How to Connect Rankr to the Contacts API

Rankr’s LeadByte integration with the GHL Contacts API

Connecting the Contacts API with Rankr

This guide explains how to authenticate, configure endpoints, and validate the integration between Rankr and the GHL Contacts API for LeadByte.

GHL Contacts API Authentication

Authenticate with OAuth 2.0 to obtain an access token with the scope of contacts.readonly. Include the token in the Authorization header for every request, and ensure your GHL app has the required permissions.

Rankr App Authentication

Rankr authenticates to GHL using OAuth tokens obtained via a secure backend. Store tokens securely, rotate them regularly, and never expose them in client-side code.

GHL Contacts API Endpoints

Endpoints you may use with LeadByte and Rankr 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

Top 3 integration paths between Contacts API and Rankr

1) Retrieve a Contact by ID

Trigger: When a new lead is captured in Rankr, fetch the contact in GHL to sync details.

Actions: Populate Rankr contact fields from GHL contact data and update notes and tasks as needed.

GET /contacts/:contactId

Key fields: contactId, email, name, phone

GET /contacts/:contactId/tasks and GET /contacts/:contactId/tasks/:taskId

Fields: taskId, status, dueDate, title

Actions: Sync notes into Rankr and attach to the appropriate contact’s activity feed.

GET /contacts/:contactId/notes and GET /contacts/:contactId/notes/:id

Fields: id, content, createdAt

No-code benefits of connecting Rankr with the Contacts API

Three Creative Ideas for Integrating the Contacts API with Rankr

Idea 1: Auto-create contacts from new leads

Trigger a real-time flow to create or update a GHL contact whenever Rankr captures a new lead, ensuring both systems stay in sync.

Idea 2: Timeline activity sync

Push tasks, notes, and completed events into a unified activity timeline in GHL from Rankr to provide a complete history.

Idea 3: Custom reports

Aggregate metrics from GHL and Rankr to build cross-system dashboards and reports for executives.

3 Steps to Connect Contacts API with Rankr

Step 1: Authenticate

Obtain OAuth 2.0 tokens for your GHL account and grant Rankr the requested scopes.

Step 2: Configure Endpoints

Choose endpoints (for example, GET /contacts/:contactId and GET /contacts/:contactId/tasks) and map fields to Rankr data.

Step 3: Test & Deploy

Run integration tests to validate data flow, then deploy to production.

Frequently Asked Questions

What’s the difference between reading a single contact and listing all contacts via the API?

Reading a single contact returns the details for that contact, including personal data. Listing all contacts returns a collection that you can paginate, filter, and search. In Rankr, you typically fetch a specific contact to update the CRM person or pull context for an automation. The endpoints you use depend on whether you need a single record or a batch view.

Authentication is via OAuth 2.0. You obtain access tokens using your GHL account credentials and authorize Rankr to access the required scope. Always store tokens securely and include them in the Authorization header for every request. Rotate tokens regularly and follow best security practices.

Useful endpoints for sales workflows include GET /contacts/:contactId, GET /contacts/:contactId/tasks, and GET /contacts/:contactId/notes. Combining these endpoints lets you build a complete view of a contact’s basics, activities, and history within Rankr.

Yes. You can write or update a contact using PUT /contacts/:contactId or POST /contacts/ and related endpoints for tasks and notes. After writing, re-fetch the updated contact to confirm changes and keep data consistent.

Data sync can be near real-time when requests succeed and tokens remain valid; latency depends on network conditions and rate limits. If real-time delivery is critical, consider a polling cadence or batch processing approach to balance load and freshness.

No-code integration is possible for many common use cases using REST endpoints and a builder like Rankr. Coding is only required for custom transformations, complex field mappings, or advanced logic.

Rate limits vary by GHL plan. Start with conservative polling and implement exponential backoff to handle throttling. Refer to the GHL API docs for current quotas and best practices to optimize throughput.
