## Setup Guide

### Step 1: Connect in DOS.AI Dashboard

1. In the **DOS.AI Dashboard**, open **Integrations** $\rightarrow$ **FinOne / Vbill Merchant Suite**.
2. Click **Connect Merchant**.
3. Enter your:
   * **Merchant ID**
   * **Partner Secret Key**
   * **Bank Account / QR Preset**
4. Click **Verify & Connect**.

### Step 2: Bind to Your AI Agent

1. Open your Sales or E-Commerce agent $\rightarrow$ **Integrations**.
2. Enable **FinOne / Vbill**.
3. Select whether the agent can automatically generate payment QR codes (`autonomous`) when customers confirm an order.

## Example In-Chat Payment Flow

1. Customer agrees to purchase products totaling 450,000 VND.
2. Agent calls:

   ```json
   generate_payment_qr({
     "amount": 450000,
     "order_ref": "ORDER-9821",
     "description": "DH 9821"
   })
   ```
3. Agent sends back a formatted VietQR image card with bank transfer details.
4. Customer scans QR code via banking app (Vietcombank, MB, Techcombank, etc.).
5. FinOne webhook alerts DOSClaw, and the agent confirms payment receipt to the customer within seconds.

| ---------------------------- | --------------------------- | --------------------------------------------------------------------------------------- |
| "Invalid Merchant Signature" | Partner Secret Key mismatch | Ensure the secret key in DOS.AI matches the key in FinOne merchant portal.              |
| Payment confirmation delayed | Bank NAPAS delay            | Check FinOne transaction dashboard or allow up to 30 seconds for bank webhook callback. |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.dos.ai/dosclaw/plugins-and-connectors/finance/finone-vbill.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
