AWS Microgateway

Hello I would like to know the json format of all the types of sensors sent to aws iot core in the topic

gateway/::Gateway_ID::/sensortype/::Sensor_Type::/sensor/::Sensor_ID::confused:

I have searched your documentation but can’t find anything about the json format that sensors send via aws iot core

About the format of the json structure These values can be changed? or customized?
