Use OAuth 2.0 with your GHL developer credentials to authorize the Zapier App Connector to access Contacts API endpoints (readonly access is typical for read-focused workflows).
In the Zapier workflow editor, connect your GHL account and grant the Zapier App Connector the requested scopes. Store tokens securely and rotate credentials regularly.
GET /contacts/:contactId — Retrieve a single contact by ID; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task for a contact; GET /contacts/:contactId/notes — List notes for a contact; GET /contacts/:contactId/notes/:id — Retrieve a specific note; GET /contacts/:contactId/appointments — List appointments for a contact; GET /contacts/ — List all contacts; GET /contacts/business/:businessId — List or filter contacts by business; contacts.write — Scope for write access; POST /contacts/ — Create a new contact; PUT /contacts/:contactId — Update a contact; DELETE /contacts/:contactId — Delete a contact; POST /contacts/:contactId/tasks — Create a task for a contact; PUT /contacts/:contactId/tasks/:taskId — Update a task; PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task complete; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Tag a contact
Trigger: When a contact is requested by ID, retrieve the contact and related data for use in downstream steps.
Actions: Get contact’s tasks, notes, and appointments to build a complete profile.
GET /contacts/:contactId
contactId
Trigger: New batch of contacts for a businessId is available
Actions: Create or update multiple contacts; map businessId to contacts.
GET /contacts/business/:businessId
businessId
Trigger: Changes to a contact or its tasks detected in GHL
Actions: PUT /contacts/:contactId to update; PUT /contacts/:contactId/tasks/:taskId to update tasks; PUT /contacts/:contactId/tasks/:taskId/completed to complete
PUT /contacts/:contactId; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed
contactId, taskId
No-code automation: Build powerful workflows in Zapier without custom development.
Faster integration: Connect Miro Insights data to Contacts API in minutes.
Scalability: Easily extend workflows as you add more endpoints.
Key elements include API endpoints, authentication, data mapping, and error handling. Understanding these will help you design reliable automations.
Application Programming Interface — a set of rules that lets your apps talk to each other.
A specific URL path in an API that returns or accepts data.
The process of proving identity to access an API securely.
Connecting fields from one app to another so data flows correctly.
Set Zapier to pull new Miro insights notes and attach them to the relevant contact in Contacts API.
Schedule periodic syncs to add/update contacts based on Miro insights.
When a note or task is added in Miro Insights, create a corresponding task in Contacts API.
Register your GHL app, obtain client credentials, and configure OAuth scopes for contacts.readonly.
Link the GHL account in Zapier and authorize the Zapier App Connector to access Contacts API.
Run sample tests, verify data mappings (contactId, businessId, etc.), and enable automation.
The read-only scope allows your app to retrieve contact data and related resources without making changes. Ensure you request the minimal required scopes for your use case. Always follow least-privilege practices.
In Zapier, use the Test action to call endpoints, inspect responses, and confirm field mappings. Use sample data to validate. You can also enable test webhooks to verify real-time updates.
Yes. Use PUT, POST, and DELETE endpoints to modify contacts or tasks as allowed by your permissions. Ensure you have write scopes and proper validation, and handle errors gracefully.
GHL supports OAuth 2.0 or API key methods depending on your setup. In most guides, OAuth 2.0 is used to securely authorize a Zapier app.
Rate limits vary by endpoint and plan. If you hit limits, implement batching, backoff strategies, and retries in your Zapier templates.
Map fields by selecting corresponding sources in Zapier’s action steps. Use sample data to verify that contactId, businessId, notes, and tasks align with your schema.
The endpoints list is available in the API reference section. In this guide, we summarize key routes and how they connect to Miro Insights data.
Due to high volume, we will be upgrading our server soon!
