Transmission Quickstart

The canonical first-send guide is API Quickstart. This page exists as the migration target for the legacy transactional quickstart.

Follow this order:

  1. Create an API key with Send via API permission.
  2. Verify a sending domain.
  3. Export the key as MAILTARGET_API_KEY.
  4. Send the first request through API Quickstart.
  5. Add webhooks before sending production traffic.
