The YumNiko team truly deserves praise. I have been using their services for six months, and my impressions are only positive. Working with WhatsApp and Telegram in both B24 and YumNiko, I noticed that we have good support in YumNiko, while B24 focuses on sales. I tried different messenger services and can say that each has its own features, which is quite normal for integration with external systems. YumNiko has many interesting functions: detailed descriptions of integration errors, the ability to forward messages between WhatsApp and Telegram, which other services lack. I haven't encountered any stability issues; the site was only unavailable for a few minutes a couple of times in the fall. There was one situation when one of the operators couldn't access the system, but it wasn't critical. As for the comments about WhatsApp, it's likely referring to the gray WhatsApp. All the services I used worked more or less fine, but for numbers with a high volume of inquiries, it's better to use the official WhatsApp.
