  • Hi,

    I am trying the same but in my case the Apex method don't have any parameter explicitly defined. It is taking the Parameters from its API Query Parameters. Like this:
    > String vParameter = RestContext.request.params.get('Parameter');
    Will Your configuration remains same in this scenario as well?
    I am asking this because I implemened the configuration in exact same way How this blog defines, but here I am getting an error. Here:
    Error Statement: Missing Value at 26 [character 27 line 1]
    Error Type: Salesforce:Invalid_Response

    It looks like some how this error is linked with the "Apex Class Method Name" field in the Invoke Apex Rest Method component, but I am not getting what it is.
    Can you provide some tip for this?

    Thanks and Regards,
    Rahul Trivedi

  • Hi,

    The Apex Class Method Name is OK?? I am getting an error: "Invalid field value: ^/MuleSoft^HttpPost^String"
    The name proposed by Studio is: "callEmail (callEmail^/MuleSoft/*^HttpPost^String^msgbody=String, subject=String)"
