Add a Query Parameter to a REST Request
See more REST Examples
Demonstrates Rest.AddQueryParam, which adds or replaces a query-string parameter. The 1st argument is the parameter name and the 2nd is its value; Chilkat URL-encodes both as needed.
Background. For a GET request the accumulated parameters are appended to the URL query string. For a form-url-encoded request the same parameters form the request body.
