Passing array in GET for a REST call

Question

I have a url to fetch appointments for a user like this:

/user/:userId/appointments

How should the url look like if I want to get appointme

Answer 1

Another way of doing that, which can make sense depending on your server architecture/framework of choice, is to repeat the same argument over and over again. Something like this:

/appointments?users=id1&users=id2

In this case I recommend using the parameter name in singular:

/appointments?user=id1&user=id2

This is supported natively by frameworks such as Jersey (for Java). Take a look on this question for more details.
