How to connect SalesNexus to the GHL Contacts API

GHL Contacts API x SalesNexus: Quick-start integration guide

Steps to connect the GHL Contacts API with SalesNexus

This guide explains how to authenticate, configure endpoints, and leverage key endpoints to sync contacts, tasks, notes, and appointments between the GHL Contacts API and SalesNexus using a secure connection.

Frequently Asked Questions

What authentication method is required for the GHL Contacts API?

GHL supports OAuth tokens or API keys for authenticating requests to the Contacts API. Use a token with the contacts.readonly scope and include it in the Authorization header for every call. Keep tokens secure and rotate them according to your security policy. Ensure your app follows best practices for credential management.

You can access endpoints to retrieve contacts, their tasks, notes, appointments, and related business data. Common paths include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/business/:businessId. Use POST, PUT, and DELETE as needed for create, update, and removal actions on tasks or contacts.

Yes. No-code options are available via pre-built connectors and REST-based workflows. You can configure mappings and triggers without writing code, enabling rapid setup of data flows between GHL and SalesNexus. For advanced use cases, you can extend with custom webhooks or small auxiliary scripts if desired.

Start with a test environment or sandbox. Generate a test OAuth token, call sample endpoints, and verify responses. Monitor sync logs, check for data mismatches, and set alerts for failures to iterate quickly until the integration is stable.

Essential fields typically include contactId, firstName, lastName, email, phone, and related businessId. For tasks and notes, track taskId, noteId, status, and timestamps. Proper mapping ensures clean, consistent data across both systems.

Token rotation should follow your security policy. Store tokens securely, rotate keys periodically, and implement error handling to refresh tokens before expiration. Use least-privilege scopes and monitor access logs for unusual activity.

Yes. The integration can be extended to include business data and appointments by mapping endpoints like GET /contacts/business/:businessId and GET /contacts/:contactId/appointments. This enables a more complete view of relationships and schedules within SalesNexus.
