# Set SessionStorage

Set SessionStorage writes a key and value into browser `sessionStorage`. Use it to seed tab-scoped state before the application reads it on the same page session.

## When to use it

* Preload checkout or wizard state that lives only for the current tab.
* Set known test data so the UI opens in a predictable state.
* Pair with [Check SessionStorage](/test-steps/check/check-sessionstorage.md) or [Store SessionStorage](/test-steps/data/store-sessionstorage.md) to confirm or reuse the value.
