I just had a brief look at the Magento 2 WSDL file.
Until 1.9 I used the WSDL file as part of my development (Delphi win 32) to have access to the functions, arrays, objects etc... This was very helpful.
I already found the functions again... totally different names though, so I have to redevelop everything... which is time-consuming, but possible.
But what I haven't understood until now is the login credentials with the token system. In V1.9 I had an API-User and the corresponding password, which I could use to get my session ID: e.g. mage.login(myLoginParam)
I already found the extension settings in the Magento backend. But I really don't have a clue how to submit those consumer key, secrets... etc.. I am connecting to Magento using the HTTPRIO component from Delphi.
Can anyone enlighten me?
