Implementing Auth0 using JWT Token only

Hi @lakshya,

Welcome to the Auth0 Community!

Have you made sure that the request looks something like the following:

curl --request POST \
  --url 'https://YOUR_DOMAIN/oauth/token' \
  --header 'content-type: application/x-www-form-urlencoded' \
  --data grant_type=authorization_code \
  --data 'client_id=YOUR_CLIENT_ID' \
  --data 'client_secret={yourClientSecret}' \
  --data 'code=yourAuthorizationCode}' \
  --data 'redirect_uri=https://YOUR_APP/callback'

Usually, a 404 error indicates that the domain URL cannot be found. Please check that the domain looks like https://TENANT.REGION.auth0.com, for example, https://exampletenant.us.auth0.com.

Please let me know how this goes for you.

Thanks,
Rueben
