Flexify: Facebook Product Feed

What do I do when this warning shows up?
The HTTP server hosting the feed did not understand the request we made. This usually happens if the remote server doesn't support the chosen protocol or authentication method. Please ask your feed provider to check their server logs for more information and verify that your feed settings are correct.

An incredible app we've been using for almost 4 years now and fit our needs perfectly.

Thank you guys!

Good app, I can import all my product and creat dynamic adds. Very good support service. I Like this app

Great App. Helps keep things simple!

The most underrated Shopify app. Flexify is a life saver when Facebook gives you issues with your product catalog/pixel integration, which it does quite often. We've had this app installed for 5 years now.

This app works great and does exactly what it needs to do. Plus, their support team is amazing, very fast and super-helpful!

Great app, speacially for us, we carry several brands and 100´s of products, dozens of categories, this app help us to create upsells, cart recovery and many more due to the flexibiliity of how you can create ad sets with flexify.

One of the greatest support experience I ever had while working with Shopify apps. Very fast and helpful answers, with the best and very detailed documentation. Very recommended.

I've been very happy with Flexify, it is very intuitive and user-friendly. Great way to create a supplemental feed for our Facebook store, adding additional content that isn't provided by default through the Shopify/Facebook connection. Also, their customer support is TOP NOTCH - they helped me troubleshoot an issue with our Facebook product listings, and it turned out the problem wasn't even related to their app OR Shopify, it was caused by our Google Merchant Center app! But the Flexify rep identified the issue and provided me with a solution rather than simply referring me to Google. They deserve SIX stars just for that ;)

The best app around, for syncing your Facebook Product feed! Easy to use, no bugs and great support! I email Daniel because of a small error on Facebook's end and he replied in less than 24 hours with a solution!
