Anybody with experience integrating Mulesoft with QAD QXtend?

My company currently has integrations working through the Boomi platform, but we were able to convince them to switch to Mulesoft.  However, after signing the contract, they spent about 10 months debating whether we should just stick with Boomi, use both (yuck), etc.  As the sole integration developer at the company, I am now trying to migrate, test, and deploy the integrations in Mulesoft.    Onto the problem:  Our ERP system is called QAD (no surprise if you've never heard of it).  They have a plugin called QXtend that uses SOAP to facilitate integrations, and it is supposed to be the easiest, best practice approach.  At the same time, they are intensely particular about structure/formatting of inputs/outputs, and I am very stuck trying to get things working while I have until May 31 to complete the project.    I can provide more details if anybody is confident they can help, but before wasting anybody's time, some context:  - These integrations all exist in Boomi, but Boomi is a partner with QAD, so copying the configuration doesn't seem to work.  - We have worked with technical resources on the Mulesoft side and the QAD side (including support and a third party consulting agency), and nobody has been able to fully understand what isn't working and/or why.  - QAD documentation exists, but it is sparse and rarely helpful (in my opinion).  - There is an alternative REST api that can be used for some of the integrations, but QAD REST APIs require manually handling pagination, and we have yet to get that working.    Bottom line, if anybody has experience integrating with this platform or know someone who has, I would be happy to provide as much detail as needed if they think they can help.    Thanks everyone, and this is my first post, so forgive me if I'm doing this incorrectly.
