FingerPrint should be Fingerprint

[nic]

Fingerprint is a single word, so the best keyword is Fingerprint with the lower-case 'p'.

Eg.:

{
  "Base64Data": "VGVycmlio=",
  "FingerPrint": "D7362B4CC546DB11"
}

should be:

{
  "Base64Data": "VGVycmlio=",
  "Fingerprint": "D7362B4CC546DB11"
}

Or, better:

{
  "data": "VGVycmlio=",
  "fingerprint": "D7362B4CC546DB11"
}
