REST API - where to pass ID parameter? in URL or in header

Question

I wrote a small web service with REST API and after reading a few tutorials I cannot come to a conclusive answer.

If I wish to pass a user id to the REST API, should I pass it in the URL like so:

127.0.0.1:8080/users?userid=716360178

Or like so:

127.0.0.1:8080/users/716360178

If I were to use the second one, how will I be able to retrieve the user ID from the URL? I'm using nodejs + express.

Please advise.

Answer 1

The second option you mentioned is the best way. Or at least the most conforming to the REST design.

Answer 2

The second option. Similar to: http://localhost:8080/ProjectName/rest/users/716360178
