Please see https://docs.loraserver.io/lora-app-server/integrate/data/ for accessing the decrypted application payloads.

When you want to decode & decrypt a LoRaWAN PHYPayload yourself, please see: https://godoc.org/github.com/brocaar/lorawan#example-PHYPayload--Decode

For just decrypting the FRMPayload, please see: https://godoc.org/github.com/brocaar/lorawan#EncryptFRMPayload

Actually we have our application in java. We are not familiar with Go.
