1. 如果您使用Office许可框架Office商店本身将生成密钥/令牌，此令牌将作为请求的URL的一部分传递到加载项。  Office许可框架还提供您的加载项
   可以使用的Web服务验证密钥/令牌。因此，如果您使用Office许可框架，则无需生成自己的密钥或密钥验证服务。有关整个验证流程的说明，请参阅以下文章：

Hi,

We have developed an Excel add-in and are going to sell it through Office Store. The setup and key generation packages are ready. We need some information such as listed below:

1- How office store will distribute license keys? Can we provide them a list of generated keys?

2- How much is the transaction fee or any service fee from Office Store?

Any help would be appreciated. 

1. If you make use of the Office Licensing Framework the Office store itself will generate the keys/tokens, this token will be passed onto the add-in as part of the requested url. The Office Licensing Framework also provides a web service which your add-in can use to verify the key/token against. As such you don't need to generate your own keys or key verification service if you use the Office Licensing Framework. See the following article for an explanation of the entire verification flow: here.
2. Microsoft charges a 20% revenue share charge for all paid add-ins.

Hope this helps.
