Invite to Channel


Uses the Slack conversations.invite API to invite Slack users (Users) to an existing channel (Channel) that you're a member of.

How it works

The following steps and message sequence diagram is an example of 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 Invite to Channel activity inside the Slack Scope activity.
  4. Enter values for the Input properties.
  5. Run the activity.

In the Body of the Activity

  • Channel Name - The channel that you want to invite the specified Users to. Enter a valid channel name String or use the drop-down list to select a channel from your workspace.
    • You must be a member of the channel to invite new members.
    • Before you can select a channel, the Slack Scope must be connected to the workspace. Connecting to the workspace is done by clicking the Connect button in the Slack Scope activity.
  • Users - A comma separated list of the Slack user names that you want to invite to the selected Channel. Enter a String or String variable.
    • Enter the user names using Slack's username syntax (e.g.,"Jean.Grey,Laura.Croft,Steve.Rogers,Peter.Quill").
    • The users must belong to the workspace that the Slack Scope is connected to. If the user already belongs to the channel, a already_in_channel error is thrown.
    • You cannot invite yourself to a channel (a cant_invite_self error is thrown). To join a channel, use the Join Channel activity.


  • DisplayName - The display name of the activity. This field supports only Strings or String variables.
  • Private - If selected, the values of variables and arguments are no longer logged at Verbose level.
  • ResponseStatus - The status of the request (success/failure information). Enter a ResponseStatus variable (UiPath.BAF.Models.ResponseStatus). The ResponseStatus object includes three properties that you can use in other activities.
    • Success - Boolean - Specifies whether the API request was successful.
    • ErrorCode - String - The response error if the API request is unsuccessful (Success=False).
    • Message - String - The error message.
