Frequently Asked Questions

Do I need a developer to connect the Contacts API with Zapier App Connector?

No deep coding skills are required. Zapier App Connector provides a visual interface to connect GHL’s Contacts API endpoints to your apps. If you have basic familiarity with APIs, you can map fields and set up simple automations quickly. For more complex logic, you can combine multiple steps into a single Zap.

Use OAuth 2.0 tokens or API keys as configured. In most setups, you authorize Zapier to access the GHL Contacts API during connection creation. Rotate tokens periodically and store them securely in Zapier’s connection settings.

Common endpoints include GET /contacts/:contactId to fetch a contact, POST /contacts/ to create, PUT /contacts/:contactId to update, and POST /contacts/:contactId/tasks to manage tasks. These endpoints cover retrieval, creation, updating, and task management workflows.

Yes. You can chain actions such as creating a contact, then adding a note or a task associated with that contact, all within a single Zap. Use the endpoints for notes and tasks to enrich contact records and automate follow-ups.

No-code means you configure triggers, actions, and mappings using the Zapier UI. You don’t write code; you connect the GHL API to your apps through predefined blocks, then test and deploy. This speeds up setup and reduces maintenance overhead.

Rate limits depend on your GHL plan and API usage. If you approach limits, stagger requests, cache responses where appropriate, and consider batch operations where supported. Zapier will show errors when limits are hit so you can adjust the workflow.
