### Widget
{% tabs %}
{% tab title="Redeem rNFT" %}
Moves the exchange into the dispute period.
To integrate the Boson Redemption Widget, all a seller needs to do is:
1. Add the following `
```
2. The Seller then needs to create a button with the fragment identifier *id="boson-redeem"*. When clicked, the redeem modal will popup on the Seller's website.
```html
```
### Using the Boson Redemption Button
As a seller you can also chose to use the Boson branded "Redeem" Button on your website, if you would like to do this, all you need to do is :
1. Add the below 2 lines of code in HTML `` section:
```html
...
```
2. Add the below class name to the "boson-redeem" button:
```html
```
#### Redeeming a specific rNFT
The Boson Widget's default behaviour is to show a buyer all of their redeemable vouchers, the widget be configured to direct a buyer to a given rNFT for redemption, this enables different user flows. This the way that the Widget is used on [the Boson dApp](https://bosonapp.io/).
A Seller can specify which exchange is going to be redeemed by the widget, by:
1. add a *data-exchange-id* tag to the "boson-redeem" button, specifying the exchangeId of a given exchange:
```html
```
You can find an example HTML file which embeds the

### Solidity
{% tabs %}
{% tab title="Revoke rNFT" %}
Burns rNFT, returns the price to the buyer. The seller's deposit is given to the buyer.
```solidity
IBosonExchangeHandler bosonProtocol = IBosonExchangeHandler(_bosonProtocolAddress);
uint256 exchangeId = 1534;
bosonProtocol.revokeVoucher(exchangeId);
```
{% endtab %}
{% tab title="Cancel rNFT" %}
Burns rNFT, and returns the price back to the buyer, except for the buyer's cancellation fee, which is given to the seller.
```solidity
IBosonExchangeHandler bosonProtocol = IBosonExchangeHandler(_bosonProtocolAddress);
uint256 exchangeId = 1534;
bosonProtocol.cancelVoucher(exchangeId);
```
{% endtab %}
{% tab title="Redeem rNFT" %}
Moves the exchange into the dispute period.
```solidity
IBosonExchangeHandler bosonProtocol = IBosonExchangeHandler(_bosonProtocolAddress);
uint256 exchangeId = 1534;
bosonProtocol.redeemVoucher(exchangeId);
```
{% endtab %}
{% tab title="Expire rNFT" %}
After the period ends, and if no actions were taken, anyone can expire the rNFT. The outcome is equivalent to the buyer's "Cancel rNFT" action - burns rNFT, and returns the price back to the buyer, except for the buyer's cancellation fee, which is given to the seller.
```solidity
IBosonExchangeHandler bosonProtocol = IBosonExchangeHandler(_bosonProtocolAddress);
uint256 exchangeId = 1534;
bosonProtocol.expireVoucher(exchangeId);
```
{% endtab %}
{% endtabs %}
### External actions
