The guide “Obtain AWS Tokens to securely call AWS APIs and resources” ( Integrate with Amazon Web Services and Products) describes the exact functionality that I want, but I created my Auth0 account after June 8, 2017. How do I achieve the functionality described in the guide with the API resources available to accounts created after June 8, 2017?
I’m afraid that this is something for which there is still no equivalent functionality on non-legacy flows so the restriction put in place in the date you mentioned removed the possibility to use that integration for new accounts. I’ll ask to put a warning on the linked docs page about this situation.
In addition, the lack of this functionality on the new flows is something that is being tracked and should be addressed in the future, however, at this time I can’t provide any definitive timeline.
