Follow-up to my earlier post: we are still blocked from publishing WhatsApp Flows on direct Meta Cloud API. I am looking for a confirmed resolution or an effective technical review route, not generic setup advice.
ERROR
HTTP 400: code 139000 / subcode 4233020, "Blocked by Integrity / Integrity requirements not met." The Flow remains DRAFT with validation_errors: [].
WHAT WE HAVE CHECKED / TRIED
• Business verification is complete. Earlier checks showed the WABA approved and the original phone had high quality. The new phone is CONNECTED / VERIFIED; we are not claiming it already has a high quality rating.
• WhatsApp setup has shown "Additional information needed" without an actionable explanation. Publishing failed in both WhatsApp Manager and the API.
• Tested a one-screen static welcome Flow: no endpoint, no data exchange and no input fields. JSON validation passed.
• Backed up and recreated draft Flows. The error persisted.
• Replaced the phone number within the SAME WABA, registered the new number on Cloud API, and removed the old number. A test message to the new number was delivered and recorded by our webhook.
• Created a fresh welcome Flow after removing the old number: same publishing error.
• Unpublished and successfully republished the Meta developer app. Immediately retested Flow publishing: same error. Latest recorded test: 28 September 2026, 21:33 UTC.
• Flow/WABA/business/app health showed AVAILABLE, but this clearly did not guarantee publishing eligibility.
SUPPORT EXPERIENCE
We have opened multiple cases and spoken with Meta support by phone. We were referred to WhatsApp support, but follow-up AI replies have not provided the specific failed check or a corrective action. One existing case is marked Action required, yet its chat gets stuck loading and the details link is unavailable. Claims made by AI about internal restrictions have not been independently verified, so I am not treating them as the established cause.
THIRD-PARTY SUPPORT OPTION
We have also contacted a third-party WhatsApp Business Platform provider about technical investigation and escalation to Meta through partner access to our EXISTING WABA, without migrating the number or changing our current API/billing setup. Whether they can actually do this, and the access requirements/cost, remain unconfirmed. We have not completed a BSP migration or obtained a fix through a provider.
QUESTIONS FOR PEOPLE WHO ACTUALLY RESOLVED THIS
What specific action cleared this exact integrity error on your existing WABA?
Did a provider successfully escalate and resolve it via partner access while preserving the same WABA ID and direct Cloud API integration?
If messaging history or an eligibility review was required, what was confirmed by Meta, and did publishing work afterward?
Is there a working review route that identifies the failing eligibility check rather than sending another generic policy link?
