Oh, so is that working well? Years ago I tried a WhatsApp-XMPP-Bridge and it made Whatsapp lock my account due to policy violations or something like that.

@denkbeteiligung it's against WhatsApp ToS so I cannot guarantee anything. We're niche enough that they don't care IMHO, as long as you don't spam/scam people. It pretends to be the WhatsApp web client. I had my account locked for 48 hours once in 4 years of use, while experimenting with group creation which I guess made me look like a spammer; it has not occurred since. We have not had such locked account reports from users. Experimenting while developing is the "dangerous" part.
