How to connect GHL Contacts API with Keap

This guide shows how to connect Keap with the GHL Contacts API to sync contacts, tasks, notes, and appointments. It covers authentication, endpoints, and best practices for reliable data flow between Keap and GHL.

Authenticate to the GHL Contacts API using OAuth 2.0 and the scope ‘contacts.readonly’. You will need a client ID, client secret, and a redirect URI from your GHL developer app.

Frequently Asked Questions

Do I need coding to set this up?

No coding is required with the built-in connectors. The guide provides clear, step-by-step instructions to configure the connection using OAuth and field mappings. You can set up a robust integration without writing code. If you want additional customization, you can extend with simple scripts or webhooks as needed.

For an initial sync, focus on core endpoints like GET /contacts/:contactId to retrieve contact data, and GET /contacts/:contactId/tasks to pull related tasks. You may also enable GET /contacts/:contactId/notes and GET /contacts/:contactId/appointments to seed a complete history for each contact. Ensure mapping between Keap’s contactId and GHL’s contactId for accurate linking.

Real-time sync can be near real-time when webhooks are available, but some setups rely on polling intervals defined in your integration platform. Plan for latency based on your provider and API rate limits. Implement retry logic to handle transient errors.

Yes. You can customize field mappings using the UI or a mapping file. Map Keap fields to corresponding GHL fields (e.g., contactId, name, email) and adjust for any custom fields you rely on. Test mappings with sample data.

If a sync fails, check the access tokens and scopes, verify endpoint responses, and review error codes. Use test records to reproduce the failure, then adjust mappings or endpoint selections. Re-authenticate if tokens expire and re-run the sync.

Logs and metrics are available in the GHL API logs section and your integration platform dashboard. Look for request/response details, error messages, and token lifetimes to troubleshoot and optimize performance.
