If you really distill it, I've been doing API Glue for about a quarter century.

I connect to a 3rd party API with shitty specs and inconsistent output that doesn't follow even their spec, swear a bit and adjust my estimates[0]. Do some business stuff with it and shove it to another API.

But I've done that now in ... six maybe seven different languages and a few different frameworks on top of that. And because both sides of the API tend to be a bit shit, there's a lot of experience in defensive coding and verification - as well as writing really polite but pointed Corporate Emails that boil down to "it's your shit that's broken, not ours, you fix it".

At this point I really don't care what language I have to use, as long as it isn't Java (which I've heard has come far in the last decade, but old traumas and all that =).

[0] best one yet is the Swedish "standard" for electricity consumption reports, pretty much every field is optional because they couldn't decide and wanted to please every company in on the project. Now write a parser for that please.
