Delphi XE - Help With 3rd Party Rest API

I need to use an API provided by another software company and link it into my Delphi XE project. They tell me this is a standard Rest API and you can view documentation here: [login to view URL] The new authentication is based on a standard called OpenId Connect - which is itself based on OAUTH. Their developers have pointed me to a c# example online here: [login to view URL] Our OpenId configuration endpoint is here: [login to view URL] I need a simple delphi program with two buttons and a memo box. Button 1: Login and gain token Button 2: Show all branches (return results to memo box) No clever code or functions. Just the code needed against each button so I can easily follow it and then add it to my application. As simple as possible please! Would like it in Delphi XE as I do not have later versions (Old project) if possible! I will provide login details to winner. Only apply if you are happy with Delphi / Rest API and can read the C sample program to understand the authentication. As I see lots of automated responses I will only review bids that mention Quill in the response to prove you have read the project requirements. Should be a nice quick job for someone who knows what they are doing. Many thanks
