Mattermost ↔ Matrix Connector

Mattermost Matrix Connector is a bridge between Matrix and Mattermost.The main use case is to share channels/rooms and chats between Mattermost and Matrix compatible platforms.

The integration to Matrix is based on the Application Service API. It means that matrix part of the connector must support this standard API. We are using the Synapse Matrix server in development. More information about Synapse Matrix platform can be found at.

Main use cases

Details on functionality

• Federated public channels are created by an administrator in Mattermost.
• Private federated channels can be created by all users in Mattermost.
• Private/Public rooms can be created by all users in Matrix. Public rooms in this context require invitations from creator.
• Direct message chats can be created in both platforms.

Remote users (Puppet users)

The connector create remote users automatically when a users is posting a messaging in Federated channel/room or chat. We call the remote users for puppet users. They are real users in the platforms but can not be used as an ordinary users. You can not use a puppet user for interactive login in the user interface.
