Customize Toast Message with Add-in Button

Dan Snyder

I am using the acknowledgement letter from an add-in button sample and I want to customize the toast message that displays to tell my colleagues where to find the created letter. I looked at the Invoke a web request guide and added sucessMessage to my application URL and I have the JSON entered from the sample in my Return response to Requestor step in my flow. However, with each I just get the default “The web requests action was successful”. Any help is greatly appreciated!

@Dan Snyder try adding Content-Type and application/json to the headers of the request.
