How devs use Sandbox API
-
Integrate your app with Mailtrap SMTP and API
Copy the credentials or grab the ready code available in the inbox settings. Send the first email to Sandbox SMTP server.
-
Run a check in your CI
Use API to validate if an email was indeed sent. Check automatically any other details – headers, attachments, links, etc.
-
Expand your tests
Set up recurring checks and use API to access other Sandbox features – spam score, HTML check, bcc tracking, and more.
