Validating application dialog associated with a triggering event identification within user interaction data received via a group-based communication interface

An apparatus for validating an application dialog received from an application that is external to a group-based communication system, wherein the application requires validation, by the group-based communication system, to communicate with a client device via a group-based communication interface associated with the group-based communication system, the apparatus comprising:

• a processor;
• and
• at least one non-transitory computer-readable media storing instructions that, when executed by the processor, cause the apparatus to:
• receive user interaction data associated with the group-based communication interface from the client device;
• parse the user interaction data to identify a triggering event, wherein the triggering event is associated with the application;
• and
• based at least in part on the triggering event being identified among the user interaction data;
• transmit, to the application, a request for dialog validation data associated with the triggering event, wherein the request identifies the application dialog associated with the triggering event;
• receive the application dialog and the dialog validation data from the application;
• and
• based at least in part on a determination, using the dialog validation data and one or more external application validation parameters, that the application is validated for communication with the client device via the group-based communication interface, output the application dialog to the client device for display by the group-based communication interface.
