Add a Path Substitution Parameter to a REST Request

See more REST Examples

Demonstrates Rest.AddPathParam, which adds or replaces a path-substitution parameter. Before a request is sent, each occurrence of the name in the URI path is replaced with its value.

Background. Path parameters keep a URI path template readable—placeholders such as {userId} are substituted with concrete values just before the request is sent.
