I am unable to create a new app with Yelp’s developer website. After several attempts to ‘Create App’ I have not received a single confirmation email from Yelp. So I am able to run the tutorial, but you tutorial videos are great nonetheless.

@joosty Thanks very much for your question!

What precisely is your problem? Are you selecting “Yelp Fusion” after going into the “Developers” section?

Hmm, make sure you’re going to [this link directly](https://www.yelp.com/developers/v3/manage_app).

Also, make sure that you check all required checkboxes and do the bot verification mini-game (“I’m not a bot…!” check).

I just tried on Google Chrome browser, and it worked for me. You can try using Chrome or another browser (sometimes, Yelp has issues with certain browsers, sadly), but it looks like this API is still supported. 🙂
