# Cancel pending downgrade for a subscription contract

Cancels a scheduled/pending downgrade for a specific subscription contract. This endpoint removes the pending downgrade so that the subscription will continue with its current plan.

Important Notes:
- The downgrade must be pending (not yet executed) to be cancelled
- Once cancelled, the subscription will remain on its current plan
- An activity log entry is created when a downgrade is cancelled

Use Cases:
- Allow customers to change their mind about a scheduled downgrade
- Cancel downgrades when customers upgrade or renew
- Administrative cancellation of pending plan changes
