# Chase missing receipts

> Find card purchases that still need a receipt and attach one in a single call.

Cardholders forget receipts. This tutorial builds a small helper, such as a chat bot or a phone shortcut, that lists a person's purchases that still need one and attaches a photo to the right purchase. It works with any member's own API key, so each person only ever sees their own card.

## 1. List what needs a receipt

`attention.mine` lists purchases on the caller's own cards that still need a receipt, newest first.

```bash
curl -G https://app.getoatmilk.com/api/v1/accounting/attention.mine \
  -H "Authorization: Bearer $OATMILK_API_KEY" \
  --data-urlencode 'limit=10'
```

```json
{
  "data": {
    "total": 1,
    "cards": [
      "4242"
    ],
    "items": [
      {
        "id": "7f0f6c1e-1c1f-4b5e-9c8d-2f5e8e3c1a10",
        "merchant": "Synthetic Office Supply",
        "date": "2026-09-18",
        "currency": "CAD",
        "amountMinor": "4520",
        "lastFour": "4242"
      }
    ],
    "nextCursor": null
  }
}
```

## 2. Attach a photo to one purchase

Send the photo with `receiptFor` set to the purchase's ID. Oatmilk compares the receipt with that purchase only, and refuses it if the purchase no longer needs one.

```bash
curl https://app.getoatmilk.com/api/v1/accounting/uploads.inline \
  -H "Authorization: Bearer $OATMILK_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{
  "filename": "receipt.jpg",
  "mimeType": "image/jpeg",
  "contentBase64": "/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAA==",
  "receiptFor": "7f0f6c1e-1c1f-4b5e-9c8d-2f5e8e3c1a10"
}'
```

## 3. Or forward it by email

Some people would rather forward the email receipt. `inbox.address` gives the address to forward to; anything sent there from the person's own verified email is filed as theirs.

```bash
curl https://app.getoatmilk.com/api/v1/accounting/inbox.address \
  -H "Authorization: Bearer $OATMILK_API_KEY"
```

## Pause the reminders

While your helper does the chasing, a person can pause Oatmilk's own reminder emails for up to 90 days with `chase.preferences.update`.
