Example response

{
  "success": true,

    "status": "cancelled"
  }
}

Common error

Status 409 
{
  "type": "https://api.pagou.ai/problems/conflict",
  "title": "Conflict",
  "status": 409,
  "detail": "The transfer cannot be cancelled in its current state."
}
Fix: show the cancel action only from states your operators can still stop safely. If the state is unclear, retrieve the transfer first.

​
Rules

  • Confirm current transfer state before showing a cancel button.
  • Reconcile after any uncertain cancellation attempt.
  • Update operator UI only after webhook delivery or successful GET confirmation.
