If you are planning to set up payment on your website through the LAVA payment system, you might as well not even try. On all the sites I attempted to connect, LAVA strictly adhered to its requirements. As a result, all three projects were rejected. Technical support responds with standard texts like, "Unfortunately, the security service does not provide specific reasons for rejection, as this could violate the confidentiality of the moderation process...". It feels like the moderators of this service were chosen at random, as they couldn't approve any of the three projects that fully met all the requirements.
