Configure OAuth 1.0a Authentication for REST

See more REST Examples

Demonstrates Rest.SetAuthOAuth1, which associates an OAuth1 provider so Chilkat computes the OAuth 1.0/1.0a signature for each request. The second argument selects whether OAuth parameters are placed in the query string or the Authorization header.

-- Important: See this note about string length limitations for strings returned by sp_OAMethod calls.
