Stop Waiting Weeks —Go Live on WhatsApp in minutes with Spellty Messaging API
Updated 16 July 2025
Before diving in, here’s a quick reality‑check: configuring a stand‑alone WhatsApp Business API directly through Facebook can be a lengthy, multi‑step process—business verification, phone‑number approval, Facebook for Developers setup, and manual webhooks. With Spellty Messaging API, you skip most of that. All you need is a verified Meta Business Suite account (formerly Facebook Business Manager) with an approved WhatsApp number; Spellty takes care of template submission, webhooks, and infrastructure behind the scenes. Once your number is live inside Meta Business Suite, you can start sending messages through Spellty in minutes instead of weeks.
1 · Why add an API to WhatsApp?
Most customers already rely on WhatsApp for order updates, support, and quick promotions. The Spellty Messaging API exposes that same channel programmatically so your back‑end or CRM can:
| Business goal | What the API does |
|---|---|
| Cut response time | Trigger automated replies to FAQs or order‑status requests in seconds. |
| Keep users informed | Push transactional alerts—e‑receipts, delivery updates, payment reminders—and track delivery status via webhooks. |
| Personalise at scale | Merge dynamic fields (name, order ID, due date) into pre‑approved templates. |
2 · Core capabilities (v1.0)
| Feature | Details |
|---|---|
| Send approved templates | Single /messages endpoint for text, media, or document templates. |
| Delivery webhooks | Real‑time callbacks for queued, sent, delivered, and read events. |
| Media support | Attach images, PDFs, audio, or video up to WhatsApp’s current size limits. |
| Number management | Map multiple verified senders to one Spellty project and tag traffic by brand or product line. |
| Basic analytics | Pull per‑template counts (sent / delivered / failed) via REST or view them in the Spellty dashboard. |
| On the roadmap | SMS & email endpoints (beta Q4 2025) and contact segmentation (2026). |
No built‑in CRM connectors (yet).
Integrations with HubSpot, Salesforce, or Zendesk require middleware (Zapier, iPaaS) or direct API work.
3 · Typical use cases
| Sector | Workflow enabled by the API |
|---|---|
| E‑commerce | Abandoned‑cart nudge → order confirmation → shipping updates. |
| Logistics | Driver‑on‑the‑way alerts plus proof‑of‑delivery images. |
| Fintech / Banking | Transaction receipts or low‑balance alerts (use Spellty OTP API for one‑time passwords). |
| Customer support | “Ticket received” acknowledgement with a deep link to your portal. |

Most teams complete a basic integration in 2–3 developer days once their WhatsApp number is approved.
5 · Security & compliance
| Aspect | Spellty approach |
|---|---|
| Transport security | HTTPS (TLS 1.2+) for all API and webhook traffic. |
| Message content | End‑to‑end encrypted within WhatsApp—Spellty never decrypts it. |
| Data retention | Message metadata stored 30 days by default (configurable up to 12 months). |
| GDPR/CCPA | Data‑subject access and deletion endpoints available via support ticket. |
6 · Current limitations
- Group chats and bulk “blasts” require pre‑approved templates.
- Attachment size capped by WhatsApp (64 MB documents, 16 MB video).
- Rate limits follow Meta’s tiering (24‑hour customer‑initiated vs. template windows).
- Native CRM plugins, multi‑channel messaging, and advanced segmentation are on the roadmap.
7 · Getting started
- Verify your business in Meta Business Suite and register a WhatsApp number.
- Create a project in the Spellty dashboard and link your number.
- Generate an API key and whitelist your webhook URL.
- Send your first template with cURL or Postman (docs at
docs.spellty.com/messaging).
