I wish that APIs were more standardized. The tricky thing is that each one is so different from every other. There are definitely things you can learn and then apply to other APIs but it’s almost never the case – at least for me – that you get to a place where you feel like an expert on APIs.
Even with the tutorial I made (and I’m a teacher and specifically tried to make it as broadly applicable as possible), it probably would barely have even helped you with this.
That being said, this forum is a great place to grow our knowledge and hey, maybe you’ll contribute a tutorial on this specific issue and people will benefit from that info.
