Hi Wilson,
Just to give an update, I used the auth URL in the format you mentioned:
<< <clientid>.auth.<aws-region>.amazonco… >>
but I still couldn't get it to work. I was able to sign in, was redirected to the callback URI with an auth code on browser but postman kept complaining invalid_client and was never able to fetch a token.
So I created a new app client with a client secret, used that to signin and get an auth code from the /login endpoint.
I then manually called the oauth2/token endpoint in a new tab via postman using this auth code and bunch of other attributes as mentioned in the below guide:
medium.com/vedity/aws-cognito-token-generation-fo…
and managed to generate the token. I was then able to use the token to call my spring boot API.
So instead of doing it in 1 step, I ended up doing 2 steps but I am mighty pleased that my API is secure with AWS cognito, all thanks to you.
I am now planning to try out your Spring boot API + AWS Fargate guide.
Thanks a lot mate! God bless you!
