Use it in a flow

  1. Open a flow, open the node library and search for Mailgun.
  2. Drag it onto the canvas and choose an Operation and your connection.
  3. Map the operation's fields from earlier steps, or click Map with Matt.
  4. Use Test this step to see what it returns, then save.

To start a flow from Mailgun without a ready-made trigger: a Poll for changes trigger can check one of its list operations on a schedule and pass on only what is new; if Mailgun can send webhooks, a Webhook trigger receives them at its own URL.
