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.Chilkat Android™ Downloads
