SlackBridge

Synchronize conversations across your Slack and Rocket.Chat workspace using SlackBridge to mirror messages between channels or private groups in real time. When you send a message in Rocket.Chat, it appears in the corresponding Slack channel, and vice versa. To set this up, create a Slack app that bridges both applications to sync the messages.

Using SlackBridge

1. In your Slack workspace, create a  channel.

2. In the message box, type the /add command and select Add apps to this channel. Add the RocketChatBridge app to the channel.

3. Return to your Rocket.Chat workspace and navigate to the directory to search for the channel you created on Slack.

4. Join the channel and send a message. You should see the message appear in Slack. Respond to the message in Slack, and you will see the response in Rocket.Chat.

If the messages don’t sync between Slack and Rocket.Chat, restart your workspace.

SlackBridge recognizes the same user across Slack and Rocket.Chat if the usernames match. This allows for consistent identification of users between the two platforms. It also supports message reaction.
