For questions about the WhatsApp protocol (like how to send a specific type of message), you can also use the WhatsApp protocol Q&A section on GitHub discussions.
The godoc includes docs for all methods and event types. There's also a simple example at the top.
Most core features are already present:
- Sending messages to private chats and groups (both text and media)
- Receiving all messages
- Managing groups and receiving group change events
- Joining via invite messages, using and creating invite links
- Sending and receiving typing notifications
- Sending and receiving delivery and read receipts
- Reading and writing app state (contact list, chat pin/mute status, etc)
- Sending and handling retry receipts if message decryption fails
- Sending status messages (experimental, may not work for large contact lists)
Things that are not yet implemented:
- Sending broadcast list messages (this is not supported on WhatsApp web either)
- Calls
