Use OAuth 2.0 tokens or API keys to authorize requests to the GHL Contacts API on behalf of Rankr.
To access the GHL API from Rankr, configure a client, grant scopes such as contacts.readonly, and securely store your credentials.
1) GET /contacts/:contactId; 2) GET /contacts/:contactId/tasks; 3) GET /contacts/:contactId/tasks/:taskId; 4) GET /contacts/:contactId/notes; 5) GET /contacts/:contactId/notes/:id; 6) GET /contacts/:contactId/appointments; 7) GET /contacts/; 8) GET /contacts/business/:businessId; 9) contacts.write; 10) POST /contacts/; 11) PUT /contacts/:contactId; 12) DELETE /contacts/:contactId; 13) POST /contacts/:contactId/tasks; 14) PUT /contacts/:contactId/tasks/:taskId; 15) PUT /contacts/:contactId/tasks/:taskId/completed; 16) DELETE /contacts/:contactId/tasks/:taskId; 17) POST /contacts/:contactId/tags
Trigger: updates to a contact in GHL trigger a pull to Rankr via GET /contacts/:contactId and related endpoints
Actions: fetch contact, pull tasks, notes, and appointments and create/update in Rankr
Method path: GET /contacts/:contactId
Key fields: id, email, firstName, lastName, phone
Trigger: changes in Rankr update GHL and vice versa
Actions: mirror updates, sync tasks and notes
Method path: PUT /contacts/:contactId
Key fields: id, email, phone, businessId
Trigger: when a task is completed, create a note or update a tag in GHL
Actions: create tag, add note, update status
Method path: POST /contacts/:contactId/tags
Key fields: id, tagId, name
Benefit 1: create powerful automations without writing code
Benefit 2: consolidated view of contacts across platforms
Benefit 3: faster onboarding and outreach through automated tasks
This glossary explains core elements and processes used in the GHL Contacts API integration.
A contact is a person stored in your CRM with identifying details like name, email, and phone
A note is a freeform comment attached to a contact, used for context and history
An endpoint is a URL path to access or modify data in the API
Authentication secures API requests via tokens or keys
Enrich contact records by pulling external data on new contacts
Automatically create onboarding tasks when a new contact is added
Trigger workflows via webhooks on important contact events
In your GHL developer console, generate a client and request the scopes required (e.g., contacts.readonly), then securely store the credentials
Enter the client credentials in Rankr’s integration settings and set up the scope and authentication method
Use the endpoint list to map data fields between Rankr and GHL and run test requests to verify connectivity
The Contacts API scope denotes the access level for reading contact data from GHL into Rankr. Starting with read-only access helps validate data flow before enabling write permissions. You can gradually expand scopes as needed. The integration respects the scope granted and enforces least privilege.
No heavy coding is required for basic integrations; many no-code automation builders or connectors can map fields and trigger actions. For custom logic, light scripting or webhooks can handle edge cases without a full development cycle.
For basic sync, focus on retrieving contacts, notes, tasks, and appointments while mapping key fields. Start with read operations (GET) to verify data accuracy before enabling write endpoints.
Authentication uses tokens or API keys. Store credentials securely and rotate them periodically. Apply least-privilege scopes to minimize risk.
Yes. Rankr can push updates back to GHL using write endpoints such as POST /contacts/:contactId/tasks or PUT /contacts/:contactId to update data.
To test, use sandbox credentials and run sample requests. Verify responses, check logs, and confirm data sync directions between Rankr and GHL.
The endpoint list is provided in the Endpoint List section. Copy it and use it to map fields and validate connectivity.
Due to high volume, we will be upgrading our server soon!
