Authenticate your requests to the Contacts API using OAuth 2.0 tokens, allowing secure access to contacts, tasks, notes, and related data through the Zapier App Connector.
Configure a secure connection in Zapier to store credentials and authorize calls to the Contacts API from your automations.

Automate data flow without writing code; set up triggers and actions in minutes.
Keep data synchronized across apps, reducing manual updates.
Scale workflows safely with built-in error handling and retries.
This section defines essential terms and the processes used to connect and automate data between Contacts API and Zapier App Connector.
An individual customer or lead stored in the Contacts API system.
A to-do item associated with a contact used to track follow-ups.
A free-form message or update attached to a contact.
Scheduled meetings or calls linked to a contact’s record.
Automatically create or update a Zap whenever a new contact is added.
Attach notes from the Contacts API into Zapier notes fields.
Create or update tasks in connected apps based on task activity in Contacts API.
In Zapier, choose Contacts API and authorize the connection using OAuth credentials.
Select triggers (new or updated contact, new tasks) and map actions to your workflows.
Run tests, review data sync, and activate the automation.
No coding is required; the Zapier App Connector provides a beginner-friendly interface to connect Contacts API with your workflows. Use prebuilt triggers and actions to automate data flow without writing code. Utilize Zapier’s built-in testing and error handling to ensure reliability and visibility into each step of your automation.
Common endpoints for syncing include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, GET /contacts/:contactId/tasks/:taskId, POST /contacts/, PUT /contacts/:contactId, and DELETE /contacts/:contactId. These cover core read/write operations for Contacts, Tasks, Notes, and basic contact management. Using these endpoints, you can fetch, update, and organize contact data across your connected apps within Zapier workflows.
Authentication is handled via OAuth 2.0 in the Contacts API, with credentials securely stored in Zapier App Connector. This ensures that all API calls are authorized and auditable. If needed, you can rotate tokens and manage scopes to limit access to only the required data (e.g., readonly for most syncs, or full access for write operations).
Yes. You can update contacts using PUT /contacts/:contactId and delete contacts using DELETE /contacts/:contactId from Zapier. For updates, ensure you map only the fields you intend to modify and validate responses in Zapier to confirm successful operations.
Errors trigger retries according to Zapier’s retry logic and the API’s rate limits. You can configure backoff strategies and monitor error responses to identify patterns. Zapier also surfaces detailed logs for troubleshooting and ensures failed tasks don’t break your entire workflow.
There are typical rate limits on the Contacts API; Zapier will retry with exponential backoff when you hit them. To optimize, stagger requests, batch operations when supported, and leverage webhooks or event-based triggers to reduce poll frequency while maintaining fresh data.
You can view runtime logs and task history within Zapier’s task history for each connection. Additionally, API responses and error details are accessible in your Zapier task details to assist with debugging and monitoring.
Due to high volume, we will be upgrading our server soon!
