Does Auth0 support authentication and authorising in a distributed application?  
Front end running serverside React app for UI components on domain [a.com](http://a.com) and back end business logic on a node app running on domain [b.com](http://b.com). The node app needs to know the user credentials and role.  
If this is supported is there a tutorial/ documentation ?

Thanks

Hi @rationem,

Thanks for reaching out to the Auth0 Community!

I understand you would like to know if Auth0 Supports authentication and authorization.

Yes, we offer both authentication and authorization in the Auth0 Product. I recommend checking out our [Auth0 React SDK Quickstarts: Add Login to your React App](https://auth0.com/docs/quickstart/spa/react/interactive) which has an example application and a guide on adding authentication using our Auth0 React SDK.

I would also recommend reading the following resources regarding authorization:

- [Configure Core Authorization Features for Role-Based Access Control](https://auth0.com/docs/manage-users/access-control/configure-core-rbac)
- [How do I assign Permissions to users?](https://community.auth0.com/t/how-do-i-assign-permissions-to-users/72278#how-do-i-add-permissions-to-roles-4)

Please let me know if there’s anything else I can do to help.

Thanks,  
Rueben

Hi - I can see and have a working example of Auth0 working for React. My use case is with a React frontend and a node (NextJs) API with all the business logic. I cannot see how to have the API authentication working with the React one so the API rest call requires logged in user and their role . I believe this is ‘backend for frontend’ scenario. Is there an example of this use case?

Yes, our [Auth0 Node (Express) API SDK Quickstarts: Add authorization to an Express.js API application](https://auth0.com/docs/quickstart/backend/nodejs/interactive) is a great place to start.

If you have any additional questions, please feel free to reach out again.

Thanks,
