Use OAuth 2.0 to securely authorize your Zapier app to access Contacts data via the Contacts API.
Configure your Zapier App Connector credentials to securely connect to the Contacts API, using API keys or OAuth supported by the endpoint.
GET /contacts/:contactId — Retrieve a single contact; GET /contacts/:contactId/tasks — List tasks for a contact; GET /contacts/:contactId/tasks/:taskId — Get a specific task; GET /contacts/:contactId/notes — List notes for a contact; GET /contacts/:contactId/notes/:id — Get a specific note; GET /contacts/:contactId/appointments — List appointments for a contact; GET /contacts/ — List all contacts; GET /contacts/business/:businessId — List contacts for a specific business; contacts.write — Write scope for Contacts API; 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 as completed; DELETE /contacts/:contactId/tasks/:taskId — Delete a task; POST /contacts/:contactId/tags — Add tags to a contact.
Trigger: A contact is created or updated in Contacts API to start a Zap.
Actions: Create or update the contact in your target app, create related tasks, and attach notes.
Methods involved: GET /contacts/:contactId, POST /contacts/, PUT /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, GET /contacts/:contactId/notes, POST /contacts/:contactId/notes.
Key fields: contactId, taskId, noteId
Trigger: Periodic or on-demand sync of all contacts and business-related data.
Actions: Sync contact lists to downstream apps, pull business-specific endpoints, and update records in real time.
Methods involved: GET /contacts/, GET /contacts/business/:businessId
Key fields: businessId
Trigger: Task events (create, update, complete, delete) in Contacts API.
Actions: Create/update/complete/delete tasks and attach them to the appropriate contact.
Methods involved: POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId, POST /contacts/:contactId/tags
Key fields: contactId, taskId
Automate repetitive contact workflows without writing code.
Achieve real-time data sync across apps and teams.
Quickly test, deploy, and scale automations with templates and built-in tooling.
This glossary covers terms used in this guide, including API, endpoints, OAuth, triggers, and actions.
Application Programming Interface — a defined set of endpoints that allows apps to communicate and perform operations.
OAuth 2.0 is an authorization framework that lets apps access user data without sharing passwords.
A URL path in an API that performs a specific operation.
A callback URL that receives real-time notifications from an API.
Automate new contact creation, assign onboarding tasks, and schedule welcome calls.
Aggregate contact data, notes, tasks, and appointments into a unified view.
Trigger reminders and tasks based on contact activity and engagement.
In Zapier, add a new connection and authorize using OAuth for Contacts API.
Choose a trigger from Contacts API and map actions to your target app.
Run tests, monitor runs, and turn on the Zap for automatic operation.
The Contacts API exposes a range of endpoints for retrieving and manipulating contact data, tasks, notes, and appointments. You authenticate once and then can compose Zaps that trigger actions across connected apps.
Yes. You must authorize via OAuth 2.0 or API keys, depending on the endpoint permissions. This ensures that only trusted apps can access contact data. The initial connection prompts you to grant scoped access, after which you can securely manage and rotate credentials as needed.
A broad set of endpoints is provided, including retrieving contacts, managing tasks and notes, and handling appointments. You can choose the exact subset you need per automation, and you can mix GET, POST, PUT, and DELETE calls to suit your workflow.
Absolutely. You can create, update, and delete tasks and notes using the corresponding endpoints. Map fields from your trigger to the API fields, and you can automate task creation and note logging in real time.
Use Zapier’s built-in test feature to simulate triggers and actions. Check API responses, adjust field mappings, and monitor runs to ensure data integrity before deploying.
Scopes vary by endpoint but typically include read and write permissions for contacts, tasks, notes, and appointments. Ensure your app requests only the necessary scopes to maintain security and compliance.
Due to high volume, we will be upgrading our server soon!
