Meta Error Codes & Troubleshooting
When delivering high-volume WhatsApp broadcast campaigns, Meta’s Cloud API enforces delivery limits, quality ratings, and spam protections.
Understanding Meta’s error codes helps merchants protect their phone number health and maintain high delivery rates.
Phone Number Quality Ratings
Meta assigns every WhatsApp Business phone number a real-time Quality Rating visible in your Galaxa Nova Dashboard:
- Green (High Quality): The account is operating normally with high message engagement and low user block rates.
- Yellow (Medium Quality): A small increase in user blocks or spam reports has occurred. Review recent broadcast copy and audience targeting.
- Red (Low Quality): Multiple recipients have reported or blocked your number. Meta may restrict daily messaging limits until engagement improves.
Brand Safety Safeguards
Nova includes built-in safeguards to ensure your phone number remains in the Green tier:
- Automatic Unsubscribe Handling: Any customer who replies with words like “STOP”, “UNSUBSCRIBE”, or “REMOVE” is immediately opted out of future promotional campaigns.
- Inbound Support Suppression: If a customer opens a live support inquiry with your brand while a marketing retry is pending in the queue, Nova immediately suppresses the marketing message to avoid customer frustration.
- Wholesale Spend Cap: Hard limits prevent unintentional mass dispatches that could harm your sender reputation.
