Use Quick-Reply buttons in a Flow to offer the end-user a range of responses, to a question in a Gather module, in the form of buttons.
If you're gathering the user input into an entity or entity-assigned variable, make sure that the quick responses are valid values to avoid a button triggering a Fail Response.
The option to add responses manually is still available to the end-user.
Currently, these buttons are automatically rendered in the Test Experience window, but can also be used to pass key value pairs to a web channel in order to be used there, by bespoke buttons for instance.
Add Quick-Reply button
To add a Quick-Reply button to a Gather module in a flow -
Expand the Gather modules's Prompt section.
Open the Advanced Options menu and select Add Metadata
Enter in the Metadata section the following key value pair -
Text - quick_reply
Text/Entity/Variable - value will be both the button's label and the response returned on click
Repeat to create as many buttons as needed.
