(DataFlex) X.com Verfiy Credentials (Deprecated OAuth 1.0a Authentication)

See more X Examples

Returns an HTTP 200 OK response code and a representation of the requesting user if authentication was successful; returns a 401 status code and an error message if not. Use this method to test if supplied user credentials are valid.

X.com historically used OAuth 1.0a for authenticating API requests. However, as of April 2023, Twitter has deprecated OAuth 1.0a and migrated to OAuth 2.0 for most of its API endpoints. This change was part of Twitter's effort to modernize its API and improve security.

That said, if you're working with a legacy system or have access to older documentation, you might still encounter references to OAuth 1.0a.

This example shows how Chilkat could be used with the older/deprecated Twitter v1.1 API calls.
