Frequently Asked Questions

What is the Contacts API integration

The Contacts API integration lets you connect Moosend contact data to apps via Zapier without code. It exposes endpoints to fetch, create, update, and manage contacts and related data such as notes and tasks. This enables you to automate campaigns, lead follow-ups, and customer communications from a single workflow platform. By using the Zapier App Connector, you can orchestrate data flow across systems and keep contact information synchronized in real time.

Authentication is handled securely through OAuth or API keys. Your credentials are stored by Zapier and are never exposed to the automation tasks. Ensure the contacts.readonly scope is present for read operations and obtain write permissions where needed for updates and creation.

The available endpoints include retrieving contacts, listing and managing tasks and notes, and adding tags. You can also fetch appointments and business associations. A full endpoint list is provided in the Endpoints Reference section to help you select the right operations for your workflow.

Yes. You can create new contacts with POST /contacts/ and update existing ones with PUT /contacts/:contactId. The connector also supports updating tasks and notes associated with a contact. Use appropriate authentication and validate data before triggering actions.

Webhooks for real-time events can be implemented depending on your setup. If webhooks are not directly available, you can poll endpoints like GET /contacts/ to detect changes and trigger automations in Zapier.

To test your Zap, use the built in test feature in Zapier after selecting the trigger and actions. Verify that data maps correctly from Contacts API fields to your target app and review any error messages returned by the API calls.

API rate limits vary by Moosend plan. Check the API documentation in the Endpoints Reference and monitor response headers for rate limit usage. If you exceed limits, implement backoff and retry logic in your Zap.
