Hi @Lars Hendriks
Thank you for pointing that out.
I made a correction that.
Hi,
I've been going through a bunch of these tutorials and for both facebook and linkedin, when you click the button you can see it try to redirect real quick, but then does nothing and leaves nothing in my console. I've even tried using the jsfiddle links and just replacing the oauth token on the OAuth.init method to mine and I get the same behavior. I'm assuming there's something not right with how I have oauth.io set up (white listed domains maybe?). Any help would be greatly appreciated. Thanks!
Hi, @amoses12
Thank you for your sharing.
Yes, Domain & URL whitelist on OAuth.io config is caused problem.
To fix this, please go to the OAuth.io main dashboard, add the domain name of the webpage where you will the social login button into ‘Domain & URL whitelist’.
I add this step at "2. Create OAuth.io Account" in this post.
Thank you.
thanks for this clear tutorial bu I have perhaps a "dumb" question to add to this...
how do you set the page submit validation and redirect to the thank you page?
Can you update this with OAuth 2.0 please?
