Use OAuth 2.0 with scopes such as contacts.readonly to securely access contact data from the API.
Configure OAuth 2.0 in your Zapier app settings to authorize requests and manage token refresh for continuous automation.

Automate workflows without coding.
Build multi-step automations across apps.
Schedule regular data syncs and maintain data quality.
Core elements: endpoints, authentication, triggers, actions, and data mapping.
A specific API path used to perform an action or fetch data.
An authorization protocol that grants limited access securely.
Permissions boundary defining data access.
A URL that receives real-time notifications when events occur.
Create a new CRM lead when a contact is added in GHL via the API, then kick off downstream automations.
Automatically create and update tasks in response to events from support or sales apps.
Capture notes and tags in GHL and feed into dashboards for insights.
Set up OAuth 2.0 in both services and generate tokens.
Define data mappings for contacts, tasks, and notes.
Test triggers and actions, then promote to production.
With the Contacts API you can read contact data, fetch tasks, notes, and appointments. The API supports filtering and paging so you can pull exactly what you need. You can combine this data with Zapier to automate workflows without writing code.
Authentication is handled via OAuth 2.0. You will generate client credentials in both services and authorize the Zapier App Connector to access the Contacts API. Token refresh is automatic, so your automations stay connected.
Rate limits apply per token and endpoint. If you hit limits, you can implement retries with exponential backoff in Zapier and batch requests where supported.
Yes. You can create new contacts, update existing fields, and manage related data like tasks and notes through the API and Zapier actions.
Zapier can trigger on events such as new contacts or changes. Use webhooks or polling to sync updates in near real time.
No extensive coding is required. Use Zapier’s visual builder to configure triggers and actions. If you need advanced customization, you can insert a short code step or use Webhooks.
Logs and errors can be viewed in Zapier’s task history and the API’s response times. Use built-in debugging tools to diagnose issues.
Due to high volume, we will be upgrading our server soon!
