Fuckers didn't even give my account access to the fucking soap action I was calling after 3 weeks of email chains and other back and forth.

First the credentials I was given "we're fully set up" and now this BS??

Fucking test your live and sandbox environments work BEFORE you let your clients start their integrations.

And if they have issues, try to emulate the e-2-e test and prove you can complete the transaction yourself BEFORE emailing back 🤦
