Frequently asked questions

What is the Contacts API and how does it integrate with ProWorkflow?

The Contacts API exposes endpoints to manage contacts, notes, tasks, and appointments, which can be synchronized with ProWorkflow. This integration uses Zapier to connect and automate data between the two apps without coding, ensuring data consistency and smoother workflows.

You typically authenticate via OAuth or API keys. Ensure the token or key has the correct scope (for example, contacts.readonly) and rotate credentials regularly to maintain security. Both sides should validate permissions before allowing access.

Common endpoints include retrieving a contact (GET /contacts/:contactId), listing a contact’s tasks (GET /contacts/:contactId/tasks), and creating notes (POST /contacts/:contactId/notes). Field mappings should align core identifiers like contactId, email, and taskId to keep data synchronized.

No coding is required when using Zapier App Connector. You can set up triggers, actions, and field mappings through a visual interface. Some advanced users may customize mappings or add validation, but it isn’t required to get started.

Yes. You can map fields such as contact name, email, and custom fields between ProWorkflow and the Contacts API. Zapier lets you adjust data types, default values, and transformation rules to fit your workflow.

If errors occur, Zapier provides retry logic and error handling workflows. You can configure retries, backoff strategies, and alert notifications to recover gracefully and maintain data integrity.

A typical setup enables triggers for new or updated contacts and tasks, followed by corresponding actions in the opposite app. Testing each step ensures data flows correctly before deploying to live automation.
