#### Overview {#overview}

**Actors:** Issuer developer, Mastercard Global Benefits Platform  

**Preconditions:** Card has an active segment assigned; the requested expiry date is on or after the segment's effective date  

**Outcome:** The segment and all its associated bundles are expired on the specified expiry date; no new segment is assigned  

**Endpoint:** `PUT /card-segments-cancellations` --- use this endpoint to permanently remove a segment from a card; use [Freeze/Unfreeze](https://developer.mastercard.com/benefit-allocation-service-mtls/documentation/use-cases/card-operations/freeze_unfreeze/index.md) if you only need to temporarily suspend benefits

Cancels the segmented benefits associated to the card by taking card number, segment name and expiry date as the input.
The response is an array of bundles that are cancelled on the card for the given expiry date. Exactly one input segment is supported at this time.
