I need help with sending workflow information in header/body of calls to custom connector. I am trying to load a drop down list in one of the parameters of a logic app using values returned from an API call. The API end point requires basic workflow information such as the resource group and workflow name which are normally available in headers of http requests from logic app execution.
Normally when I use @{workflow().name} in logic app's json, it is substituted with the workflow name. In case of custom connector, the WDL syntax is passed as is without any transformation.
Here is a simplified swagger json with all relevant sections.
