Frequently Asked Questions

Is there a rate limit for the Contacts API?

Rate limits do apply to the Contacts API and depend on your plan and token. If you hit limits, consider batching requests or caching results where appropriate. For high-volume needs, request elevated quotas from your GHL admin or partner manager.

Contacts expose standard fields such as name, email, phone, company, and lifecycle status. Depending on your account configuration, you may also access custom fields and related records like notes and tasks.

Yes. You can create and update tasks with POST /contacts/:contactId/tasks and modify them with PUT /contacts/:contactId/tasks/:taskId. You can also mark tasks complete with PUT /contacts/:contactId/tasks/:taskId/completed and assign tags with POST /contacts/:contactId/tags.

OAuth is supported by the Zapier App Connector workflow. You can also use API keys in some setups. Ensure the selected flow matches your security requirements and your team’s preferences.

Testing endpoints in a sandbox or using a test environment helps verify authentication and data mapping. Use sample contactIds and mock responses to validate your Zaps before going live.

Notes can be retrieved via GET /contacts/:contactId/notes. Creation is not shown in the endpoint list, so verify with your integration architect or consider extending the API with a notes create endpoint if needed.

Read scope allows viewing data; write scope enables creating and updating records. For most automation tasks, start with read-only to test, then request write access as needed.
