Get Credentials without specifying a UserPool

[altibanna]

Forgive me if this is obvious but, I can't see a way to use the getAwsCredentials method without specifying a CognitoUserPool. My application just uses an IdentityPool with OAuth configured with Auth0 - which is managing my users. How can i specify getting credentials without also specifying a user pool and just provide the access token and login domain ?

I haven't try to use it w/o UserPool. Please search through https://github.com/aws-amplify/amplify-js issues. JS package has a significantly bigger community, and if it is possible there, we can do it in the current package as well.

Also you can rise an issue here as well - https://github.com/aws-amplify/amplify-flutter

So this is how I do it with the React Native libs

import { fromCognitoIdentityPool } from "@aws-sdk/credential-provider-cognito-identity";
import { CognitoIdentityClient } from "@aws-sdk/client-cognito-identity";

const awsRegion = 'us-east-1';
const cognitoIdPoolID = "us-east-1:my-id-pool-id";

async function buildApolloClient(accessToken) {
    return await fromCognitoIdentityPool({
        client: new CognitoIdentityClient({ region: awsRegion }),
        identityPoolId: cognitoIdPoolID,
        logins: { ['mydomain.us.auth0.com']: accessToken }
    })()
        .then((creds) => {

The access token is from a successful Auth0 login earlier in the flow. No user pool required. Creds is then populated with the correct access and secret keys etc.

I see. JS libs imports fromCognitoIdentityPool from aws-sdk (https://github.com/aws/aws-sdk-js-v3/blob/main/packages/credential-provider-cognito-identity/src/fromCognitoIdentityPool.ts)

Unfortunately, we don't have the fromCognitoIdentityPool method in the package. You are welcome to contribute if you wish.
