## Discussion

The `signedPayload` object is a JWS representation. To get the transaction and subscription renewal details from the notification payload, process the `signedPayload` as follows:

1. Parse `signedPayload` to identify the JWS header, payload, and signature representations.
2. Base64URL-decode the payload to get the [`responseBodyV2DecodedPayload`](/documentation/AppStoreServerNotifications/responseBodyV2DecodedPayload). The decoded payload contains details of the notification such as the notification type and  data.
3. The `data` object contains a `signedTransactionInfo` (<doc://com.apple.documentation/documentation/AppStoreServerAPI/JWSTransaction>) and based on the notification type, a `signedRenewalInfo` ([`JWSRenewalInfo`](/documentation/AppStoreServerNotifications/JWSRenewalInfo)). Parse and Base64URL-decode these signed JWS representations to get transaction and subscription renewal details.

Each of the signed JWS representations, `signedPayload`, `signedTransactionInfo`, and `signedRenewalInfo`, have a JWS signature that you can validate on your server. Use the algorithm specified in the header’s [`alg`](/documentation/AppStoreServerNotifications/alg) parameter to validate the signature. For more information about validating signatures, see the JSON Web Signature (JWS) [IETF RFC 7515](https://datatracker.ietf.org/doc/html/rfc7515) specification.
