To use Resend with Leap, you'll need to add a Resend API key, which you can create in the Resend Dashboard. Do not share your API key with others or expose it in the browser or other client-side code.
Leap will prompt you to set a secret value on the Infrastructure page. Paste your key value and click Update secret.
