We are using LWA to authenticate for the Amazon Advertising API. Our users sometimes have Amazon 3P Seller accounts in multiple regions (usually one in North America and one in Europe) using the same Amazon credentials.
When they authenticate through LWA, we get a token that works for only one region.
The seller then has to log out of Amazon everywhere, then try to authenticate again, hoping that it works for the second region. We don’t have a repeatable, predictable way to get the user to authenticate in the separate region. Ideally, we’d love to specify the region programmatically so that users get a consistent, predictable experience to the intended region.
Advertising API Technical team says that it is not a limitation of the API, but a quirk with LWA.
I don’t see language or region covered anywhere in the LWA documentation. Any hints to making this work more correctly?
