I know this question has been asked before, but it's been about 4-5 years since the latest responses and I think those solutions or even the library itself are not working anymore.
How to send a message to a Whatsapp group using yowsup library?
Assume I have properly installed the library from here in a Raspberry Pi 3b+. I can send a text message to a single phone number using yowsup-cli demos -c config -s xxxxxxx "message", but cant send it to a group using the GJID (failed to fetch keys for [email protected] error).
Can you confirm that this is still possible or do you know a better alternative?
Since some days, you cant send messages to groups. An issue on Github is opened. We have to wait.
