Getting MailJet set up

I'm trying to figure out what goes where as seen in the support article https://support.cpanel.net/hc/en-us/articles/360058452373-How-to-use-Mailjet-as-a-Smarthost

In the code there's 4 placeholders: LOGIN, USERNAME, PASSWORD and SRS_SECRET

At Mailjet I have First name, Last name, our login email address & password, as well as an API Key and a Secret Key.

Ok, so the SRS_SECRET maps pretty easily, so I wonder what to use for the other 3. I don't think there's a USERNAME - maybe that's where the API key goes?

Then perhaps LOGIN and PASSWORD are what I use to log in to the Mailjet site?

I've tried a couple ways and I'm pretty sure I don't have it right, but what's strange is system emails do not work but roundcube emails do. So I'm hoping for some specific guidance to get these fields right then do additional debugging if needed.

  Try to leave public name as LOGIN and use your API key as username and SECRET key as password.

  Ok, thanks, that's basically what I have. From what I've learned I gather that the LOGIN and SRS_SECRET things aren't placeholders but literals. Now to debug why they don't show up in MailJet logs. Local delivery works but no sends show up in MailJet logs. exim_mainlog seems to show they were queued properly and I don't know how to debug further.   :(
