TL;DR: WhatsApp error 131064 means your account has reached a messaging limit because of repeated template classification violations (templates categorized incorrectly, e.g. marketing content submitted as utility). Meta's
detailsstring is "Message failed to send because this account has reached its messaging limit due to template classification violations. This applies to both template messages and direct send messages." The restriction lifts automatically after the enforcement period; correct your classifications.
What Error 131064 Means
131064 is a throttling/enforcement error. When a business repeatedly misclassifies template categories (Marketing / Utility / Authentication), Meta applies a progressive messaging limit. Meta's official details value is:
"Message failed to send because this account has reached its messaging limit due to template classification violations. This applies to both template messages and direct send messages."
As 360dialog's reference summarizes it, the business has exceeded the threshold for template-category misclassification strikes and is being rate-limited as part of Meta's progressive enforcement. Crucially, it blocks both template messages and direct send messages — not just the offending templates. Meta states the restriction is automatically lifted after the enforcement period (Meta does not publish a fixed duration; do not assume a flat 24-hour reset).
Where You See It
Synchronous /messages response when you attempt to send while the limit is in effect. Because it's account-scoped, all sends are affected, not just one template.
Common Causes
- Submitting marketing content under a utility or authentication category to dodge pricing/limits.
- Repeated category-correction strikes after Meta re-categorized your templates.
- A pattern of misclassification across multiple templates pushing the account past the enforcement threshold.
How to Fix It
- Review every template's category in WhatsApp Manager and confirm content matches the category (promotional → Marketing; transactional/account updates → Utility; OTP → Authentication).
- Re-create or re-categorize misclassified templates correctly.
- Wait out the enforcement period — Meta lifts the restriction automatically; you don't appeal a fixed window.
- See Meta's Template quality and Template categorization docs for category rules.
How to Prevent It
- Categorize honestly at creation; don't label marketing as utility.
- Monitor
template_category_updatewebhooks so you know when Meta re-categorizes a template. - Periodically audit template content against current categorization guidelines.

How Dualhook Helps
Honest answer: the trigger (sending) and the fix (correct categorization) live in your stack and Meta's tools — Dualhook is not in the message-send path and never reads message content. But because Dualhook holds advanced whatsapp_business_management access, it can surface template state and category-update signals, helping you spot misclassifications and Meta re-categorizations before they accumulate into a 131064 limit. See Templates, Template Analytics, and Capacity, Quality & Limits. The re-categorization itself is done in WhatsApp Manager.
