Oracle Visual Builder Cloud Service allows defining external REST service connections. In this post, I will explain how to implement query logic against such service. The connection is defined for ADF BC REST service.
Wizard provides an option to add query parameters: both static and dynamic. I have set one static parameter only Data=true, to return data only from the service. Also, I have created multiple dynamic parameters, the one used in this use case — q parameter. This parameter accepts query expression to filter data. Later in VBCS action chain, I will assign a value to this parameter, and service will be re-executed to bring filtered data: https://goo.gl/c3NNjc
