## Discussion

Discussion The signedPayload is a string of three Base64URL-encoded components, separated by a period. The string contains a JWS representation of the notification response body, signed by the App Store according to the JSON Web Signature (JWS) IETF RFC 7515 specification. The three components of the string are a header, a payload, and a signature, in that order. To read the notification response body, Base64URL-decode the payload. Use a responseBodyV2DecodedPayload object to read the payload information. To read the header, Base64URL-decode it and use a JWSDecodedHeader object to access the information. Use the information in the decoded header to verify the signature.
