### Third-party Networks Application services can provide access to third-party networks via bridging. This allows Matrix users to communicate with users on other communication platforms, with messages ferried back and forth by the application service. A single application service may bridge multiple third-party networks, and many individual locations within those networks. A single third-party network location may be bridged to multiple Matrix rooms. #### Third-party Lookups A client may wish to provide a rich interface for joining third-party locations and connecting with third-party users. Information necessary for such an interface is provided by third-party lookups. {{% http-api spec="client-server" api="third_party_lookup" %}}
