Bounce management via API?

For bounce management, cronjob mautic:email:fetch is only for SMTP monitored folders.

How do you process bounces via API third-party services? such as Sendgrid?

Answering my own post.

After many different tests with SendGrid for bounce configuration - YES - mautic:email:fetch is only for STMP.

Had to have the exact email - example@test.com - in my mautic installation to test the webhook event in Sendgrid and confirm that it marks the bounce correctly.
