Use a secure API key and OAuth 2.0 access tokens to authorize requests to Contacts API. Store credentials securely in your Zapier connection settings.
To connect create a new Zapier App Connector connection and authorize with your Contacts API credentials. OAuth scopes may be required.
Key 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 example: when a contact is created or updated in Contacts API start a Zap in the Zapier App Connector
Actions: create or update a contact fetch tasks and update notes
Base endpoints: GET /contacts/:contactId and related paths for tasks notes and appointments
Key fields: contactId and taskId for related records
Trigger: a new or updated task for a contact in Contacts API
Actions: create update or delete tasks mark as completed
Path: /contacts/:contactId/tasks
Key fields: contactId, taskId
Trigger: note creation or update on a contact
Actions: add notes attach tags to contacts
Path: /contacts/:contactId/notes and /contacts/:contactId/tags via POST
Key fields: contactId noteId and tagId as applicable

In Zapier select Zapier App Connector and authorize with the Contacts API credentials
Choose endpoints to trigger events and map fields to your destination apps
Run tests verify data flows and deploy your automation
The Contacts API lets you access and manage contact data such as names emails phone numbers and custom fields. Using the Zapier App Connector you can automate workflows by triggering on changes and performing actions without writing code.
No coding is required for basic connections, as the App Connector provides point-and-click triggers and actions. For advanced scenarios you can use custom fields and mappings to tailor data flow.
Common endpoints for syncing contacts include GET /contacts/:contactId, GET /contacts/:contactId/tasks, and POST /contacts/. This lets you pull update and create related records in one workflow.
Authentication uses OAuth 2.0 and API keys; you authorize connections in Zapier. Scopes such as contacts.readonly ensure appropriate access; keep credentials secure.
Yes. You can trigger on note creation, task updates, and contact changes. Webhooks will push events to your app for real-time updates.
The API enforces rate limits to protect service quality. If you exceed limits you may receive 429 responses and should implement retries.
Check official docs sample templates and community guides for best practices. Experiment with test connections and review mapping strategies.
Due to high volume, we will be upgrading our server soon!
