I've been trying to implement a soap request with a pem certificate and i'm just getting out of ideas. I know my code should be all wrong but i have no idea what the right direction is. I've been researching but found little no none documentation on this and the team behind the webservice i have to use also wasn't able to help.
I can already communicate with the service using SoapUI so i know the webservice works

Answer 1

Part of the issue is you're sending XML when you may not need to. PHP's built-in SOAP client will handle the XML for you, so you can focus on the objects (the O in SOAP!). You need to construct a data structure (object or array) and pass that to the operation you want to run. First look for the signature of the operation you want using:
$webService = new SoapClient($url, $configs);
var_dump($webService->__getFunctions());
This gives you the API - note that it indicates the data structures it expects in both the input parameters and the output. To see what those data structures look like:
var_dump($webService->__getTypes());
Now you can construct a PHP object with the same fields and structure and pass it in. Your code will look something along these lines:
$webService = new SoapClient($url, $configs);
$parameter = new stdClass();
$parameter->someField = 'N0003';
$parameter->anotherField = 'TESTE';
$result = $webService->requestFinancialOperation($parameter);
