Setup was quick enough but it needs a real phone number once during setup which is kind of a hassle. still better than using telegram which has no encryption for the bot backend so the devs can read everything you write
No one talking about security, but I cannot argue that Telegram has by far the most powerful bot platform. People do with it great stuff.
It is always preferable to use WhatsApp to contact a business than calling up.
And unlike Telegram, for a WhatsApp bot you need to apply with a bunch of paperwork. If you're an SMB, you got little chances of ever getting access. They'll tell you to go with their Technology Partners and make a chatbot with these other BigTech companies like Freshworks, etc.
I run my agent over Signal with this, the only difference with Telegram is you need to host this. Other than that, it's great.
