[Error] callback url

[tyf]

Hey there @JihooniiK welcome to the community!

Also, I have no idea how to set the callback URL in the “allowed callback URLs” section. And how to set the Config Vars in Heroku.

You’ll definitely need to add a callback url to the allow list first and foremost - You can find more info on that here.

Regarding Heroku in particular, there could many potential issues, but as in Auth0 you’ll need to set config/environment variables accordingly. I recommend checking out the following thread first for ideas:

Auth0 Integration With Heroku

Hi. I’m not sure if you still have the issue but what worked for me was adding missing env variables to Heroku. You can use the cli or go to applications → settings → reveal config variables and add your domain and client_id. Also thanks for the help Stephanie if you’re reading this.

Hope this helps!
