# JWSRenewalInfo

Subscription renewal information, signed by the App Store, in JSON Web Signature (JWS) format.

```
string JWSRenewalInfo
```

## Discussion

The `JWSRenewalInfo` type is a string of three Base64 URL-encoded components, separated by a period, containing subscription renewal information signed by the App Store. The App Store signs the string according to the JSON Web Signature (JWS) [IETF RFC 7515](https://datatracker.ietf.org/doc/html/rfc7515) specification.

The three components in the string are a header, a payload, and a signature.

- To read the subscription renewal information, decode the payload. Use a [`JWSRenewalInfoDecodedPayload`](/documentation/AppStoreServerAPI/JWSRenewalInfoDecodedPayload) object to read the payload information.
- To read the header, decode it and use a [`JWSDecodedHeader`](/documentation/AppStoreServerAPI/JWSDecodedHeader) object to access the information. Use the information in the header to verify the signature.
