To access the Contacts API through Zapier, obtain an OAuth token or API key from your GHL developer settings and securely enter it in the Zapier App Connector. This ensures requests are authenticated and scoped to your contacts.
In Zapier, connect the Zapier App Connector to GHL by selecting the Contacts API, choosing OAuth or API key flow, and granting required permissions. Test the connection to confirm access.

Automate complex workflows without writing code.
Seamlessly sync data across apps (CRM, tasks, notes) in minutes.
Improve data accuracy with real-time updates and validation.
Elements include endpoints (URLs), triggers, actions, authentication, data mapping, and error handling. Processes cover configuration, testing, and deployment.
A specific URL in an API that performs a defined function, such as retrieving a contact.
An event in the connected apps that starts an automation in Zapier.
An operation executed in response to a trigger, such as creating a record.
Methods to prove identity and authorize requests (OAuth, API keys, tokens).
Summarize new or updated contacts and send a daily digest to your team via email or Slack.
Push status changes to Google Sheets, Slack, or a project board.
Trigger onboarding sequences in Zapier when a new contact becomes a customer.
Generate credentials in GHL and connect Zapier App Connector using OAuth or API keys.
Select endpoints 1-17 and map fields between Contacts API and Zapier fields.
Run tests in Zapier, verify triggers and actions, fix issues, then enable automation.
Authentication is handled via OAuth or API keys. Start by obtaining credentials from your GHL developer settings and securely connect them in the Zapier App Connector. This ensures all requests to the Contacts API are authorized and scoped to your account. If you run into token expiration, refresh tokens or re-authenticate to maintain seamless access. In practice, using OAuth provides a smoother user experience with automatic token refresh, while API keys can be suitable for server-to-server integrations with tighter control over permissions. Always follow best practices for secret management and rotate credentials regularly.
The integration supports core endpoints for contacts, tasks, notes, and appointments, including retrieval and updates. You can pull contact records, task lists, and related notes or appointments to drive downstream automations in Zapier. Not all endpoints may be used in every workflow, but the connector exposes a thorough set to cover common use cases. Always map only the fields you need to minimize data transfer and ensure data privacy across apps.
A GHL developer account is required to obtain API credentials and configure access controls. With a developer account, you can generate OAuth clients or API keys, manage scopes (e.g., contacts.readonly), and monitor usage. If you don’t have one, request access from your GHL administrator or support. Once credentials are issued, you can connect them to the Zapier App Connector and begin building automations.
Yes. The integration supports data mapping between GHL Contacts fields and your Zapier fields. You can align fields such as email, name, phone, and custom fields to ensure data flows accurately between systems. When mapping, consider field types and validation rules to prevent data mismatches and errors in your workflows. If you update mappings, re-test triggers to confirm that changes propagate correctly.
Updates can be real-time or near real-time depending on the endpoint and configuration. Triggers fire when a relevant event occurs (e.g., contact update, new task). Some workflows may experience minor delays due to network or API rate limits. Designing idempotent actions helps prevent duplicate results when retries occur.
Yes. This is a no-code integration designed for users who want to automate without writing code. Use Zapier app connectors, predefined triggers, and actions to connect Contacts API to your other apps. For advanced scenarios, you can still modify mappings and configurations through the dashboard without touching code.
Documentation for the Contacts API and Zapier App Connector is available in the developer portal and on the integration page. You can find API reference, authentication guides, endpoint details, and example workflows. If you need more, contact support or consult the knowledge base for examples and best practices.
Due to high volume, we will be upgrading our server soon!
