+:::tip
+Instagram display app required callback URL to be configured in your Facebook app and Facebook required you to use **https** even for localhost! In order to do that, you either need to [add an SSL to your localhost](https://www.freecodecamp.org/news/how-to-get-https-working-on-your-local-development-environment-in-5-minutes-7af615770eec/) or use a proxy such as [ngrock](https://ngrok.com/docs).
