    Invite people to a group

    POSThttps://api.batzap.com/v1/groups/{jid}/invite

    Adds people to a group the best way possible: first directly, and for anyone whose privacy settings block that, it sends the invite link by direct message.

    At most 20 numbers per call; duplicates are removed. People who are already members or have no WhatsApp are reported, not messaged.

    Invite DMs appear in the inbox like any other message. The response is success: false when at least one number failed.
