I'm doing interviews for companies that would involve API integrations. I've done a couple now where I was given some general API information (some intentionally unclear, some more clear) and I felt I didn't do well. Mainly I was nervous, and felt very pressured just to understand how the different parts of the APIs interact with each other and should be interacted with. This is despite doing this for work and myself not feeling as nervous doing more common coding tests which I don't do as much at work(thanks to doing examples on hackerrank, Leetcode helping me feel more comfortable).
So what are the resources I should leverage to practice API integrations? How should I go about practicing? Especially considering that I do need to perform in a certain way during interviews.
I would recommend Shopifys APIs. Theres a lot to them, they’re well documented, and you can build a developers store for free.
Adobe commerce is another one. You can get a dockerized store up and running pretty quickly, also free and their documentation includes some basic suggested workflows.
Edit: these are mostly for practicing consuming apis, not sure if thats what you were looking for.
