...This being said, I was somewhat surprised that a parcel delivery service would not also have a REST API so I simply searched for that and found this: https://api.dpd.ro/web-api.html. This is going to be a lot easier to implement than SOAP-based communication.

There is usually a WSDL file (this is in XML) that describes everything that is possible. Based on the number of calls in the REST API, I fear the WSDL will be somewhat intimidating so I hope the documentation has slimmed down samples for specific requests.

SOAP requests use XML namespaces. If you are not familiar with those, that adds a layer of complexity.

SOAP ( in-path : String )
Constructs a new SOAP request and reads the SOAP envelope from the specified XML file.

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
 xmlns:ns="http://dpd.com/common/service/types/LoginService/2.0">
 <soapenv:Header/>
 <soapenv:Body>
 <ns:getAuth>
 <delisId>sandboxdpd</delisId>
 <password>xMmshh1</password>
 <messageLanguage>de_DE</messageLanguage>
 </ns:getAuth>
 </soapenv:Body>
<soapenv:Envelope>

function jobArrived( s : Switch, job : Job )
{
	var response = SOAP( job.getPath() ).send("https://public-ws-stage.dpd.com/services/LoginService/V2_0/?wsdl");
}

SOAP ( in-path : String )
Constructs a new SOAP request and reads the SOAP envelope from the specified XML file.

var soapRequest = new SOAP(inPath);

SOAP.send( url, soapRequest, "Some action");

DPD Portugal still doesn't have a REST API, as far as I know, so we've been using SOAP as well.

We ended up using a script (still legacy) to build the XML file, according to the documentation, and then outputting the file to the flow and using the "HTTP request" flow element to handle the call to DPD's servers.
It's not the neatest way to handle it, since you'll be getting the response in an opaque dataset, but for our level of programming skills, it worked alright.

Maybe this could be a starting point for you.
Letting Switch handle the details of the request implementation at first and once you have it working, trying to build it yourself in the script.

This is all a high-level kind of advice… As freddyp mentioned, getting the full documentation and perhaps some sample files will be most helpful.
