适用于Amazon API GAteway的OAuth

Question

I have my Rest API's configured in API Gateway. I want to implement OAuth on top of it so that the access to the url's are authenticated. I know that Lambda functions will be required here. Following are my questions:
1. Any good third party oauth providers that I can link with my project?

2. Scaling needs will be pretty high, possibly around 1M/second. Will these providers be scalable enough?

I would want to be doing everything programmatically. Like mostly these providers will require registration in order to acquire client id's and secrets. I want that also to happen programmatically as the no of users signing up will be dynamic.

Answer 1

1. i find Authlete good and also provide a guide for Amazon API Gateway
2. Yes, they can scale pretty well (check the pricing section) if you are willing to pay enough
