New SafetyNet Attestation API deprecation field

[SafetyNet API Clients]

Hi there,

The SafetyNet Attestation API team is adding a new field to the SafetyNet Attestation API response. The new field contains information about the deprecation of the SafetyNet Attestation API to make developers aware that they need to migrate to the new Play Integrity API by June 30, 2023. See the deprecation timeline for more details.

What do I need to do?
Ensure that your integration with the SafetyNet Attestation API is compatible with the new field. Especially, make sure that this new field doesn’t break your parser or usage logic.

What is the new field?
The new field deprecationInformation contains information about the deprecation of the SafetyNet Attestation API and is added to the SafetyNet attestation response. The following excerpt shows the format and sample contents of the payload data.

{
    "timestampMs": 9860437986543,
    "nonce": "R2Rra24fVm5xa2Mg",
    "apkPackageName": "com.package.name.of.requesting.app",

    "ctsProfileMatch": true,
    "basicIntegrity": true,
    "evaluationType": "BASIC",
    "deprecationInformation": "..."
}

What is the timeline for the launch of this new field?
The new field will be gradually rolled out starting 2022-11-15. By the end of January 2023, the field will be in all attestation responses.
