A mid-tier messaging system receives a request to initiate a communication session via a first messaging channel that includes a first messaging interface of a first messaging application provided at a user device and a first message provider of a plurality of message providers. The mid-tier messaging system establishes a first session that is mapped to the communication session. The mid-tier messaging system establishes the communication, using the first session, between the first messaging interface and the first message provider. The mid-tier messaging system provides, through the first session, first message communications between the first message provider and the first messaging interface. The mid-tier messaging system seamlessly switches to a second message provider service when the first message provider service cannot service an intent of the first communication session.
