Hi @IWCFL,
Welcome to the Community.
There is no direct integration between Discord and WhatsApp on Zapier, and WhatsApp's API is private. Only the WhatsApp Business API is supported for medium and large businesses. Additionally, using Discord as a trigger in Zapier requires administrative server permissions, which are currently unavailable, as you mentioned above. Alternatively, consider using supported apps like Slack, Telegram, or email to receive notifications based on Discord activity.
I hope this helps. Let me know if you have any other questions.
