I'm using Passport and Facebook Strategy for authentication. It works fine from within my website. Clicking the login button makes a get request to auth/facebook/ and I succesfully log in the user.
I have the same url in the app details:
However the App Center Visit Website button adds this to the query:
{ fb_source: 'appcenter',
fb_appcenter: '1',
code:xxxxx...., // this is what i want
}
And upon clicking i get this error:
"Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request"
What i don't get is that this works AT THE SAME time on my website. How do I handle this extra parameters and log in the user upon clicking on the visit website button?
I also posted another question. I've been dealing with this for a while now and can't get my head around it...
note:
As far as I know, it is required for app approval that the Visit Button authenticates the user upon clicking and doesn't prompt them with another login message.
