Frequently Asked Questions
General Questions
Q: The button doesn't show
The button not showing normally means that, for the store, brand, and product ID sent to Faslet, a product has not been associated yet. By default, the button will not load unless it is connected to a product in the Faslet system. If you have any doubts, please reach out to support@faslet.me.
Q: I don't want the button to load on this product
No problem! There's no need to do anything on your side, except notify your Faslet representative of which products you'd like the button not to show on. By default, the button will not load unless it is connected to a product in the Faslet system. If you have any doubts, please reach out to support@faslet.me.
Q: There are new products on my store, where's the button?
When new products are added to your store, Faslet automatically detects this and our algorithms will get to work! There's no need to do anything from your side, and most new products will be live very soon after adding them. If you have any doubts, please reach out to support@faslet.me.
Q: What is a Faslet Tag and do I need one?
In short, no. Faslet used to group products by Tag, which was equivalent to a Size Chart Identifier, but this has since been replaced by using Product IDs. Tags are no longer required to use Faslet size-me and try-on.
Q: How can I access the partner portal?
If you would like access to the partner portal, your Faslet representative can activate your email address. Once that is done, you can simply click the button at the top right of this site, and log in with your email address.
Q: Does the size-me and try-on "categories" field allow multiple values?
Yes! Although we only use a single tag to identify the product, if you pass a comma-separated list of tags/categories to size-me and try-on, it will simply ignore everything else in the list.
Q: What data do you collect from users of size-me and try-on?
We collect only data necessary for size-me and try-on to function. That is the height, weight, age, and body profile of a user, that they have filled in themselves. Once they order, we also collect the order number and the product details. At no point do we intentionally collect any information that might personally identify a single user.
Q: We want to cache your code, can we?
Faslet size-me and try-on code is served from Amazon's Cloudfront CDN and is already gzipped, as such it should be very fast to load. Furthermore, we often update size-me and try-on, as such any cached scripts might be out of date, and unexpected behavior might occur. In short, please don't cache our code. If you have any performance concerns, please reach out to support@faslet.me.
Q: The button isn't showing, how can I see why?
In your browser, go to the product page where the button is not showing. Then open the developer tools. In Chrome, for example, this can be found in the menu under More Tools:

After opening the dev tools, reload the product page. You should see some text in the console that says Widget hidden: with analysis below. size-me and try-on will only show if the Shop, Brand, and ProdId are defined, Tag can be undefined. If these are all defined, and the widget is not showing, it could be a product that is disabled in the Faslet system, or is not yet active. If you have any doubts, please reach out to support@faslet.me.
Q: Do you provide code packages for our developers?
Yes! Right now we have a PHP Composer module for use in platforms such as Magento and Laravel. We are also working on an NPM package to simplify NodeJS and general frontend integration.
