Learn how to securely authorize access to the Contacts API so your Zapier workflows can read and manage contact data.
Set up OAuth or API token in Zapier to authenticate requests to the Contacts API.

Automate workflows without writing code using visual editors and pre-built actions.
Sync data across platforms in real time to keep records current.
Scale complex automations as your business grows with easy maintenance.
A quick glossary of API terms and processes you’ll use when integrating GHL with Zapier.
Application Programming Interface: a concrete set of rules that allow software to communicate.
A live data delivery mechanism that notifies your app of events in real time.
OAuth is an open standard for access delegation, used to authorize Zapier without sharing passwords.
A specific URL on an API that performs an action or returns data.
Create a contact with POST /contacts/ and immediately generate a follow-up task via POST /contacts/:contactId/tasks to ensure nothing slips through the cracks.
After creating a contact, apply descriptive tags using POST /contacts/:contactId/tags to enable precise audience targeting.
Pull contact data with GET endpoints to determine follow-up timing, then create tasks with POST /contacts/:contactId/tasks.
Obtain client credentials and authorize Zapier App Connector to access the Contacts API securely.
Set up routes such as GET /contacts/:contactId and POST /contacts/ to fetch and manage data.
Create Zaps that trigger on contact events and perform actions via the API to automate workflows.
The Contacts API gives you access to core contact data, tasks, notes, and appointments. You can read and retrieve detailed information for each contact, including related tasks and notes, to power automation and reporting. The available endpoints enable reading and viewing structures so you can surface data in your automations. In practice, you’ll often pull a contact record (GET /contacts/:contactId) and then fetch associated tasks (GET /contacts/:contactId/tasks) and notes (GET /contacts/:contactId/notes) to drive downstream actions.
Authentication is typically done via OAuth or API tokens within Zapier. You’ll configure credentials in the Zapier App Connector to grant secure, token-based access to the Contacts API without sharing passwords. Once authenticated, Zapier can call endpoints on your behalf as part of your Zaps. Always rotate credentials periodically and follow least-privilege access using the defined scope (contacts.readonly) to limit permissions.
Due to high volume, we will be upgrading our server soon!
