<div><span>Updated: Mar 3, 2026</span></div><div>You can send a link to your entire product catalog by assembling a wa.me link and including it in a standard [text message](/books/meta-whatsapp/page/sending-messages-developer-documentation). When sending a text message, you can use the optional `preview_url` set to `true` to have the message render a set of product catalog thumbnails of any URL in the message `body` string.</div><div>Note that if you [disable the catalog](/documentation/business-messaging/whatsapp/catalogs/set-commerce-settings#enable-disable-catalog), wa.me links and the **View Catalog** button in catalog link messages display an **Invalid catalog link** message when tapped.</div><div>To assemble a wa.me link, append your business phone number, including country code, to the end of the following string:</div><div>```
<span>https</span><span>:</span><span>//wa.me/c/</span>
```
