Help

Hi,
I’m trying to authenticate via a a chrome extension. Using identity.launchWebAuthFlow i can correctly get a code but when i try to exchange this code for an access_token and a refresh_token, i get a 403 error.
The url is correctly put in the permissions, i use a fetch to POST to the token endpoint, the data is correctly form encoded.

Hey @Illidev, Welcome to the Auth0 Community!

What type of application have you configured on Auth0 Side? Regular Webapp or SPA?
If you can DM me your HAR file to have a look will be great!

Regards,
Sid
