# Is Expired

> Check whether a customer's tokens are past the inactivity threshold

<span style={{display:"none"}}>For the complete documentation index, see [llms.txt](/llms.txt).</span>

Returns `true` once the customer has been inactive longer than the expiry period configured on your token. Call this before [`/expire-tokens`](/api-reference/tokens/rewards/expire-tokens) to decide whether expiry should run.

Returns `false` if the token has no expiry configured, or if the customer has no recorded activity yet.
