What you’ll need
You don't need to be a developer to set up this integration. Follow this simple guide to get started:
- A Mailbox Power account
- A Relevance AI account with access to your workspace
- Authorization (connect securely via OAuth—no manual credential storage)
Security & Reliability
The integration uses secure OAuth authentication, ensuring only authorized workflows access your Mailbox Power data. Relevance AI handles API operations through RocketNotes endpoints in the background—so you don't have to worry about authentication tokens, request formatting, or rate limits.
Built-in request validation and response handling ensure your workflows run smoothly, even with complex API interactions.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.

- Handle responses carefully: Monitor response status codes and body content for successful API calls.
- Manage headers efficiently: Set appropriate headers while remembering Authorization headers are auto-managed.
