VTL resolver to authenticate multiple users from two different cognito pools

Question

I need I have two cognito pools
One is for uber rider
One is for uber driver

now when I query from my rider side I need rider authentication from his pool on rides table and when I need to query from drivers side I need driver credentials for authentication from his pool to get data from rides table.

like this one
https://aws.amazon.com/blogs/mobile/graphql-security-appsync-amplify/

but with code gen amplify it self generate the VTL. but my problem is to write it by myself as I am not using amplify.

Answer

You can make all the changes to the GraphQL Schema or the template mapping of the resolvers in the AppSync Console, and you don't need to use Amplify for it.

Here is a [link to AppSync documentation](https://docs.aws.amazon.com/appsync/latest/devguide/security-authorization-use-cases.html) on the way to authorize different users to do different queries or mutations. It covers similar use cases to the one that you defined.
