# Redeem Tokens

> Deduct tokens from a customer's balance when they redeem a reward

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

Call this when a customer spends tokens in your app. The amount is removed from their available balance and returned to your token's reserve, ready to be re-awarded to other customers.

<Info>
  Treat this as a transaction. If the response doesn't arrive, check the customer's [`/balance`](/api-reference/tokens/read/balance) before retrying. Re-running the call deducts twice.
