# 404 Not found

`https://api.quotastack.io/errors/not-found`

QuotaStack has nothing here with that ID. Nothing changed.

## Why it happened

- The ID is real, and it sits in the other environment. A sandbox key cannot see live data.
- The ID belongs to a different tenant.
- The record was deleted.
- You sent your own `external_id` where the call wants the QuotaStack UUID.

## How to fix it

1. Check that the key environment matches the data you want.
2. Use the `by-external-id` twin of the call when you hold your own ID.
3. List the collection first, to see what is really there.

### Example response 404

```json
{
  "type": "https://api.quotastack.io/errors/not-found",
  "title": "Not Found",
  "status": 404,
  "detail": "Customer not found."
}
```
