Hi @mstudioil,

Error message shows that you are using the incorrect Authorized JavaScript Origins or Authorized redirect URL. Please copy the URLs from wizard and paste as it is to the google console.

For reference, I have attached a document.

If the issue persists, you can create a ticket on our technical support channel.

It not letting me use site-name.com/folder-name

Hi @mstudioil,

I hope you are doing good.

The redirect URL of your site should be like https://xyz.com/wp-admin/options-general.php?page=postman.

It is a requirement of Google API, you can follow the Redirect URI validation rules for more details.

Thanks and Regards,
Support Team-WP Experts.
