Get Messages



The Get Messages activity uses the Slack conversations.list and conversations.history APIs to retrieve the most recent messages from a specified conversation (Conversation).

After retrieving the messages, the activity returns the properties in a Message[] object (Messages) that you can use as input property variables in subsequent activities (e.g., Message(0).Files in Download File, etc.).

How it works

The following steps and message sequence diagram is an example how the activity works from design time (i.e., the activity dependencies and input/output properties) to run time.

  1. Complete the Setup steps.
  2. Add the Slack Scope activity to your project.
  3. Add the Get Messages activity inside the Slack Scope activity.
  4. Enter values for the Input properties.
  5. Create and enter a Message[] variable for your Output property.
  6. Run the activity.
