Webtask is just insanely useful. Welcome to the world of microservices/functions-as-a-service. That this exists is, in a word, insane. Bless them.
Ironically, authentication functions seem difficult to implement. Lack of docs geared toward noobs. But what a noob can do here is amazing. #shrug
If you use "no code" platforms (which are hard to extend with code), Webtask will soon become your best friend.
Pros:Amazingly easy to make an API endpoint to do... whatever. Inspired me to learn node.js. **Not a developer... but I play one on Webtask.**
Cons:Documentation a bit lacking. Doesn't have a huge community forum AFAICT. (This seems important to some.)
