    Hi @manjotsingh057,

     

    Do you want to call WCF service to execute a SQL Server stored procedure with HTTP action of Microsoft Flow?

     

    I think we could call WCF service to execute a SQL Server stored procedure with HTTP action. The HTTP action only support five Authentication type currently: None, Basic, Client Certificate, Active Directory OAuth, Raw.

     

    When you create a HTTP action to make a call to WCF service within one authentication type of above types, you may face with a authentication failure, you need to check if you have provide proper credentials for the http request.

     

    Best regards,

    Kris

    Hi Kris,

    @v-xida-msft

    I have created a Web API which is deployed on our development server.

    I am able to call it successfully in browser, using Javascript, fiddler or even PostMan app but when i am trying to call it using MS flow it says "internal server error".

     

    I tried to call it using HTTP action but it says invalid uri.

     

    URL I am trying to hit : https://server/api/ControllerName/id

     

    Anything i am missing or doing wrong here ?
