New account linking issue on Android and Windows?

Hello,


We've had an Alexa Custom Skill in production for a couple of years now. Recently (that last 3 weeks or so), we've had a very fast ramp-up in Account Linking error reports - with no changes to the skill or related services.


The error is presented as an HTTP 400 from https://skills-store.amazon.com/api/skill/link/...


We are using an authorization code flow process, and have found in our logs that the redirect_url from our login back back to Amazon looks good (hasn't changed) - including both state and code parameters. We also see the code being exchanged for an access token within the required timeframe.


After some extensive testing, we've found that the error only happens to users on Android phones through the Alexa App, or on Windows. Users on iOS and OS X do not see the issue.


Is anyone aware of recent changes that might introduce a regression like this?

Hi @barry@amazon - the fix the Alexa team deployed seems to have helped significantly. We're seeing much better behavior against our prod skill. The dev instance was still acting a little oddly, but we're planning to run that through another series of tests to see if it was temporary.


Thanks SO MUCH for your help!

Hello @Brian Krygsman and thanks for reaching out.

There is no issue sharing your skill ID on the forum. Many developers do so. If it would make you fell more comfortable, you can open a case via our Contact Us page, where only the team supporting you would have access to it.

Regards,
Barry
