Message history lets you keep a history of changes to messages. These only include the changes to the following fields:

Text
Attachments
Any custom field

The value of the fields before the update, will be stored in the message history. Since the present state is already available and otherwise some information will be lost.

The time when the change was made (message_updated_at) and the user who made the change (message_updated_by_id) will also be stored.

This feature is only available on Stream’s Enterprise pricing plans. Request the Stream team to enable this feature for your app by contacting support.

Example

Confused about "Example"?

Let us know how we can improve our documentation:

Let's assume we have a channel with users alice and bob. We have the user admin with the admin role as well.

alice sends a message:

Note that sending a new message won't create a history record.

alice notices she didn't include her number. So she edits the message to include it:

This step will be recorded in the message history.

admin notices the message and since sending numbers is not allowed, he/she edits the message to remove the number:

This step will also be recorded in the message history.

Now customer support takes a look at message history by calling the server-side only API:

There will be two histories:

By default, you get the history sorted by latest first.
