I am trying to learn how it is possible integrate all this APIs on this link GLS Rešitve | GLS Pošljipaket to my web store. Every time I get lost and I don’t want to destroy my site while. programming this. If it’s possible to help I would be really happy or if you could programme it for me it would even better.
A good place to start if you want to test third-party APIs might be the Give and Get example the team created. It has a template as well so you can test in that environment without worrying about your site’s functionality nor design.
