Overview

The ‘Slack Interactivity’ action integrates the Blink Bot for Slack into your workspace, allowing you to perform common Slack actions within your workflows. Messages from Blink to Slack are sent through the Blink bot
The ‘Blink Bot’ is named Blink by default and displays the Blink logo.
This action allows you to send a personalized message to a user or channel. The message can include a variety of interactive components, such as date pickers, checkboxes, text inputs, multiple choice selections, and more. Use this action to gather all the necessary information in a single interaction, formatted to best suit the type of data you are collecting. The Slack Interactivity action is made up of three distinct actions:
  1. The Send a Message action.
  2. The Update an Existing Message action.
  3. The Send an Ephemeral Message action.

​
Slack Interactivity Action

To use the Slack Interactivity action, it is essential to use the Slack Block Kit Builder for building and previewing your messages before executing the step.
The blocks passed to Slack Interactivity steps must include at least one actions block with a button element. Such button elements should have their value field set to a not empty, unique value.Input blocks must have their block ids set to a not empty, unique value.The only interactive element that is supported is a button element, and it should reside inside an actions block as described above. Including interactive button elements inside other blocks (e.g. accessory of a section block) will not block/fail the execution of the step, but will cause an error when the recipient presses the button.

​
The Slack Block Syntax

When using the Slack Block Kit Builder to create Blocks for the Slack Interactivity actions, it’s essential to remember that the Slack Block syntax differs from the syntax required in the Slack Interactivity blocks section.
