What WhatsApp business API development actually requires in 2026
2026 stack: Meta Cloud API (free) for direct, Twilio + 360dialog + Vonage for BSP-mediated with extra features, Node + Express or NestJS backend, Postgres for conversation state, Redis for short-term context. Multi-tenant: separate phone-number per tenant or shared with tagging. WhatsApp API engineers must understand template approval workflow (Meta reviews every marketing template), the 24-hour customer-care window (free vs paid messages), and number-quality scoring. Generic backend engineers underestimate the operational complexity.
