Authenticate requests using OAuth 2.0 tokens scoped to contacts.readonly. Retrieve tokens from your GHL developer app and refresh them regularly.
Authorize Rankr to access GHL data via an API key or OAuth credentials. Store tokens securely and rotate credentials per security best practices.
GET /contacts/:contactId — Retrieve a single contact; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task; GET /contacts/:contactId/notes — Get notes for a contact; GET /contacts/:contactId/notes/:id — Retrieve a specific note; GET /contacts/:contactId/appointments — Fetch appointments for a contact; GET /contacts/ — List contacts; GET /contacts/business/:businessId — List contacts by business; API Endpoint9: contacts.write — Write access to contacts; POST /contacts/ — Create a new contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Remove a contact; POST /contacts/:contactId/tasks — Create a new task for a contact; PUT /contacts/:contactId/tasks/:taskId — Update a task; PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task complete; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Add tags to a contact
Trigger: When a new contact is created in Rankr, fetch its full profile from the GHL Contacts API.
Actions: Pull core fields such as name, email, and phone; pull notes and related tasks to build a complete contact profile.
GET /contacts/:contactId
contactId, name, email, phone, ownerId
Trigger: When a task is created or updated for a contact in GHL.
Actions: List tasks, update status, and reflect changes in Rankr dashboards.
GET /contacts/:contactId/tasks
contactId, taskId, title, status, dueDate
Trigger: When notes are added or updated in GHL for a contact.
Actions: Retrieve notes, create notes, and sync to Rankr notes feed.
GET /contacts/:contactId/notes
contactId, noteId, content, createdAt
No custom code is required—achieve fast, reliable data sync between Rankr and the GHL Contacts API.
Automations trigger CRM actions without writing scripts, reducing maintenance time.
Unified customer records across Rankr and GHL give your team better context for outreach.
This glossary defines authentication, endpoints, resources, rate limits, and webhooks used in this guide to help non-technical readers.
The process of proving identity and obtaining access tokens to call the GHL API from Rankr.
A specific URL and HTTP method used to perform an action against the GHL API.
OAuth 2.0 access tokens or API keys used for authorization.
Maximum number of API requests allowed in a given time window.
Set up an onboarding flow where new leads in Rankr automatically create or update contacts in GHL and initialize related tasks.
As tasks move in GHL, Rankr updates progress dashboards and triggers follow-up actions.
Aggregate notes from GHL into Rankr for a single, searchable customer context.
In your GHL developer console, create an API key and an OAuth client to authorize Rankr.
Grant Rankr permissions for contacts.readonly and obtain tokens for continuous access.
Set up webhooks for contact events and run end-to-end tests to verify data flow.
You will authenticate using OAuth 2.0 tokens issued by GHL and scoped to the Contacts API. Create a GHL developer app and exchange client credentials for access tokens. Tokens should be stored securely and refreshed before expiration. Implement token refresh logic to maintain uninterrupted access.
Common endpoints for syncing include GET /contacts/:contactId to fetch contact data and GET /contacts/:contactId/tasks to pull related tasks. Depending on needs, you may fetch notes with GET /contacts/:contactId/notes. Use batch or bulk operations where supported to minimize calls and maximize efficiency.
GHL enforces rate limits to protect the API. Plan for bursts by batching requests and handling 429 responses with exponential backoff. To reduce polling, consider using webhooks for event-driven updates where possible.
Yes. Rankr can create and update contacts and tasks using POST, PUT, and DELETE calls such as POST /contacts/ and PUT /contacts/:contactId/tasks/:taskId. Ensure your integration has the necessary permissions and that operations are idempotent where feasible.
GHL provides development and sandbox environments for testing. Use test tokens and representative data to validate flows without affecting production records. Always verify in a staging environment before going live.
When errors occur, log the status code and message, implement exponential backoff, and retry idempotent operations. If issues persist, consult the GHL developer docs and support resources to diagnose permission or endpoint issues.
Official GHL API documentation is available in the GHL developer portal. Look for the Contacts API reference, authentication guides, and example requests. Use these resources to tailor Rankr’s calls to your workflow.
Due to high volume, we will be upgrading our server soon!
