WhatsApp Business API · Nearshore
WhatsApp Business Integration Built to Last in Production
Not a Zapier workflow. A typed, monitored, cost-controlled API integration with permanent system user auth, a proper message store, and a team available in your timezone when it breaks at 2 PM on a Tuesday.
What's Included
System User Authentication
Permanent system user tokens managed as infrastructure secrets — no manual rotation, no temporary tokens expiring in production. Meta Business Manager configuration included.
Message Routing Layer
Inbound webhook handler with signature verification, message deduplication, and retry-safe idempotency keys. Typed payload parsing at the boundary so downstream code never touches raw JSON.
PostgreSQL Message Store
Full conversation history with Drizzle ORM — thread model, message status tracking (sent / delivered / read / failed), and contact enrichment. Schema migrations are versioned and reversible.
Role-Based Access Control
Distinct permissions and rate limits per tier — agent, supervisor, API client. A business rule that lets supervisors override an agent's thread but blocks agents from accessing another agent's queue is a 3-line policy file, not a forked workflow.
Cost Controls & Quota Management
Real-time tracking of conversation-based pricing against your WhatsApp Business budget. Automatic throttling when approaching the quota threshold. Quota-increase request flow with audit trail.
Analytics & Monitoring
Dedicated health-check endpoints, structured message analytics (volume, response time, resolution rate), and alerting on delivery failures. Not workflow execution logs.
A Legitimate Question
Why Not Just Use n8n?
Tools like n8n, Make, and Zapier are legitimate for prototyping a WhatsApp integration or handling low message volume. They get you a working webhook fast. The problems show up later — when the business depends on this system and nobody's confident touching it anymore.
| Aspect | No-code / automation tools | Palo Duro AI |
|---|---|---|
| Access tokens | Manual rotation; temporary tokens often left in place | System user + permanent token, managed as infrastructure secrets |
| Data layer | Flat, whatever the connector supports | PostgreSQL with typed schema, Drizzle ORM |
| Business logic | Visual workflow branches | Role-based access control with distinct permissions and rate limits per tier |
| Cost control | None built-in — scales unmanaged with volume | Real-time budget tracking, automatic throttling, quota-increase flow |
| Architecture | Single workflow tool, vendor-locked | Monorepo, containerized, deployable independently |
| Caching | Not applicable | Query/response caching to reduce redundant calls and rate-limit exposure |
| Data contracts | Loose JSON between nodes | DTOs at every service boundary — typed, validated, versioned |
| Monitoring | Workflow execution logs | Dedicated health-check endpoints, structured analytics, alerting |
This isn't theoretical — it's the architecture running in production for WAGO México's distributor network today. Read the case study.
