In order to run the workflow WF_REST_EXAMPLE_OAUTH20, you must first register an application at https://apps.twitter.com. Once the registration is completed, you will receive a "Consumer Key" and a "Consumer Secret". Use these to set the Client ID and the Client Secret in the Authentication tab of the REST Client agent.
Before you use the Twitter REST API, read the Rate Limiting documentation. If your registered application exceeds the rate limit, it may be blacklisted.
