asterisk json

i would need to perform the following operation
-inbound call
-speech to text
-sending a json fle to an external service via restapi
-receiving the response, always in json
-readings of the variables in json
-continue dialplan

given the unfamiliarity, only what server to make a phone ring, it is necessary to receive documentation with the steps to configure the external services and the dialplan, it is possible to install any type of product
