Output

Parameter	Description	Data Type

In API workflows, a single response object is returned as the output. Any required fields can be extracted directly from this object.
In RPA workflows, some output parameters may differ, but the necessary values can still be retrieved from the response object even if they are not explicitly exposed.

Note:

Send Button Response must be used along with the Button Clicked event in a workflow. We recommend replacing, deleting, or replying to the button message or sending a personal message to the authenticated user by using the Response URL output from the Button Clicked event.

In the Send Message to Channel, Send Message to User and Send Reply activities, Message fields are passed in key:value pairs, separated by ;. Each message field in the Button Clicked response (irrespective of key or value) will be sequentially assigned, i.e. if key1:value1; key2:value2; key3:value3 are passed in Message fields, key1 is assigned to field1, value1 is assigned to field2, key3, and so on.
