There are three different frameworks that can be configured using the GLU menu builder.
Type 1. Acknowledge is ON, and respond back to separate URL
This design is used when the USSD gateway requires an ACK message to be returned when the request is received. The ACK is returned in response to the incoming request, and the final USSD response is sent back to a different endpoint.


Type 2. Acknowledge OFF and respond back to different endpoint
It is possible to specify the response endpoint as a different endpoint to the incoming request. This different endpoint can be defined by selecting the correct connector and defining the relevant path or context name (response back url).


Type 3. Acknowledge OFF and respond back to the same endpoint as incoming request
This is a straight request and response model. The response generated in the menu builder will be sent back to the same endpoint as the incoming request.
