Updating/Editing a Message Already Sent

This example demonstrates how we can use the Send Message and Update Message Snaps to send update messages to one or more recipients. To update a message that you have sent to another Slack user/Channel/private group, you need to use the timestamp of the original message. The same can be done for multiple messages, at once.

In this example, we use the Send Message Snap to send a message defined as normal text (string) to a user. You can try with sending to a Channel or private group.

Message in Slack

Notice that when the Message field is not defined as an expression, the new-line character \n is not rendered as expected. 

We connect a Mapper Snap to capture the timestamp of the message sent. Alternatively, you can feed the timestamp using any other upstream Snap.

Mapper Output

Now, to update the original message, connect an Update Message Snap to the Mapper and pass the updated Message text, Channel/User and Timestamp values to it. The Snap replaces the original message with this updated message and shows the following output.

Notice that we have defined the New Message field as an expression and that it contains the new-line character \n that renders the message with multiple lines, as expected.
