This does NOT start watching by itself and takes no e-mail address or other personal data: it returns a consentUrl on www.livinisto.sk that the user must open themselves, enter their own e-mail there and confirm by clicking the link LivinIsto e-mails them. Never ask the user for their e-mail in the conversation and never open the link for them. An unconfirmed draft is deleted after 24 hours. Matching properties are e-mailed to the user and can also be read with intent_list_matches using the returned intentCode — keep it in the conversation. hiddenLimitEur is optional: the most the user would pay (for a rental, per month), stored encrypted and never shown to sellers or returned by any tool; pass it only if the user said it.
