your customers live on.

Unified billing

One invoice. Per-channel meter. No contract juggling.

Unified webhooks

Same signature scheme. Same replay semantics. Every event.

Unified logs

Search across channels, filter by conversation, replay in the dashboard.

Positioning

Twilio sells sendSMS().
Zaptick sells the whole marketing stack.

Channels are a commodity — the orchestration above them isn't. Zaptick gives you every channel (WhatsApp, Email, SMS, Voice, RCS) plus the entire marketing OS on top — campaigns, workflows, agents, commerce, analytics — in one typed SDK.

Without Zaptick

The stitched stack

You stitch together 5 services and a week of plumbing

Twilio + Plivo

for SMS across regions

SendGrid or Resend

for transactional email

Bird / Gupshup / Wati

for WhatsApp Business

Vapi + Retell

for voice AI agents

Zapier / Make / cron

to glue it all together

OpenAI + pgvector + RAG

for the chatbot layer

Razorpay + webhooks

for payments inside threads

Segment + custom DB

for attribution & ROI

With Zaptick

One SDK. Typed end-to-end.

Every piece of the marketing stack, same auth, same error shape, same rate-limit budget.

Primitives

Beyond channels. The full marketing OS.

Channels get messages out. These are the primitives that turn messages into real marketing — campaigns, workflows, agents, commerce, intelligence.

What devs ship with Zaptick

Real products. Real code. Real outcomes.

These aren't hypotheticals. They're patterns pulled straight from Zaptick customers — with the code you'd actually write.

E-commerce

real pattern from a real customer

D2C brand recovers 34% of abandoned carts — at 2 AM

34%cart recovery

Customer adds a ₹4,999 kurta and bounces. Shopify fires a webhook to your Next.js route handler. You wait 30 minutes, send a template with the product image + 10% coupon + one-tap checkout. She buys at 2 AM from bed. The follow-up order-status updates are on the same SDK.

Developer experience

DX details that actually matter.

We borrowed the best from Stripe, Resend, and Clerk — and adapted it for marketing infrastructure. Here's what you don't have to build yourself.

P99 latency < 200ms

API served from edge locations in Mumbai, Singapore, and Frankfurt. Real-time dashboards don't lie.

Typed end-to-end

Every request, response, and webhook is strongly typed. IntelliSense for every method and field.

Automatic retries

Built-in exponential backoff on 429 and 5xx. You never write try/catch around rate limits again.

Typed webhooks

Publish & subscribe pattern with signed payloads. Replay any event for local debugging.

Idempotent by default

Every mutation accepts an idempotency key. Safe retries, guaranteed once-only delivery.

Secure by design

Publishable + secret keys, key rotation, scoped permissions, signed webhooks — Stripe-level primitives.

OpenAPI 3.1

Every endpoint auto-documented. Generate clients in 40+ languages. Postman and Insomnia collections included.

Zero runtime deps

The Node SDK uses native fetch. 11KB gzipped. Works on Bun, Cloudflare Workers, Deno, and Node 18+.

Engineers shipping on Zaptick

Built by developers. Loved by developers.

"We replaced Twilio + Wati + three custom cron jobs with one SDK. Our WhatsApp ops went from 2,000 lines of glue code to about 80."

"The typed webhooks are absurd. Every event has IntelliSense. I haven't had a production webhook bug in 4 months."

"Set up WhatsApp Pay with Razorpay in an afternoon. The SDK handles Meta's ToS handshake, webhook retries, refund API — all of it."
