Disclosed systems and methods join a user to pre-existing primary communication channels based upon the information obtained from a user profile. Each channel hosts a different plurality of users and facilitates electronic communication between a corresponding enterprise data source and a remote user device associated with the user. The user is joined to one or more sub-channels associated within a primary channel. A message posted by the user is received and comprises a key identifying a sub-channel, an API token identifying the user, and a first communication. In response, an automated human interface module (bot), which includes a node graph to direct one or more states of a conversation, posts a responsive message including the key, the API token, and a second communication. The API token and key route the responsive message to the user device thereby initiating a secure conversation between the user device and an enterprise data source.
