Webhook for receiving transaction responses
Message correctly received. Does NOT mean the transaction was succesful. Further responses might be sent back on another message.
Invalid message (e.g: invalid signature)
Message ignored, because it was already seen and processed before by the receiver. Typically happens when a message is re-sent because the sender isn't sure if it was correctly received (e.g: network failure when the 2xx response was in flight)'
