Set the required scope to contacts.readonly and follow the recommended authentication method supported by the Contacts API to securely connect to the Zapier App Connector.
In Zapier, register your app, configure OAuth or API key, and grant the Contacts API the appropriate scope to enable triggers and actions.
Endpoints supported by Contacts API for this integration:\n- GET /contacts/:contactId\n- GET /contacts/:contactId/tasks\n- GET /contacts/:contactId/tasks/:taskId\n- GET /contacts/:contactId/notes\n- GET /contacts/:contactId/notes/:id\n- GET /contacts/:contactId/appointments\n- GET /contacts/\n- GET /contacts/business/:businessId\n- contacts.write\n- POST /contacts/\n- PUT /contacts/:contactId\n- DELETE /contacts/:contactId\n- POST /contacts/:contactId/tasks\n- PUT /contacts/:contactId/tasks/:taskId\n- PUT /contacts/:contactId/tasks/:taskId/completed\n- DELETE /contacts/:contactId/tasks/:taskId\n- POST /contacts/:contactId/tags
Trigger when a contact is retrieved or updated in the Contacts API.
Action: Map contact fields into Zapier task updates or CRM fields.
GET /contacts/:contactId
contactId, email, name
Trigger when a new task is created in the connected app.
Action: Create a new task in Contacts API for the given contact.
POST /contacts/:contactId/tasks
contactId, title, dueDate
Trigger when a tag is added in the app.
Action: Apply the specified tag to the contact via Contacts API.
POST /contacts/:contactId/tags
contactId, tags
No-code automation with drag-and-drop workflow builders to connect Contacts API to your apps.
Automatic data sync, triggers, and actions reduce manual data entry.
Centralized data mapping ensures consistency across tools.
Key elements and processes include endpoints, authentication, data mapping, triggers, actions, and error handling.
Application Programming Interface – a set of rules and protocols for building and integrating software applications.
A specific URL path that exposes a resource or operation in an API.
OAuth is a standard for access delegation that authorizes third-party apps to access a user’s data without sharing credentials.
A URL that receives real-time data updates from an external service when a defined event occurs.
Automatically create or update a contact in your CRM when a new lead is captured in a form.
When a task is added in your project tool, create a corresponding task in Contacts API and notify teammates.
Automatically tag contacts based on behavior to segment lists for campaigns.
Create a GHL app entry in Zapier and authorize with the Contacts API to obtain client credentials.
Select the Contacts API endpoints you want to use as triggers and map fields for actions.
Run test connections, check rate limits, and deploy to your live workflows.
Authentication typically uses OAuth with a defined scope, such as contacts.readonly, to limit access. Use secure credential storage and rotate keys regularly. When setting up in Zapier App Connector, ensure your app’s auth flow handles token refresh gracefully.\nPro-tip: test authentication in a controlled environment before going live to avoid unexpected failures.
Read-only access covers endpoints like GET /contacts/:contactId and related read endpoints. This keeps data safe while you build read-driven automations. It’s ideal for reporting, dashboards, and notifications that don’t require modifying the source data.\nIf you need write capabilities, request elevated scopes and ensure proper governance and auditing in your workspace.
Yes. Writing endpoints such as POST /contacts/, PUT /contacts/:contactId, POST /contacts/:contactId/tasks, and POST /contacts/:contactId/tags allow you to create and update data from Zapier. Be mindful of rate limits and validate inputs to avoid failed requests.\nAlways test in a sandbox before deploying to production workflows.
Field mapping is typically done in Zapier’s action setup. You can map contact fields (name, email, phone) to target app fields. Some endpoints support batch updates, which helps minimize API calls.\nIf a field isn’t available, consider creating a custom field in the target app to receive the data.
Common errors include authentication failures, missing required fields, and rate limit exceedances. Use exponential backoff, retry logic, and clear error messages in your app.\nEnable webhook-based notifications where possible to reduce unnecessary polling.
Yes. The no-code approach leverages Zapier App Connector’s triggers and actions, letting you connect Contacts API endpoints without writing code. Use templates, test each step, and gradually expand your workflow.\nFor complex logic, you can add conditional filters and multi-step paths within Zapier.
API documentation and full endpoint lists are available in your GHL developer portal and the Zapier app settings for the integrated connector. Always check the latest version for endpoint updates and rate limits.\nIf something is unclear, reach out to your developer community or support channels for guidance.
