Get messages

Overview

The Get Messages activity calls the Microsoft Graph ListChatMessages or ListChannelMessages API to retrieve all messages from a specified chat (ChatId) or channel (ChannelId) and team (TeamID).

After performing the search, the activity outputs the properties in a ChatMessage[] object (Message) that you can use as input variables in subsequent activities (for example, ChatMessage(0).Id in Get Message Replies, Reply To Message, and so on).

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 Microsoft Teams Scope activity to your project.
  3. Complete one of the following two options (A or B):

A. Add an activity or run an external process that outputs a Chat.Id value (e.g., Get Chats).

B. Add an activity or run an external process that outputs a Team.Id value (for example, Get Teams) AND an activity or external process that outputs a Channel.Id value (for example, Get Channels).

  1. Add the Get Messages activity inside the Microsoft Teams Scope activity.
  2. Enter values for the Channel OR Chat properties.
  3. Create and enter a ChatMessage[] variable for your Output property.
  4. Run the activity.

Properties

The values for the following properties are specified when adding this activity to your project in UiPath Studio.

  • The variable you create for this property can be used as an input variable in subsequent activities (e.g., ChatMessage(0).Id in Get Message Replies , Reply To Message , etc.).

    * When using this variable as an input property value, specify the item in the array that you want to use (e.g., myMessages(0) ).

  • The ChatMessage object includes multiple properties that you can use in other activities.The example image below shows some of the properties that you can return.
  • Note - some properties listed in the designer are not applicable to the ChatMessage object (e.g., ODatatType ). For a list of the applicable Team properties, visit the links above.

Example

The following image shows an example of the activity dependency relationship and input/output property values.
