## `FOUND` Found

### Meaning

The sending bank holds a transfer for this reference and returned its data, as of the time we asked.

### What to do

Compare the amount, receiver and time with your order, then decide yourself.

## `NOT_FOUND` Not found

### Meaning

The sending bank holds no transfer for this reference at the time we asked.

### What to do

Hold the order and ask the payer for the slip again, straight from their bank app.

## `DUPLICATE` Duplicate

### Meaning

Your account already looked up this transfer.

### What to do

Open the first lookup in duplicate_of and check which order it belongs to before accepting it again.

## `PENDING` Waiting for bank

### Meaning

The bank does not show this transfer yet; we ask again for you for up to 15 minutes.

### What to do

Wait for the webhook, or read this lookup again after Retry-After.

## `UNAVAILABLE` Unavailable

No definite answer from the banking system right now.

### What to do

Send again with the same Idempotency-Key after Retry-After.

No Thai bank transfer-slip QR in what was sent.

### What to do

Send a slip image with a clear QR, or the QR text from the slip.

The file is empty, broken, too large or not a supported image.

### What to do

Save the slip as a JPEG / PNG / WebP image and send again.

The QR content is not what the bank issued.

### What to do

Ask the payer for the original slip from their bank app.

Check this transfer with the bank directly (days per bank on /docs/banks).
