I explored the product and realized that it has much more to offer than described here and even at the website. Beautiful landing page. UI and UX both are good. Explanation of the product is nice. Finally a product for e-commerce business through which you can directly navigate followers to "buy now" page. Codes for the post are autogenerated in incremental order (although users can generate customized codes also) so it will be so easy for regular followers to understand the process. Discount coupon codes can also be used as the code for the post, so users will happily enter them to grab the discount.
This is a workaround that frankly, I think won't actually work that well in practice. Users are not going to read the details of having to type some code into the page that loads, they are going to quickly bounce when they hit it and are confused. The UX is extremely complex. I think the product would need to add analytics to make this more transparent. So users could see how many people are bouncing from the page that loads, and not actually inputting a code to go to their destination.
I don't think that asking followers to remember to type something after clicking on your link in your bio is really going to work out. This is too complex to expect good conversion ratios, in my opinion.
