I have a NextJs application using the @auth0/nextjs-auth0 library. I am trying to store some metadata within user’s profile ( e.g. app\_metadata : { id: 123} ) with an axios call. How can I get the management\_api\_key?

I have manually put some metadata using the dashboard → User Management → Users → Metadata. And I have set a AUTH0\_SCOPE=‘openid email profile read:current\_user’ in my .env.local within my NextJs project. However when i console log the “user” using the useUser hook, I cannot see the user\_metadata.

So how can I create and read user metadata in my NextJs application? Thank you \<3

Hi @fnl,

Welcome to the Auth0 Community!

There are a couple of options when getting an Access Token for the Management API.

1. You could request an Access Token for the Management API by using a Machine-to-Machine application to perform a **Client Credentials** grant flow.

or

1. Using the [Auth0 Node.js Library](https://www.npmjs.com/package/auth0) to automatically get Access tokens for the Management API using the `ManagementClient` class.

Once you have obtained the token, you can call the Management API’s [Get a User endpoint](https://auth0.com/docs/api/management/v2#!/Users/get_users_by_id) to read the user’s app\_metadata.

Please see our [Get Management API Access Tokens for Production](https://auth0.com/docs/secure/tokens/access-tokens/get-management-api-access-tokens-for-production) documentation on getting an Access Token for the Management API.

Hoped this helps!

Please let me know if you have any further questions.

Thank you.

I am sorry, I am still very new to this. Would you be able to give me some more instruction please? Which method, out of those two, do you recommend more? Also am I supposed to fetch the access token within my NextJs app under pages/api/auth, or I should be setting up a backend route and call that api from the front end?

I have also read a post ([Yes, you can update user metadata with Next.js + Auth0 — build it nice](https://write.as/build-it-nice/yes-you-can-update-user-metadata-with-next-js-auth0)) saying I should put the below code within the pages/api/auth/[…auth0].ts. The post mentioned for some reason the scope is not read, therefore the code snippet in below is required

```auto
export default handleAuth({
  async login(req, res) {
    try {
      await handleLogin(req, res, {
        authorizationParams: {
          audience: 'https://api.example.com/products',
          scope: 'openid profile email read:current_user_metadata'
        }
      });
    } catch (error: any) {
      res.status(error.status || 400).end(error.message);
    }
  },
});

```

instead of just

```auto
export default handleAuth();

```

Thank you for your help

Hi @fnl,

Thank you for your response.

I would suggest option 2, to use the Auth0 Node.js Library to automatically get Access tokens for the Management API.

> [@fnl](#):
>
> Also am I supposed to fetch the access token within my NextJs app under pages/api/auth, or I should be setting up a backend route and call that api from the front end?

The former. Using the Auth0 Node.js library, you can make requests to read and create app\_metadata without being concerned with getting a token. After instantiating the `ManagementClient` class, you will automatically have an access token that you can make requests with the Management API.

Lastly, please make sure your `audience` value matches the Management API identifier found on your Auth0 Dashboard. Generally in the format `https://YOUR_DOMAIN.REGION.auth0.com/api/v2/`.

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

Thank you.
