See if they support the language I use. Don't wanna spend time writing fetch wrappers over their API endpoint urls (If I have to use many endpoints in my project) unless alternatives are no good. Community wrappers always have some problems. Had so many issues with Zendesk API with third-party nodejs wrappers not working.
See how responsive they are fixing bugs/feature reqs if their git repo is available.
Oh, lol. Nasty fetch wrappers is right. smh
