[Integrations and API](https://site.faslet.me/knowledge-base/integrations-and-api) # Our chat assistant gets \`This product is not currently supported for Faslet sizing at this store\` for clothing too (our feed's product links end in an addition such as \`#158=5676\`) ## The question - We are connecting our chat assistant to Faslet's API. With our shop ID, the answer for a product, a cardigan for example, is `This product is not currently supported for Faslet sizing at this store. Some product types such as belts, socks, and jewelry are often excluded.` ## Applies to - A shop whose products reach Faslet through a product feed, with a chat assistant (such as Sleak.chat) or another integration that asks Faslet for size advice by the product page's address; any shop platform ## Answer Here the message doesn't mean your type of product is excluded. Our API finds the product by the address of its product page, and compares that address with the product links in your product feed. Some feeds, for example from a Magento shop, add something to the end of each product link that tells your own site which size to select when the page opens, such as `#158=5676`. Until 29 Oct 2026 we then didn't recognise the page address, so we didn't find the product, even when the assistant sent the address with the addition. That was on our side, and we fixed it on 29 Oct 2026: nothing needs to change in your feed or in your chat assistant, and you can test again with the same settings. Not sure this is it? Send us the address of a product page you tested with, and we check it. For setting up the assistant itself, see [we want to connect Faslet to our Sleak chat assistant](https://site.faslet.me/knowledge-base/connect-sleak-chat). ## Why it happens - Until 29 Oct 2026 Faslet stored each product's link from the feed as it was, addition included. The lookup removes such an addition from the address it is sent, but not from the stored link, so the two never matched. Since then the feed import normalises the stored links, unless that is switched off for the store. ## Is this your situation? - The product links in the shop's feed end in `#` or `?` followed by something, such as `#158=5676`, and the message comes back also for products that have Faslet's size advice on the shop's own product pages. - [Size advice](https://site.faslet.me/knowledge-base/size-advice) - [Products and size charts](https://site.faslet.me/knowledge-base/products-and-size-charts) - [Getting started](https://site.faslet.me/knowledge-base/getting-started) - [Fit Bar](https://site.faslet.me/knowledge-base/fit-bar) - [Look and placement](https://site.faslet.me/knowledge-base/look-and-placement) - [Returns and orders](https://site.faslet.me/knowledge-base/returns-and-orders) - [Integrations and API](https://site.faslet.me/knowledge-base/integrations-and-api) - [Portal, reports and A/B tests](https://site.faslet.me/knowledge-base/portal-reports-and-a-b-tests) - Solutions - [For Kids](https://site.faslet.me/en/products-kids) - About - [Blogs](https://site.faslet.me/blog) - [Press](https://www.deondernemer.nl/innovatie/startup-van-de-week-faslet-oplossing-online-maattabellen~3789309) - [Contact us](https://site.faslet.me/contact-us) - Partners - [Sign-up](https://portal.faslet.net/signup) [![Faslet | The Size and Fit Technology for online clothing stores](https://site.faslet.me/hs-fs/hubfs/Faslet-logo-rgb.png?width=640&height=264&name=Faslet-logo-rgb.png "Faslet | The Size and Fit Technology for online clothing stores")](http://faslet.me) [mailto:email@email.com](mailto:email@email.com) Copyright © 2026, Faslet B.V.
