How do I pass a path variable to the rest URL?

Where does a parameter live in an endpoint?

This type of parameter lives within the endpoint’s URI – which looks like a web address – to help scope the call down to one individual resource. This is nice because it prevents you from having to build a body just to supply something as simple as a resource identifier. I’ll use an example endpoint from Rubrik to dive deeper.

Why do we use query and path parameters?

Resources that match both of these will be returned. And so forth. Much like the path parameter, the query parameter is nice because it’s just plopping data directly into the URI so that the endpoint knows what to do.

Where do the path and body parameters live?

The first one, Path, is something I briefly drilled through in the video. This type of parameter lives within the endpoint’s URI – which looks like a web address – to help scope the call down to one individual resource. This is nice because it prevents you from having to build a body just to supply something as simple as a resource identifier.

How are path and body parameters used in RESTful API?

You can even click the box to have all default values transferred over to the value area. With this endpoint, you’d supply both a path parameter – the {id} value of the virtual machine – and a body parameter – the JSON payload representing all of the values you wish to change for this particular virtual machine.
