I have attempted to use several Whatsapp chat providers and none have been as easy to set up and have provided the instant support of this team. Use with confidence they are crushing the whatsapp game and are a third party Shopify provider I can say I trust. Be careful alot of reviews dont signify current quality of service.

"Efficient, Reliable & Seamlessly Integrated!" Using FAST – WhatsApp Chat has significantly improved the way I connect with customers. The integration was smooth, and the app is impressively lightweight without compromising functionality. Real-time communication is now just a click away, which has boosted both customer satisfaction and conversion rates. I especially appreciate the intuitive design and prompt support whenever needed. Highly recommended for any store owner looking to strengthen their customer engagement!

What else can you ask for? A simple yet intuitive app that lets you connect with your customers through WhatsApp. Customizable and programmable, suitable for small businesses. Our experience has been good, which includes testing. Edit: One of the features we love about it is page-specific deployment of a floating widget with a smooth entrance animation. We use it only on the Contact page, which looks niche.

I've just set up this app and think I got lucky because it was free (for now). It's simple yet exactly what I needed to help my customers reach out to my small business via WhatsApp. The staff helped me set up a couple of final steps and ran a test to see everything was working ok. Great customer support and I wish the company the best of luck!

The app is extremely useful and easy to integrate! I wanted the WhatsApp button to appear on my product pages, and Grace from the support team went above and beyond — not only guiding me but personally configuring the placement for me. Her support was quick, professional, and very helpful. Highly recommended for anyone wanting smooth WhatsApp integration!

Fast installation. I had a doubt and it was solved fast, well not, actually inmediate response. The whatsapp button looks nice, it has a fast response. Just as expected! Recommend 100% for a simple and fast working solution
