Is it possible to Integrate 2 applications with different OAuth2 grant-types?

Question

Im trying to link AWS Alexa with a backend application(SugarCRM 9.0) which handles OAuth2.0 but different grant-type (password and refresh) and AWS Alexa Requirements are authorization code grant type or implicit grant type.Is there a way to get around this?

I'm not sure if setting up a AWS manage active directory to integrate sugar's user with Alexa, because that will generate infrastructure to a solution that can probably be simplified.I used AWS SSO as an approach to link these service since AWS SSO enables you to makes it easy to centrally manage access to multiple business applications (but not between them)...

Answer 1

Probably not the answer you want.

You'll likely need to create a middleware service that has people do the Login with Amazon login, and a Sugar CRM login, so you can reference the unique customer ID Login with Amazon creates for them (which will be the same in your skill and middleware if you use the same app ID / security profile) with the access tokens you retrieve for them from SugarCRM.
