Refactoring Web Services

Hi everyone! I have a web service with multiple methods and I just want to ask if it is better to combine all the methods into one and put a parameter('action') to determine what controller to run.

What do you think is faster, maintainable and easy to extend?

Thank you!

There is no silver bullet and it heavily depends on details.

I personally would go with several endpoints to have all the handlers clean and relatively tiny.

I would suggest to seperate them from start, it will help you in future as code base starts to grow. Try to think of SOLID Principles ( when coding.

In my opinion, it is better to separate each methods according to its usage. It would be maintainable in the long run.

In addition Eldlabs' suggestion, don't forget 12 Factor App while writing web services.
