Can't get access token for client

[ph1]

I can’t get access token for my client in application
My request

const token: any = await axios.post(
        Endpoints.DOMAIN + Endpoints.GET_ACCESS_TOKEN,
        {
            grant_type: 'client_credentials',
            client_id: process.env.AUTH0_CLIENT_ID,
            client_secret: process.env.AUTH0_CLIENT_SECRET,
            audience: Endpoints.DOMAIN + Endpoints.V2,
        },
        {
            headers: {
                'content-type': 'application/json',
            }
        }
    )

Request in documentation

  url: 'https://domain/oauth/token',
  headers: { 'content-type': 'application/json' },
  body: '{"client_id":"client_id","client_secret":"client_secret","audience":"https://domain/api/v2/","grant_type":"client_credentials"}' };

Hi @ph1 ,

What’s the error response you get back from the /oauth/token endpoint?

Hi @supun,
Request:

data: {
      error: 'unauthorized_client',
      error_description: "Grant type 'client_credentials' not allowed for the client.",
      error_uri: 'https://auth0.com/docs/clients/client-grant-types'
    }

Hi @ph1 ,

Thank you for the response.

To use the client_credentials grant with your application, first you need to enable it for the application.

You can enable the client_credentials grant for your application by navigating to Applications → Select Your Application → Settings → Advanced Settings (bottom of the page) → Grant Types

Did you have a fix on this issue? Facing same issue but no response from anyone. mcdvoice

The problem was not solved, since I use a machine to machine connection, and this type is enabled there

Hi @ph1,

To further investigate, could you kindly DM me your tenant name and client id?

Thanks!

Hi @soubhagya ,

Welcome to the Auth0 Community!

I’m afraid, there’s no Dashboard UI setting available to pre-set the enabled grant types for newly created applications. However, if you use the Auth0 Management API to create applications, you can set the enabled grant types at the time of application creation.

Hope this helps!
