Access to the Contacts API is controlled via OAuth 2.0. Obtain a token with the proper scopes and include it in your requests.
Configure Rankr to request an access token from GHL, then store and securely refresh it as needed.
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: A contact is created or updated in GHL.
Actions: Fetch the contact data via GET /contacts/:contactId, map fields (name, email, phone), and push updates into Rankr.
GET /contacts/:contactId
contactId, firstName, lastName, email, phone
Trigger: A new task is created in GHL for a contact.
Actions: Use POST /contacts/:contactId/tasks to create a task in Rankr and sync status.
POST /contacts/:contactId/tasks
contactId, taskTitle, dueDate
Trigger: Notes or appointments are added or updated in GHL.
Actions: Retrieve GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments and attach to the Rankr contact profile.
GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments
contactId, appointmentId, noteId

This glossary defines core concepts and processes used in connecting GHL’s Contacts API with Rankr, including endpoints, authentication, and data mapping.
API stands for Application Programming Interface. It exposes endpoints you can call to read or modify data.
An endpoint is a specific URL in an API that performs a function or returns data.
Authentication verifies identity and grants access tokens to call protected endpoints.
Rate limiting restricts how many requests you can make within a time window to protect the service.
Push changes from GHL to Rankr as they happen to keep contact records current.
Create and assign tasks in Rankr when tasks are updated in GHL.
Consolidate notes from GHL into Rankr to enrich contact histories.
Register the Rankr app in GHL’s developer portal to obtain client credentials.
Set scopes to include read/write access as needed and configure your callback/redirect URLs.
Run test calls to retrieve a contact, verify data mapping, and monitor for errors before going live.
The Contacts API is a RESTful interface that lets your app read, create, update, and delete contact data in GHL. Use standard HTTP verbs to perform operations and receive structured responses.
Requests are authenticated using OAuth 2.0. You obtain an access token and include it as a Bearer token in the Authorization header. Refresh tokens as needed and keep tokens secure on your server.
Endpoints include reads like GET /contacts/:contactId, as well as create, update and delete operations such as POST /contacts/ and PUT /contacts/:contactId. The full list in this guide shows common endpoints used in Rankr integrations.
Yes, several endpoints support write operations (POST, PUT, DELETE) such as creating contacts, updating details, or deleting records. Ensure your app has the required scopes and test changes in a sandbox first.
The API enforces rate limits. Plan requests, implement exponential backoff, and respect the rate limit headers. If you hit a limit, retry after the recommended window and monitor quotas.
If you see an error, check the HTTP status code and the error payload for details. Common issues include invalid tokens, expired tokens, insufficient scopes, or wrong endpoints; fix and retry.
Official docs, developer portal, and community forums are valuable resources. For tailored assistance, contact Rankr support or your GHL account manager.
Due to high volume, we will be upgrading our server soon!
