Authenticate using OAuth 2.0. Obtain an access token by exchanging your client_id and client_secret for a Bearer token, then include it in the Authorization header for each call. The defined scope is contacts.readonly by default.
To connect Rankr to GHL, register Rankr in the GHL developer portal, capture the client_id and client_secret, configure redirect URLs, and securely store tokens in Rankr.

Trigger: when a contact is created or updated in GHL
Actions: pull changes into Rankr, update or create the corresponding contact, and attach related tasks or notes as needed.
Recommended methods: GET for reads; POST/PUT/DELETE for writes within the allowed scope (use endpoints 1-17 above).
Key fields: contactId, taskId, noteId, businessId
Trigger: scheduled jobs or manual import/export
Actions: bulk create/update of contacts via POST /contacts/ and PUT /contacts/:contactId; assign tags and related tasks in batch.
Endpoints commonly used: POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks.
Key fields: contactId, businessId, tag, taskId
Trigger: based on contact attributes or tag changes
Actions: automatically create or update tasks (endpoints 13-16), mark tasks completed (15), and link notes (4-5) as part of a workflow.
Faster onboarding with ready-made connectors and templates.
Centralized data access across GHL and Rankr, reducing data silos.
Automated workflows cut manual data entry and errors.
This glossary covers endpoints, triggers, actions, methods, and key fields used in the Rankr–GHL Contacts API integration.
GHL refers to the API environment exposed by the platform to access contact data and related resources for integration.
A specific path and HTTP method used to access a resource via the API.
OAuth 2.0 is the authorization framework used to obtain access tokens for API calls.
A callback URL used to receive event notifications from the API.
Enrich contact records by pulling additional data sources and appending notes or tags in Rankr.
Automatically generate tasks and reminders when contact attributes change.
Create targeted campaigns in Rankr based on contact segmentation from GHL.
Register Rankr as an app in the GHL developer portal to receive a client_id and client_secret, and configure redirect URIs.
Enter the redirect URI in the GHL app settings, select the required scopes (including contacts.readonly), and test the flow.
Run end-to-end tests, validate data sync, and enable production deployment with monitoring.
The Contacts API lets Rankr access and manage GHL contact data within your workflows, enabling richer customer experiences. Use the read-only scope for everyday data reads; for writes, request elevated permissions and ensure proper security.
No heavy coding is required thanks to prepared endpoints and connectors. Leverage webhooks or browser automation for common tasks without backend development.
Core endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and related paths as listed in the docs. The endpoint list on this page covers the suite; you can assemble them to build workflows.
Authenticate via OAuth 2.0; obtain an access token using your client_id and client_secret. Pass the token in the Authorization header as Bearer
Handle errors with HTTP status codes and API-provided messages. Implement retries with exponential backoff and monitor quotas to maintain reliability.
Yes, you can sync tasks, notes, and appointments using the relevant endpoints. Ensure proper permissions and test thoroughly to avoid data drift.
There are rate limits and quotas for API calls. If you approach the limit, back off and stagger requests, or contact support for higher limits if warranted.
Due to high volume, we will be upgrading our server soon!
