I've been since friday with my boss trying to implement bridge between an SDK of another company for Android and iOS (yes the project is in React Native).
Today I've managed to put all the code that is needed to make that bridge and made tests. But in order to test the SDK functions, we need the info that should be easy to request through a service... The service is made with soap, using a certificate .p12.

*No problem, follow the documentation and everything will be okay* I thought... Even the example request in the docs doesn't give a 200 response. And when we finally made a 200 request, it still returned and error code...

And this isn't even the best part. Today we talked to the person that has been collaborating with us, and even he says "Implementing with this company is always hard". Even their worker knows it!!!!
