Frequently asked questions

What is the Contacts API and what can I do with it?

The Contacts API lets you read and manage contact data such as names, emails, notes, tasks, and appointments. It enables you to build automations that respond to contact updates and keep your CRM aligned. Two paragraphs provide practical setup steps and examples to get you started.

Authentication is configured in the Zapier App Connector by using OAuth or an API key, depending on the provider. Ensure the correct scopes are granted for read and write access to contacts, tasks, and notes. Follow the prompts in the connector to securely store credentials and test the connection.

Available endpoints include a range of read and write operations for contacts, tasks, notes, and appointments. Common paths include GET /contacts/:contactId, POST /contacts/, and PUT /contacts/:contactId/tasks/:taskId to manage tasks. Review the endpoint list to determine which ones fit your workflow.

Yes. You can create new contacts with POST /contacts/ and update existing ones with PUT /contacts/:contactId. You can also create tasks for a contact using PUT /contacts/:contactId/tasks/:taskId, enabling end-to-end automation from contact creation to task management.

Note and task data, along with appointments, can be synced across systems. Use endpoints like GET /contacts/:contactId/notes and GET /contacts/:contactId/tasks to keep information aligned in real time or on a schedule.

API rate limits vary by vendor and plan. Plan for retries and exponential backoff in your automations, and monitor usage from the connector dashboard to prevent throttling during peak times.

Test the connection by running a sample Zap: trigger a contact creation, verify that the contact and related tasks/notes are created or updated in the target system, and review logs for any errors. Use sandbox data when possible to avoid impacting live records.
