亚马逊 MWS 权限管理器 - 常见问题
我不小心撤销了一位开发者的权限，如何才能重新为他授予权限？
在管理您的应用页面上亚马逊 MWS 开发者对应的【操作】列下，点击【启用】按钮。
如果我无法通过开发者 ID 或开发者名称识别我的开发者，应该怎么办？
如需帮助确定亚马逊 MWS 开发者，请联系亚马逊 MWS 支持。识别出开发者后，您可点击开发者名称旁的【编辑】进行更改，以供日后参考使用。
撤销与暂停开发者对我的账户的访问权限之间有何区别？
如果访问权限被撤销，开发者将不能访问您的账户，同时所关联的 MWS 授权令牌将被销毁。如果您重新为该开发者授权，则需要为其授予新的 MWS 授权令牌，然后该开发者才能成功访问您的账户。
如果访问权限被暂停，开发者将不能访问您的账户，但 MWS 授权令牌会完整保留。如果您恢复该开发者的访问权限，该开发者能够立即访问您的账户，无需您授予新的 MWS 授权令牌。
启用两步验证是否会影响我的第三方连接？ （例如屏幕截取器、集成器，或数据聚合器。）
如果第三方使用屏幕读取技术通过用户名和密码登录您的卖家账户，那么两步验证可能会影响他们的一些连接。我们鼓励您探索卖家平台中的商城网络服务（亚马逊 MWS）或报告是否可提供您使用第三方所获得的功能。

Amazon MWS Permissions Manager - FAQ
I accidently revoked the permissions of a developer. How can I re-authorize their permissions?
On the Manage your apps page, under the Actions column for the Amazon MWS developer, click on the Enable button.
What if I cannot recognize my developers by Developer ID or Developer name?
For help identifying the Amazon MWS developer, contact Amazon MWS Support. After you have identified the developer, you can click Edit next to their Developer name to change it for future reference.
What is the difference between a developer’s access to my account being revoked and being suspended?
If the access is revoked, the developer will not be able to access your account, and the MWS Auth token representing the relationship is destroyed. If you grant access to the developer again, you will need to give them a new MWS Auth token before they can successfully access your account.
If the access is suspended, the developer will not be able to access your account, but the MWS Auth token will be left intact. If you restore the developer’s access, they will immediately have that access, and you will not have to give them a new MWS Auth token.
Will enabling Two-Step Verification affect my third-party connections? (Such as screen scrapers, integrators, or data aggregators.)
Two-step verification might affect some connections from third-parties using screen-scraping technology to sign in to your seller account using a user name and password. We encourage you to explore whether Marketplace Web Service (Amazon MWS) or Reports in Seller Central can provide the functionality for which you use a third-party.
