To call the Contacts API, obtain an OAuth 2.0 access token from your GHL developer console with the required scopes. Use the token in the Authorization header for every API call. For read-only work, use the contacts.readonly scope; for modifications, use the appropriate write scopes (e.g., contacts.write).
Register Rankr as an application in your GHL developer portal to receive client credentials. Exchange authorization codes for tokens, securely store them, and refresh tokens as needed. Use the access token to authorize API requests from Rankr.
– 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 updated in GHL; fetch details and related tasks to surface in Rankr.
Actions: GET /contacts/:contactId, GET /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, POST /contacts/:contactId/tasks
GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId
Required fields: contactId, token; optionally taskId when updating.
Trigger: a new note or appointment is created for a contact.
Actions: GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments
GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments
contactId
Trigger: a new contact is added in Rankr.
Actions: POST /contacts/, POST /contacts/:contactId/tags
POST /contacts/, POST /contacts/:contactId/tags
Required: name, email; auth token; tag names

Sync notes and tags to keep CRM data consistent across apps.
Register Rankr in the GHL developer console and obtain client credentials (client_id and client_secret).
Select relevant scopes such as contacts.readonly and contacts.write, then complete the OAuth flow to obtain tokens.
Test API calls in a sandbox, handle token refresh, and deploy to production.
The Contacts API exposes endpoints to read and manage contacts, tasks, notes, appointments, and tags. Use GET calls for retrieval, POST for creation, PUT for updates, and DELETE for removals. Refer to the endpoint list to map data and actions to your Rankr workflows. Always test endpoints in a sandbox to confirm payloads and responses before production use.
Yes. To write data (create, update, delete), you must request write scopes such as contacts.write in addition to read-only scopes. Your OAuth token must include the necessary scopes for the actions you intend to perform. If needed, re-authenticate to grant new scopes.
GHL uses OAuth 2.0. In Rankr, you initiate the OAuth flow from the developer console, obtain an authorization code, exchange it for access and refresh tokens, and include the access token in Authorization headers for API calls. Securely store tokens and rotate credentials periodically.
Yes. You can tag existing contacts via POST /contacts/:contactId/tags, enabling dynamic categorization. Tagging supports segmentation and downstream automation in Rankr.
Begin in a sandbox environment to validate API calls, payload mappings, and error handling. Use sample data for creates and updates, then verify responses and data integrity before going live.
Expect standard API rate limits; implement retries with exponential backoff and plan token refresh to avoid interruptions. Monitor logs, set alerts for failures, and optimize request payloads and frequency.
Refer to the GHL API developer docs for endpoint references, authentication guides, and payload examples. For further help, use the support channels in the GHL developer portal or Rankr documentation.
Due to high volume, we will be upgrading our server soon!
