jti property

String? jti
getter/setter pair

Specifies the desired jti claim (Section 4.1.7 of RFC 7519) in the returned App Check token.

Limited-use App Check tokens with the same jti will be counted as the same token for the purposes of replay protection. The size of this field is limited to 250 bytes. If specified, its length must be at least 16 bytes. If this field is omitted or is empty, a randomly generated jti claim with length between 16 and 250 bytes (inclusive) will be used in the returned App Check token. Leaving this field empty is only recommended if your custom attestation provider itself is not vulnerable to replay attacks.

Optional.
