHL and reflect status changes.
Attach notes and tags to contacts automatically based on Rankr events.
Obtain API key or OAuth client credentials for both Rankr and GHL and set permissions.
Configure OAuth flow or token exchange and test access to endpoints.
Define mappings between Rankr fields and GHL contact fields and validate all endpoints.
The GHL Contacts API exposes a range of endpoints to read and manage contacts, tasks, notes, appointments, and tags. Use GET endpoints to retrieve data and POST/PUT/DELETE where you have write permissions. Ensure your app has the appropriate scopes (for example, contacts.readonly vs. contacts.write).
To authenticate from Rankr, configure OAuth 2.0 or API key flows within your app settings, generate credentials, and include them in requests. Keep tokens secure, rotate keys regularly, and follow least-privilege principles.
Yes, you can read and write contacts if your app is granted the write scope (contacts.write). If you only need read access, use the readonly scope to protect data while enabling viewing capabilities.
Test endpoints in a staging or sandbox environment before connecting to live data. Use sample IDs and mock responses to verify field mappings and error handling without impacting real records.
Store tokens securely, use encrypted transmission (HTTPS), and rotate credentials regularly. Implement audit trails for data changes and validate mappings to prevent data corruption.
Webhooks are not covered in this guide. For real-time updates, you can rely on polling or Rankr automation to trigger actions when data changes occur. Refer to your GHL provider docs for webhook availability.
Endpoint usage guidance is included in the endpoint list and mapping sections. For deeper details, consult the developer docs and the example workflows provided in this guide.
Due to high volume, we will be upgrading our server soon!
