Now I'm doing Extending Appian Course of (Build an Application: Step 2 Use an Integration in an Interface) .
I want to call integration from interface with parameter.
In tutorial ,call integration with parameter of local variable.
I try to call integration with parameter i got error .like below...
[at function rule!ET_GetData [line 15]: Rule 'et_getdata' has 0 parameters, but instead passed 1 parameters.]

My Connected System Object is [HTTP] and
My Integration Object call to my http connected system object.

My question is how to configure my integration object when i call from interface with parameter?
