Hi guys, I’m integrating my ERP to Apple GSX API, and I have some doubts.  My customer sent to my this link (https://eservicecentral.apple.com/), which I have a successful login. At this link, I can see swagger documentation, but I don’t have enough information about the first token. Googling I saw another link (gsxapi.apple.com) and it seems to be an old API using WSDL, not JSON/RESTFUL. What is the main URL from API (the newer one)? How do I authenticate to this API? Where do I get first token? Where I can find documentation about these steps? I saw a FAQ (https://gsxapi.apple.com/apidocs/prod/html/WSFaq.html), but it says to generate a CSR and use a WSDL API, which I believe is outdated, because “eservicecentral” uses an JSON API. Do I need to generate a CSR or not for this newer API (json)? I saw that you have 3 different environments (GSXIT, GSXUT and GSX). Does the newer API have the same sandbox/production environments also? How do I access them? What are the main URLs? Where I get the correct instruction to connect to “eservicecentral”? API DOCs don’t say much.   I need some help to do my first connection and to understand the processes I need to follow. Also, I received this “gsx2.apple.com” to see things at browser. Are there any other URL’s that I should be aware of?
