Android only.
Used to assert application identity in place of a recaptcha token. At
least one of (ios_receipt
and ios_secret
), recaptcha_token
, or
safety_net_token
must be specified to verify the verification code is
being sent on behalf of a real app and not an emulator. A SafetyNet Token
can be generated via the
SafetyNet Android Attestation API,
with the Base64 encoding of the phone_number
field as the nonce.
