How to connect Rankr to the Contacts API (GHL API) for Omnisend integration

Seamless GHL Contacts API integration with Rankr

A practical guide to wiring GHL's Contacts API into Rankr

This guide walks you through authenticating, selecting endpoints, and mapping data between GHL and Rankr using the Contacts API. Start by setting up authentication, then create a connection in Rankr, and finally test with a sample contact flow.

Authorization for Contacts API (GHL)

GHL uses API tokens (OAuth 2.0) to authorize requests. Generate or refresh tokens in the GHL developer console and store them securely in Rankr. Use the token in Authorization: Bearer headers for all calls.

Authorization for Rankr App

Rankr authenticates to GHL with OAuth 2.0 client credentials or a service account, depending on your setup. Configure your client ID/secret in Rankr, set the redirect URI, and exchange codes for access tokens to call the GHL API.

Key Contacts API endpoints used with 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

Top 3 connection patterns between GHL Contacts API and Rankr

1) Real-time contact sync

Trigger: when a contact is created or updated in GHL, fetch and sync the record in Rankr to keep data in both systems current.

Actions: GET /contacts/:contactId to retrieve data; POST /contacts/ to create in Rankr if missing; PUT /contacts/:contactId to update; map fields (email, name, phone, tags).

Methods: GET and PUT; endpoint paths from the list above.

Key fields: id, email, firstName, lastName, phone, tags, businessId

2) Task and note alignment

Trigger: on new task or note for a contact in GHL, mirror in Rankr as a related activity.

Actions: GET /contacts/:contactId/tasks and /contacts/:contactId/notes; POST /contacts/ to create tasks/notes in Rankr; update as statuses.

Methods: GET, POST, PUT.

Key fields: taskId, noteId, contactId, status, dueDate, content

3) Tag-based segmentation and business mapping

Trigger: when a tag is added to a contact in GHL, update Rankr segmentation and business mapping accordingly.

Actions: POST /contacts/:contactId/tasks (tag-based workflows) or update contact tags; map to Rankr segments.

Methods: POST, PUT

Key fields: contactId, tags, segments

No-code benefits for GHL Contacts API and Rankr

Faster time-to-value: connect and start syncing data without writing code.

Reduced maintenance: centralized configuration in Rankr keeps endpoints consistent.

Scalability: easily add new endpoints or triggers as your workflows expand.

Three simple steps to connect GHL Contacts API to Rankr

Step 1: Prepare your credentials

Register your app in GHL, obtain client ID/secret, and configure Redirect URI in Rankr.

Step 2: Configure endpoints and mapping

Frequently Asked Questions

Do I need to code to connect GHL Contacts API to Rankr?

No-code options exist via Rankr’s integration builder. You can connect GHL Contacts API with a few clicks and map fields without writing code. If you prefer, code-based routes are available via token-based authentication and standard endpoints. Start with the guided setup in Rankr to see how data flows between systems.

For basic sync, enable endpoints like GET /contacts/:contactId, POST /contacts/, and PUT /contacts/:contactId. Map essential fields such as email, firstName, lastName, and phone. You can expand to tasks and notes as your workflow grows.

Use OAuth 2.0 or API tokens supplied by GHL. Include the Authorization header with Bearer tokens in every request. In Rankr, securely store tokens and refresh as needed.

Yes. Rankr supports mapping custom fields from GHL to Rankr fields. Create field mappings and use transformation rules to align data types and formats.

GHL imposes rate limits. Plan for header-based limits and implement retries with exponential backoff in Rankr.

If a sync fails, check HTTP status codes, verify token validity, inspect request payloads, and review mapping rules. Re-run the sync after fixes.

API credentials and tokens are managed in the GHL developer console. Store them securely and rotate them regularly. In Rankr, reference tokens from a secure vault.
