Error: Login Required at requests to API

Help

Hi @maxhov,

Welcome to the Community!

When you call getAccessTokenSilently, the SDK will retrieve a cached token or perform silent authentication to retrieve a new Access Token. When you include the audience parameter, silent authentication will always take place.

The login_required error often occurs when the browser blocks third-party cookies during silent authentication.

There are a few ways around this:

  1. If you only need to interact with one API, then you can include an audience in your app’s AuthModule.forRoot settings and remove the audience from the getAccessTokenSilently call. You can also configure your app to use Refresh Token Rotation:
    AuthModule.forRoot({
      domain: env.auth.domain,
      clientId: env.auth.clientId,
      redirectUri: window.location.origin,
      audience: env.auth.audience,
      useRefreshTokens: true,
      cacheLocation: 'localstorage',
      scope: 'offline_access',
      httpInterceptor: {
        ...env.httpInterceptor,
      },
    }),
  1. If you need to interact with two APIs, and you control both APIs (the API that your app initiates within its AuthModule.forRoot settings and the one which you call getAccessTokenSilently for), then you may consider representing multiple APIs in a single logical API so that you only need to include the audience in the AuthModule.forRoot settings and not in the getAccessTokenSilently call:
  1. Use a Custom Domain so that the silent authentication will not be blocked: Custom Domains
