This functionality was removed in Update 23.
SmartPlant Foundation currently supports OAuth tokens issued by its built-in Security Token Service (STS), which is delivered as sub application of the Configuration Service called SmartPlant Foundation Authorization Server. SmartPlant Foundation can also support a token generated by the Smart API Manager (SAM) application, which is a fully featured application to manage the access to a variety of APIs from different applications.
The instructions for generating tokens using a REST client vary slightly between each different SmartPlant Foundation version. The process involves registering a OAuth client application with the SmartPlant Foundation Authorization service, and issuing a POST request to the token issuer application that contains the required information, such as user name, password, client secret, scope, and so on.
