How to connect Contacts API with Rankr

This guide shows how to authenticate, authorize, and connect the Contacts API (GHL) to Rankr, enabling access to contacts, tasks, notes, and appointments via the API.

Authentication for Contacts API

To access the Contacts API from Rankr, authenticate using an API key or OAuth tokens issued by your GHL instance. Keep credentials secure and grant the minimum required scope (contacts.readonly) for read-only access unless you need write permissions.

Rankr App Permissions

In Rankr, configure the connection by supplying the GHL API base URL, client ID, and client secret (if using OAuth), then authorize Rankr to read contacts, tasks, notes, and appointments as needed.

FAQ

What authentication method should I use?

You can use either API keys or OAuth tokens depending on your setup. API keys are quick for read-only access, while OAuth provides secure, user-consented access with token renewal. Always choose the minimum required scope (e.g., contacts.readonly) to reduce risk. If you’re using OAuth, rotate credentials regularly and store them securely in Rankr.

Essential endpoints typically include GET /contacts/:contactId to fetch details, GET /contacts/business/:businessId to retrieve all contacts for a business, and POST /contacts/ to create new records. Depending on your workflow, you may also use GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes to synchronize related data.

No heavy coding is required if you use Rankr’s built-in connectors and Zapier-style workflows. A basic understanding of REST concepts helps, but most steps involve configuring authentication, selecting endpoints, and mapping fields. Advanced scenarios may require small script steps, but they are optional.

Common contact fields include id, name, email, phone, and tags. You can also access related data such as tasks, notes, and appointments. The exact fields depend on what the GHL API exposes for the Contacts resource.

Yes. You can filter or segment by business using the businessId parameter found in the GET /contacts/business/:businessId endpoint. This helps you scale CRM operations across multiple client companies.

Tasks and notes are retrieved via endpoints like GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes. You can create tasks with POST /contacts/:contactId/tasks and attach notes using POST /contacts/:contactId/notes. Keep data synchronized by updating Rankr records on each change.

If you hit rate limits, stagger requests, implement exponential backoff, and cache non-changing data when possible. Ensure you’re using proper authentication and that your app’s requests align with the API’s rate limits. Monitoring dashboards can help you alert on spikes.
