I have been using the service and so far everything works smoothly. I set up integration between VK and CRM (data transfer from lead forms to cards) and plan to add a few more connections. It supports many popular services, including CRM systems, telephony, social networks, messengers, and so on, so the possibilities for creativity are enormous. I'm on the cheapest plan and pay about 1,000 rubles a month. I tested the service for free for the first two weeks, and I was pleased with its stability and the absence of errors. All actions are performed automatically and without failures. The website has instructions for many integrations, but in reality, everything is quite simple; you can figure it out through trial and error.
