# receipt_delivery_changed

> Receipt delivery content changed (HTTP 409).

| Field | Value |
| - | - |
| Status | `409` |
| Problem `type` | `https://docs.paypathiq.com/problems/receipt_delivery_changed` |
| Retryable | Not retryable |

## When this happens

The allocations of the confirmed Payment no longer match the receipt content that the delivery reference was issued for. A reference identifies one exact receipt, so it is never reused for different content.

Nothing was attempted.

## What to do

Contact [help@paypathiq.com](mailto:help@paypathiq.com) with the `requestId`.
