# API reference: wallet sessions

Request a wallet challenge, create a session and revoke it.

Read [Wallet authentication](/noiho/developers/api-consumers/wallet-authentication.md) before you use these endpoints. Sign the returned challenge with your wallet, outside the playground.

> **Warning: Session requests change authentication state**
>
> A session request consumes a challenge. Logout revokes the current session. Never use a backend partner token in this browser panel.
