Wachat provides direct access to the WhatsApp Business Cloud API hosted by Meta, with zero proprietary middleware in the message path. That means every feature Meta ships — interactive flows, payments, secure messaging, message reactions, view-once media — reaches your account on the day it goes GA, not six months later. We are a vetted BSP, so onboarding uses Meta's Embedded Signup: the user clicks a button, completes Meta's consent flow, and a phone number is provisioned and verified in 5–10 minutes without any back-and-forth with Meta support.

Template management is the single biggest pain point in WhatsApp messaging, and we have spent two years instrumenting it. The template builder shows you the three categories (Utility, Marketing, Authentication), the pricing implication of each, character limits per component (1024 for body, 60 for headers), and a real-time linter that flags the language patterns most likely to get rejected. Approved templates appear in the inbox composer, in Flow Builder send nodes, and in the Broadcasts module without any extra publishing step.

Interactive messages — reply buttons, list pickers, CTA URL buttons, location requests, product catalogues — are first-class citizens. You can build them visually in the inbox, fire them from a flow, or send them via API with a 12-line JSON payload. Wachat handles the response routing automatically: a button click becomes a new conversation event with the button_id available to your rules engine, so a "Track Order" tap goes to the order-status flow without an agent in the loop.

Reliability is where most providers quietly fail. Wachat's send pipeline runs on a Kafka-backed queue with idempotent writes, exponential backoff on Meta's 429s, and per-number rate limiting that adapts to your tier (1K, 10K, 100K, unlimited). Inbound webhooks from Meta are deduped, persisted and replayed if your endpoint is down. Quality score, template rejection rate, opt-out rate and undelivered ratio are all surfaced in a dashboard with alert thresholds you set.
