# Sec-Redemption-Record header



The HTTP **`Sec-Redemption-Record`** [Fetch Metadata Request Header](https://developer.mozilla.org/en-US/docs/Glossary/Fetch%20Metadata%20Request%20Header) is used by the [Private State Token API](https://developer.mozilla.org/en-US/docs/Web/API/Private_State_Token_API) when [forwarding redemption records](https://developer.mozilla.org/en-US/docs/Web/API/Private_State_Token_API/Using#redemption_record_usage_2). The header contains a list of issuer and redemption record pairs corresponding to each redemption record.

Note that a developer wouldn't be expected to generate `Sec-Redemption-Record` request headers — these are created automatically by the browser when invoking private state token `send-redemption-record` fetch requests.
