How to get a Postmark API key

Checked by hand 2026-10-30

  1. Open Servers in Postmark and click the server your app will send from. New accounts already have one called My First Server.
  2. Click API Tokens. Postmark made a Server API token when the server was created, so it is already there; Footgun reads it from the page. Use Generate another token only if you want a separate one for this app.

What you end up with

  • POSTMARK_SERVER_TOKEN

Do it in one click with Footgun Keys
