Reference: Interaction payloads

Interaction payloads are sent to your app when an end-user interacts with one of a range of Slack app features.

The resulting payload can have different structures depending on the source. All those structures will have a type field that indicates the source of the interaction.

Read the individual reference guides to see the breakdown of each type of payload:

Payload type Description
block_actions Received when a user clicks a Block Kit interactive component.
message_actions Received when an app action in the message menu is used.
view_closed Received when a modal is cancelled.
view_submission Received when a modal is submitted.

Read our guide to handling payloads from user interactions to learn how your app should process and respond to these payloads.
