# Create payment links

A payment link is the URL where the customer pays at VR Payment. The app creates it through the gateway API including invoice lines (`lineItems`).

#### Where you create links

| Document             | Action                                           |
| -------------------- | ------------------------------------------------ |
| Posted sales invoice | **Create payment link**                          |
| Sales order          | **Create payment link** (for example prepayment) |
| Sales quote          | **Create payment link** (for example a deposit)  |

The print rule must allow the document, otherwise you get a clear error.

#### Automatically on posting

If **Create payment link automatically** is on, the app creates a link when you post the sales invoice. If an active link already exists on the order or quote, it is **transferred** to the posted invoice (source type and document number are rewritten) – a second link is not created.

#### Status

| Status              | Meaning                                                           |
| ------------------- | ----------------------------------------------------------------- |
| **Active**          | Open link, QR code is shown.                                      |
| **Paid**            | At least one completed payment.                                   |
| **Expired**         | Valid-until passed (job queue or manual action).                  |
| **Cancelled**       | Cancelled manually or after an external settlement.               |
| **Paid externally** | Invoice settled outside VR Payment, link cancelled at VR Payment. |

Further actions on the document: **Update payment status**, **Cancel payment link**, **Show transactions**.

{% hint style="info" %}
`externalId` contains document number plus timestamp. After a cancellation you can create a new link for the same document.
{% endhint %}

{% hint style="info" %}
Address data is passed as URL parameters and pre-filled on the payment page. `billingAddressHandlingMode` is `NOT_REQUIRED` so a missing street does not block payment. The QR code uses the short base URL without address parameters.
{% endhint %}

## 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.solutioo.de/vr-payment-gateway/vr-payment-gateway_en_us/payments/payment-links.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.
