@валентин​ did you follow this instruction? https://www.intercom.com/help/en/articles/4418-list-trusted-domains-you-use-with-intercom/p>

yes, but this in not my question. I need then Product Tours will be anywhere in which 3rd level domains the number of which is constantly increasing

Do you mean, you want to set up one tour and use it on all subdomains? Not sure if that works.

Where exactly are you stuck?

Yes, why not? Now Im trying use this: All of our subdomains are the same in structure

@валентин​ That might work, you just have to make sure, that everything you point at in the tour has the same css selector across all subdomains, and you should probably add another filter rule, otherwise it will also be shown on your homepage and all subpages

Thank you I'll try

If it works out I'll let you know or come back

Hi @валентин​ , To launch product tours in subdomains, make sure that the Intercom code installed there.
