Shopthru

I was able to get things working and it looks like it was related to my custom theme. I had to install the Dawn theme, publish it, then go into the Shopthru app settings and make my campaign, then swap back to my custom theme, although the widget still does not exist in the list. I tried this on a different store with a basic theme and everything worked great. I'm sure once I can get the widget in, I'll be all set.

Previous review:

Wasn't able to get this working at all. After installing, I could not navigate to any of the app sections without an error. Tried hard refreshing, logging out, clearing cookies/local storage, and no luck.

I'd start by saying that the app itself is very good and works as advertised. Easy to use, good customization options and user-friendly for both merchants and website visitors.

What follows is however genuine constructive feedback:

despite all in all a positive experience, what I think is a HUGE let-down is that the floating botton, which is very very easy and convenient to set up, expands automatically every time a product page is loaded. I think this is really unnecessary and way too disruptive for website visitors considering that most of those actually interacting with the technology would be aware of it via other communication from the merchant. Both as a user and as a merchant I'd suggest a simple option for the button to only expand when clicked on rather than anytime a product is opened. The extra click contributes to consumer fatigue and may even be distracting.

I attempted to contact the team Shopthru team to see if they could simply stop this from happening (it would work great if it was just like the homepage where the button does not expand automatically) and they replied fairly quickly but did not solve the problem.

Nevertheless I recommend the app as it seems to be the best available option

Works really well, as stated by the developer - out of the box, with no code required. I would highly appreciate if there is an option to select a collection of products, not only single products, so that I don't need to constantly update the product selection when I do an exclusive product campaign.

This is the best of all the tokengating apps. I would know because I tried literally every one.

It has the slickest way of integrating the "Connect Wallet" button. Beyond that, and more importantly, it actually works! I couldn't get a single other tokengating app to actually recognize my tokens. And if that weren't enough, they have great customer service.

Five stars. Would recommend.

At this point I had to leave some kinda review and enthusiasm for this app. Despite being amazing the first day I tried it several months ago, it has undergone numerous updates and improvements. Moreover, the developer behind it is truly exceptional. Literally so good. They consistently make themselves available to assist with any queries or requests. The app itself has proven to be incredibly valuable in granting exclusive benefits to holders of my NFT, thanks to its wide range of token-gated features. Whether you have a small or large project and wish to provide benefits through Shopify, I strongly recommend giving this app a try.
