To send URLs, you need to verify that you are the owner of the site for which you send data. To verify this, use a special key: you need to generate it and place a file with it on your site. Yandex checks the key in every API request. The contents of the file and its location should be known only to you and the search engine.

Note. If your site has subdomains, use a separate key for each subdomain.

You can generate the key manually. Some CMS may also support IndexNow.
