Hi,
I want to display an image from an external API call. Currently, I can achieve this on the interface using a button, but it is not ideal. The user wants to load this image from the API on interface/page load without the need to click on the button. Is it possible? Below is the current call I use for the button. thank you.
a!buttonArrayLayout( buttons: { a!buttonWidget( label: "View API Image", saveInto: rule!GI_APIExternal_itemImage( imageNumber: Local!ImageNumber, onSuccess: { a!save(local!FTNICallresult, fv!result), a!save( local!AppianInternalDocumentID, rule!LCP_GetNumberOutOfText(local!Callresult.body.imageData) ) }, onError: { a!save( local!CallErrorMessage, fv!error.message ) } ), size: "STANDARD", style: "NORMAL" ) }, align: "START" )

I haven't tried this, so I have no idea whether it would really work, but just for the sake of thoroughness, what would happen if you declare a local variable as the result of the API call?
it would give me this because inside this call use smartservice to convert base64 into image: Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error : An error occurred when creating local!CallWebAPI. a!save() and smart service functions cannot be used in a local variable unless "refreshAlways" is true for that local variable using the a!refreshVariable() function.

And if you try using a local variable set to RefreshAlways?
