Connect securely using OAuth 2.0 to grant your app access to contact data without exposing credentials.
Configure your app with a client ID and client secret, request the appropriate scopes, and exchange tokens to authenticate with the Contacts API.
Endpoints include: GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/tasks/:taskId; GET /contacts/:contactId/notes; GET /contacts/:contactId/notes/:id; GET /contacts/:contactId/appointments; GET /contacts/; GET /contacts/business/:businessId; POST /contacts/; PUT /contacts/:contactId; DELETE /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/tags
Trigger: retrieve a contact and its related data (tasks, notes, appointments) to populate your UI or sync caches.
Actions: call GET /contacts/:contactId and related endpoints like /contacts/:contactId/tasks, /notes, /appointments.
GET /contacts/:contactId
Key fields: contactId, name, email, phone
Trigger: create a new contact with POST /contacts/ or update an existing one with PUT /contacts/:contactId.
Actions: create/update contact, attach tags, add notes.
POST /contacts/; PUT /contacts/:contactId
Key fields: contactId, name, email
Trigger: create, update, or complete tasks via POST/PUT/DELETE on /contacts/:contactId/tasks.
Actions: create task, update task, mark completed, delete task, fetch task list.
POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; DELETE /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed
Key fields: taskId, contactId, status, dueDate
Automate data flows without writing server code.
Keep CRM data in sync with your app in real time.
Launch faster with ready-to-use endpoints and clear data models.
Definitions of the main elements and processes used in this integration, including endpoints, authentication, and data workflows.
A specific URL path used to perform a particular action against the Contacts API, such as retrieving a contact or creating a task.
The process of proving identity and obtaining an access token to securely call API endpoints.
The industry-standard protocol for authorizing apps to access user data without sharing credentials.
A callback URL that the API can use to notify your app about events, such as changes to a contact or task.
Pull contact data via GET endpoints and enrich your app’s profiles in real time.
Automatically create follow-up tasks when contact data changes.
Use webhooks to receive instant updates on contacts and tasks.
Obtain OAuth credentials and grant permissions to access contact data.
Map API endpoints to your app’s data schema and test requests.
Switch to production, monitor activity, and set up alerts.
The Contacts API exposes read and write endpoints, allowing you to retrieve contacts, their tasks, notes, and appointments, as well as create and update records. You can build dashboards, sync CRM data, and trigger automations from changes in contact data. You can surface data in your app and drive workflows with both read and write capabilities.
No extensive coding is required if you use the Zapier App Connector and built-in actions. For advanced scenarios, you can leverage custom code or server-side integration to transform data and implement complex logic.
OAuth 2.0 is used to authorize your app. You will obtain a client ID and secret, direct the user to authorize access, and exchange the code for access tokens. The access token is used to call endpoints, with refresh tokens renewing access when needed.
The endpoints cover contacts, tasks, notes, and appointments, plus business-level listing. You will typically use GET for retrieval, POST to create, PUT to update, and DELETE to remove records. Documentation includes example requests and responses.
Yes. You can create and update contacts and related records. Use POST to create, PUT to update, and DELETE to remove records. Always test changes in a sandbox or staging environment before going live.
Rate limits vary by plan. Best practices include paging through results, batching requests, and implementing exponential backoff on 429 errors to ensure reliable retries.
Webhooks provide real-time notifications for events such as contact or task changes. Configure a webhook URL, verify signatures, and handle retries to maintain data freshness in your app.
Due to high volume, we will be upgrading our server soon!
