I'd need more specifics to give you a proper diagnosis-there are a few layers here that could be causing the bans.
First off, how are you connecting? Is it a coexistence setup where you still have access to a standard WhatsApp Business app alongside the API? That alone can flag things if Meta detects conflicting sessions.
Are you on the full API or using something like the WhatsApp Business Platform via a BSP? GoHighLevel typically acts as a middleware, so if their IP ranges or device fingerprints get flagged, every account routed through them suffers.
How many outbound conversations per day are we talking? Even with a verified WABA, if you're pushing beyond what Meta considers "normal" for your account age or industry, the automated triggers start firing.
Meta rarely gives detailed feedback on bans-just a generic "violation" message. But the invisible signals include device IDs, IP blocks associated with the admin's Facebook account, and even the browser fingerprint of whoever manages the WABA. If you're spinning up multiple numbers from the same physical device or same ISP subnet, that's a red flag.
Can you share your connection type, concurrency volume, and whether each number has its own dedicated device? That might help spot the pattern.
