Authenticate requests with a valid API token from the GHL portal and include your Rankr client credentials in each call.
In Rankr, store your API key securely and pass it in the Authorization header when calling the Contacts API endpoints.
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: retrieve a contact by ID to populate profiles, notes, and tasks in Rankr.
Actions: fetch core contact fields, pull related notes and tasks, and sync the contact record.
GET /contacts/:contactId
Key fields: id, firstName, lastName, email, phone, customFields
Trigger: fetch a list of contacts to seed dashboards.
Actions: return a paginated set of contacts with basic identifiers.
GET /contacts/
Key fields: id, name, email, status, lastActivity
Trigger: create a contact record in Rankr when a new contact is added in GHL.
Actions: send create request to /contacts with payload, then return the new contact id.
POST /contacts/
Key fields: firstName, lastName, email, phone, tags, customFields
Rapid integration without writing code, using Zapier as a bridge.
Unified data flow: sync contacts, notes, tasks, and appointments in one place.
Scalable automations with reusable templates and triggers.
A quick glossary of the terms used in this guide, including API endpoint, authentication, CRUD, and triggers.
An API endpoint is a specific URL that performs a defined operation, such as retrieving a contact or creating a task.
Authentication proves who you are and allows access to GHL resources. Use tokens or OAuth.
CRUD stands for Create, Read, Update, Delete—the core operations used to manage data via REST APIs.
Rate limiting controls how many requests you can make in a given time to protect the API from abuse.
When a new contact enters GHL, automatically pull notes and recent tasks into Rankr to create a richer profile.
Use triggers on contact updates to create follow up tasks and route to the right owner in Rankr.
Sync appointments from GHL into Rankr and send reminders via Rankr workflows.
Generate an API key in the GHL portal for Contacts API and add Rankr as a connected app; store the key securely.
Select the endpoints you need such as GET /contacts/:contactId and GET /contacts/; set up required fields.
Test in a sandbox environment, verify data mapping, then deploy to production.
You can authenticate via API tokens issued in the GHL portal and pass them in the Authorization header. For added security, bind Rankr to a dedicated app credential and rotate keys regularly. If your organization uses OAuth, follow the standard OAuth flow to obtain access tokens and refresh tokens. Always use HTTPS to protect data in transit. Finally, review permissions to ensure only required scopes are granted.
Start with the core read endpoints like GET /contacts/:contactId to populate profiles and then extend to fetch tasks and notes with GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes. This gives a solid data foundation for dashboards and automation. As you expand, you can add endpoints for creating or updating records, such as POST /contacts and PUT /contacts/:contactId.
Yes. Use GET /contacts/:contactId/tasks to retrieve tasks related to a contact and GET /contacts/:contactId/notes to pull notes. You can also fetch appointments with GET /contacts/:contactId/appointments. Combining these endpoints lets Rankr present a complete picture of activity for each contact.
To create a contact, send a POST to /contacts/ with a payload that includes required fields such as firstName, lastName, and email. Ensure you map custom fields as needed. The response will include the new contact ID which you can use in subsequent calls to attach tasks or notes.
There is a rate limit in place to protect the API. If you exceed it, you will receive a 429 response. Plan requests with pagination for large data sets and implement retries with exponential backoff. Monitor your usage in the GHL portal and adjust as needed.
Store API keys securely using a secrets manager and restrict access to trusted services. Rotate keys on a regular schedule and audit access logs. Use least privilege by granting only the necessary scopes for Rankr to function. Enable IP allowlisting if available.
Yes, deleting a contact is possible via DELETE /contacts/:contactId. Consider soft deletes or archiving when appropriate. Always back up data before deletion and ensure dependent records such as tasks and notes are handled according to your data retention policies.
Due to high volume, we will be upgrading our server soon!
