Wachat is a Meta-vetted BSP. Onboard your number through Embedded Signup, ship Meta-approved templates the same day, and start using interactive lists, buttons, CTAs and media without writing a single integration. Webhooks, retries and quality monitoring are handled for you.
Teams sign up for the WhatsApp Business API expecting "WhatsApp, but for business". What they get is a Meta Business Manager interface that assumes you already know what an HSM is, a Cloud API that returns cryptic error codes, and a 24-hour service window rule that gets you blocked the first time you try to message a customer who hasn't replied in two days. Templates get rejected for vague reasons. Quality scores drop without explanation. A junior marketer accidentally messages 5,000 non-opted-in contacts and the number gets restricted.
Meanwhile, the developers are stuck building retry queues, webhook validators, media uploaders and template variable mappers — work that has nothing to do with the actual product. Six weeks in, the messaging stack is a brittle Node.js script on someone's laptop, and the only person who understands it has just resigned.
Wachat is the layer that absorbs all of this. We are a Meta Business Solution Provider, so the API quotas, template review queue, embedded signup and quality monitoring sit inside our infrastructure. You get a clean API and a UI that maps every WhatsApp concept — service window, HSM categories, opt-in, button vs list, media MIME types — to a workflow your team can actually run.
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.
Customers click "Connect WhatsApp", complete Meta's native consent flow in a popup, and a verified number is live in 5–10 minutes. No PIN sharing, no Business Manager access requests, no waiting for a CSM to provision an account.
Author Utility, Marketing and Authentication templates with live validation. The linter flags promotional language in Utility templates, missing opt-out in Marketing, and incorrect placeholders. Submitted templates show Meta review status with reason codes.
Drag-and-drop builder for reply buttons (up to 3), list messages (up to 10 sections), CTA URL buttons, location requests and product list messages from your Meta catalogue. Preview renders exactly like the WhatsApp client on iOS and Android.
Every contact has a live service-window countdown and an opt-in record (source, timestamp, channel). Sending outside the window forces a template selector; sending without opt-in is blocked at the API level with a 422 response.
Upload images (JPG, PNG up to 5 MB), video (MP4, 3GP up to 16 MB), documents (PDF, DOC, XLS up to 100 MB), audio (AAC, MP4, MPEG up to 16 MB) and stickers (WebP). Wachat handles MIME validation, Meta resumable upload and CDN caching.
Per-number quality score (green/yellow/red), messaging tier (1K to unlimited), and template rejection rate stream into a dashboard. Alerts fire when quality drops to medium or when daily opt-outs exceed your threshold, with playbook links to remediate.
Wachat fans out Meta webhooks to your endpoints with retry-with-backoff for 5xx responses, signed HMAC headers, and a 7-day replay log. You can fork a single Meta event to your CRM, your data warehouse and a Slack channel from one config.
A fashion D2C brand sends a Marketing template with the cart image, a "Resume Checkout" CTA URL button and a 10% off code 30 minutes after abandonment. Conversions recovered: 18% on first send, another 6% on a follow-up at hour 24 — all running inside the WhatsApp 24-hour window opened by the initial reply.
A neobank moves SMS OTPs to WhatsApp Authentication templates: 60% cheaper per message, 4× higher open rate, and a one-tap copy button. The template is rate-limited per user, fingerprinted to the device, and falls back to SMS only if WhatsApp is undelivered after 15 seconds.
A diagnostics chain sends a Utility template 24 hours before each appointment with reply buttons "Confirm", "Reschedule" and "Cancel". Button taps route into the booking flow without an agent; no-show rate drops from 22% to 9%, freeing 14 hours of phone-confirmation labour weekly per branch.
An online coding bootcamp uses list messages to let students pick which cohort track to enrol in, then sends Utility templates for assignment deadlines and grading feedback. Completion rate on the second cohort jumped 31% versus the email-only cohort, with cost-per-completion down 24%.
A 3PL provider triggers Utility templates at every status change — picked, in-transit, out-for-delivery, delivered — with a CTA URL button to the live tracking page. WISMO ("where is my order") inbound tickets fell 64%, and proof-of-delivery photos are returned via WhatsApp media in the same thread.
WhatsApp Business API is included on every SabNode workspace. No separate billing, no extra setup — flip it on from your workspace settings.
Click "Connect WhatsApp" in Wachat. Meta's popup walks the business owner through verifying the Meta Business, selecting a number and accepting terms. Provisioning finishes in 5–10 minutes.
Use the template builder to draft 3–5 starter templates: a welcome Utility, a Marketing offer, an Authentication OTP. Meta reviews them in 1–24 hours; the linter pre-catches most rejection reasons.
Add a WhatsApp opt-in checkbox to your checkout, signup form or web widget. Wachat records source, timestamp and IP, and exposes a single API to verify opt-in before any outbound send.
Send your first templates from the inbox, a flow or the Broadcasts module. Watch the delivery dashboard for sent, delivered, read, replied and failed. Address any quality dips before scaling volume.
Meta auto-graduates well-behaved numbers from 1K to 10K to 100K to unlimited daily unique recipients. Wachat surfaces tier-up triggers and the metrics you need to maintain a green quality score.
