On-Premises API Sunset

    On-Premises API sunset

    The final supported version of the On-Premise API client expired on October 23, 2025. On-Premises API can't be used to send messages to WhatsApp users anymore. Please use Cloud API on the WhatsApp Business Platform instead.

    Why Cloud API?

    Since its launch in 2022, Cloud API has seen strong adoption and better performance than On-Premises API. Some of the reasons for this include:

    • Cost-effective: Reduced setup, hosting and maintenance costs. For example, some partners have experienced a 90%+ reduction in infrastructure costs after moving to Cloud API.
    • More Scalable: Cloud API is our fastest throughput platform, offering up to 1,000 messages per second (4x the level of On-Premises API).
    • Better Reliability: Cloud API consistently experiences 99.9% uptime and < 5 seconds p99 latency. View our WhatsApp Business API Status Page for uptime and latency statuses.
    • Secure and certified: Cloud API has enterprise-grade security features and certifications, including GDPR and LGPD compliance, SOC2 and SOC3 certification, and we are currently pursuing ISO 27001. See our Cloud API Compliance Center and our security and encryption whitepapers.
    • Local storage options: Cloud API now supports local storage, giving you the option to control where message data is stored at rest.
    • Cloud-only features: Cloud API offers more functionality than On-Premises API, with newly released functionality and upcoming functionality only available on Cloud API.

    With these enterprise-grade messaging foundations in place, we have decided to transition to a fully cloud-hosted WhatsApp Business Platform.
