How to send all my pages?

Sending all your site's URLs is not the purpose of Indexnow.

The sitemap serves this function, and you can find our sitemap module at this URL: https://www.store-opart.fr/p/44-module-sitemap-prestashop.html

The purpose of the Indexnow technology is to send new URLs, modified URLs, or deleted URLs to robots via this technology to accelerate the search engines' processing of these changes.
