How to connect Zapier App Connector to Contacts API

Bullhorn CRM integration with the GHL Contacts API via the Zapier App Connector

A straightforward guide to linking the GHL Contacts API with the Zapier App Connector

This guide walks you through connecting the GHL Contacts API to the Bullhorn CRM using the Zapier App Connector. You’ll learn authentication, endpoints, and practical connection patterns to automate contact creation, task management, note capture, and appointment scheduling without writing code.

Authentication for GHL Contacts API

Authenticate securely with the GHL Contacts API using OAuth tokens provisioned through the Zapier App Connector. Ensure your scopes include contacts.readonly for viewing data and the necessary write scopes for updates and creations.

Frequently Asked Questions

What authentication methods are supported?

The integration supports OAuth-based authentication via the Zapier App Connector for secure access to Bullhorn and GHL data. Tokens are refreshed automatically, so you can focus on building your workflows. For advanced users, there are options to use API keys in addition to OAuth depending on your security policies. Always ensure your scopes include read and write permissions appropriate to your use case. In addition, you can rotate credentials on a regular schedule and monitor activity from the Zapier dashboard to maintain security and compliance.

Endpoints include retrieving contacts, tasks, notes, and appointments, as well as creating and updating records. You can review GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and similar endpoints to read data. For writes, use POST /contacts/ to create contacts, PUT /contacts/:contactId to update, and POST /contacts/:contactId/tasks to create tasks. A complete list lives in the Endpoints section of the app connector.

No extensive coding is required. The Zapier App Connector provides a no-code interface to map fields, set triggers, and define actions between GHL and Bullhorn. For complex logic, you can still customize steps with conditional paths and multi-step workflows using Zapier’s built-in features.

Rate limits are governed by the Bullhorn API and the GHL integration. Zapier will queue and retry requests according to standard retry guidelines. If you anticipate high-volume usage, consider batching requests and staggering workflows to avoid hitting limits.

Yes. You can sync notes and appointments by using triggers on note or appointment changes and corresponding actions to create or update records in the other system. This ensures activity history stays aligned across platforms.

Use the Connect/Test feature in the Zapier App Connector to verify authentication and field mappings. You can run a test workflow to simulate data flow and confirm that records are created, updated, and linked correctly.

Endpoint documentation is available within the Zapier App Connector’s help section and the Bullhorn API docs. You can also consult the Endpoints list in the Bullhorn connections template for quick reference to each available operation.
