How it works under the hood
Every message follows an async pipeline optimized to never drop conversations, even during traffic spikes.
01
WhatsApp Cloud API webhook
Meta sends each inbound message to our secure endpoints. We validate the signature, normalize the payload, and enqueue it instantly.
02
Message queue
Messages enter distributed queues per tenant. We prioritize active conversations and prevent blocking during bulk campaigns.
03
AI engine & flows
The engine runs your visual flows or configured AI agent. It processes text, voice, images, and PDFs depending on your plan.
04
User response
Replies are sent via WhatsApp Cloud API with automatic retries and exponential backoff if Meta returns a transient error.
05
CRM sync
Each interaction is reflected in your CRM (Chatwoot or other integrations) and triggers webhooks to your external systems.
Reliability & security
Distributed infrastructure with monitoring, auto-scaling, and data protection at every layer.
RETRIES
Smart exponential backoff
If a send fails due to a temporary network or Meta error, we automatically retry with increasing intervals until delivery completes.
QUEUES
Distributed async processing
No message blocks another. Queues decouple reception and processing to absorb spikes without degrading the experience.
AVAILABILITY
High availability & auto-scaling
Distributed infrastructure with redundancy across multiple zones, real-time monitoring, and workers that scale with demand. 99.9% uptime target.
MULTI-TENANT
Per-account isolation
Each bot and workspace runs in its own context. A spike in one account does not affect performance for others.
ENCRYPTION
Data encrypted in transit and at rest
All communications use TLS 1.2+. Sensitive data is stored encrypted in managed databases with restricted access.
WEBHOOKS
Verifiable HMAC signatures
Every event sent to your endpoint includes a cryptographic signature so you can verify it comes from BuilderBot Cloud.
For developers
Integrate BuilderBot Cloud into your stack with REST API, webhooks, and technical documentation.
WEBHOOKS
Real-time events
Receive notifications for inbound messages, status changes, and flow events. Configure retries and dead-letter for debugging.
RATE LIMITS
Transparent limits
X-RateLimit-* headers on every response. Per-session queues prevent bursts that compromise WhatsApp deliverability.
SCALE WITH CONFIDENCE
Infrastructure ready for your next million messages
