Use OAuth 2.0 with the scope set to contacts.readonly and keep your credentials secure. You’ll authorize Rankr to access contact data on your behalf.
Configure OAuth credentials in Rankr and connect them to the Contacts API to enable secure, token-based access.
Key endpoints include 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 specific contact is requested by ID or when contact data changes.
Actions: fetch details from Contacts API and sync to Rankr contact profile.
GET /contacts/:contactId
contactId, include or fields parameters
Trigger: need to import or refresh full contact list.
Actions: retrieve /contacts/ and batch update records in Rankr.
GET /contacts/
N/A
Trigger: a new or updated task on a contact.
Actions: create or update tasks via Contacts API and reflect status in Rankr.
POST /contacts/:contactId/tasks
contactId, taskId (for updates)
Automate data sync and workflows without writing custom code.
Create a single source of truth for contacts, notes, and tasks across tools.

A concise glossary of the API terms used throughout this guide to help you implement quickly.
A specific URL and HTTP method that enables a request for data or an action on a service.
An authorization framework that grants tokens after user consent, enabling secure API access.
The process of verifying identity and granting access to resources.
The URL path used to reach a resource, including any parameters.
Push changes from GHL to Rankr instantly to keep contact data fresh.
Automatically create and assign tasks in Rankr when notes or events occur in GHL.
Combine Contacts data with Rankr dashboards for a unified view of customer interactions.
Register the app in GHL, capture client_id and client_secret, and request the scope: contacts.readonly.
Set up Rankr to receive event payloads from GHL, and map fields within Rankr.
Run end-to-end tests, validate data mappings, and monitor for errors once deployed.
The Contacts API uses OAuth 2.0 with access tokens and scopes. Use your client_id and client_secret to obtain a token, then authorize Rankr to read contact data. Ensure tokens are stored securely and refreshed as needed.
Core endpoints include GET /contacts/:contactId and GET /contacts/. For typical read tasks you’ll also use GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/business/:businessId. For modifications, you’ll rely on POST, PUT, or DELETE variants. Test against a sandbox and validate response handling.
Expect rate limits; implement exponential backoff retries and respect retry-after headers. When batches are supported, group requests to minimize round-trips while avoiding timeouts.
Bidirectional sync is possible but requires careful field mapping and conflict resolution rules. Prefer a single source of truth and use webhooks to push updates where possible.
No heavy coding is required; many integrations can be configured with in-app actions and data mappings. Some scenarios may benefit from lightweight automation scripts or rules.
Use a staging environment with test credentials and sample payloads. Validate mappings, run end-to-end tests, and monitor logs and alerts before going live.
Official API documentation is available in the GHL Developers portal and in Rankr’s integration docs. If something is unclear, contact support for guidance.
Due to high volume, we will be upgrading our server soon!
