Features

Everything a developer needs from a WhatsApp API

Aumfig API is built for shipping — REST endpoints, webhooks, trigger URLs, and bulk WhatsApp sending without the enterprise pricing or Meta verification queue.

Simple REST API

One endpoint to send messages, media, and bulk campaigns. JSON in, JSON out. Examples in any language.

Multi-user accounts

Each user gets their own WhatsApp session, API key, trigger URL, and isolated message history.

Anti-ban layering

25s base + 1–10s random jitter between sends, humanized typing, duplicate-message guard, hourly caps, and pre-send number validation — multiple layers keep your account safe.

Bulk & broadcast

One Broadcast screen for everything — pick groups, saved contacts, or paste/import a CSV of numbers. Personalize with {{name}} and {{phone}}. Up to 500 per request via the API.

Webhooks & triggers

Outbound webhooks for events. Inbound trigger URLs to fire messages from Razorpay, Shopify, n8n, Zapier.

Secure by default

API keys, HMAC-signed webhooks, JWT cookies, and HTTPS everywhere. Your data stays yours.

Scheduled messages

Pick a date and time → message goes out automatically. Perfect for birthday wishes, fee reminders, follow-ups, festival offers.

Number Finder

Bulk-validate up to 500 numbers in one go — see which contacts actually have WhatsApp before you send. Export clean lists as CSV.

Smart Send Window

Configure send hours (e.g. 9 AM – 9 PM) and off-days. Outside the window, messages defer — never spam customers at 2 AM.

Live queue

Watch your messages flow through the rate-limit queue in real time — see what's pending, who's next, and what's been sent.

Contact book

Save your VIP list once and reuse it everywhere. Bulk-import from a spreadsheet, tag & search, then broadcast by contact id. Basic 100, Pro 300 saved contacts.

Broadcast to groups + contacts

Send the same message to up to 100 recipients in one call — any mix of WhatsApp groups and saved contacts. Mass announce sales, alerts, and updates fast.

CSV upload

Drop a CSV with phone,name rows and Aumfig parses, validates, and queues the campaign. Sample CSV included.

Refer & save 50%

Every user gets a personal referral link. Friends who sign up via your link get 50% off their first month. No limits, instant.

3-day free trial

Test everything risk-free for 3 days, 50 messages/day. No card required. Upgrade anytime to unlock unlimited sending.

About Aumfig

An unofficial WhatsApp API built for the 99%.

The official WhatsApp Business API costs $2,000+/month minimum spend, takes weeks of Meta verification, requires a Business Solution Provider, and locks you into a maze of pricing tiers for "conversation categories."

We built Aumfig API because most businesses don't need any of that. They need a simple way to send WhatsApp messages from their app, their store, their CRM, their spreadsheet — and they need it to just work today, not next month.

Our mission

Give every developer and small business owner the same WhatsApp superpowers that only enterprises could afford — for the price of one Netflix subscription.

Built for speed

Account → connected WhatsApp → first sent message in under 5 minutes. No vendor calls, no contracts, no waiting.

Honest pricing

One flat rate. No per-message billing, no conversation tiers, no marketing-message surcharges. Send as much as the rate limit allows.

Developer-first

Clean REST API, copy-paste curl examples, code samples for Node, Python, PHP, Apps Script. Built by people who ship code.

Your data stays yours

We don't read, store, sell, or analyze your messages. JWT cookies, HMAC-signed webhooks, HTTPS everywhere. Open about what we use.

Built for the people who actually wire WhatsApp into apps

Indie hackers, agencies, and product teams who got tired of waiting on Meta Business API approval — and the bills that follow.

Spent two weeks waiting for Meta Business API approval, then 30 minutes wiring up Aumfig instead. Order confirmations are out the door — and the bill is sane.

The Apps Script integration is brilliant. A non-technical client of mine sends bulk reminders from a Google Sheet without ever opening a code editor.

Webhooks with HMAC signatures, rate-limit headers, and a tidy REST surface. It feels like an API that was built by someone who has actually consumed APIs.

Honest pricing, honest docs. They tell you upfront this is unofficial and how to use it safely. Best $20 I spend every month.

My WhatsApp didn't get banned even after sending thousands of messages. The 25-second delay and batch rests actually work — way safer than other gateways I tried.

FAQ

Aumfig API — frequently asked questions

Is this an official WhatsApp API?

No — this is an unofficial WhatsApp API. We use the multi-device protocol under the hood, similar to how WhatsApp Web works. It is not the WhatsApp Business API (Meta's paid official offering) and is not affiliated with or endorsed by WhatsApp Inc. or Meta Platforms. Use at your own risk; for mission-critical regulated workflows, consider the official Business API.

Is there a free trial?

Yes. Every new account can start a 3-day free trial with a 50-message-per-day limit. No card required. After the trial ends you'll need to subscribe to continue sending.

Why is my first month cheaper?

We offer first-time buyers $20 for the first month so you can try the gateway risk-free. From the second month onwards, the standard $25 price applies.

How do coupon codes work?

If you have a coupon code, enter it in the pricing card and click Apply. Valid codes give an extra discount on top of any first-time-buyer pricing. One coupon per checkout.

What payment methods are supported?

We use Razorpay, which supports UPI, credit & debit cards, net banking, and wallets. All payments are secure and PCI-compliant.

Will my WhatsApp get banned?

We use the official multi-device protocol and enforce a 25-second delay between messages with periodic batch rests. As long as you don't spam, your account stays safe.

Can I cancel my subscription?

Yes. There's no contract — your access expires at the end of the paid month. To renew, simply subscribe again.

Do you offer refunds?

All sales are final. We do not offer refunds once payment is completed. Please try the free trial before purchasing to make sure the service meets your needs.

Will my WhatsApp number be safe?

We never store your messages or contact lists. Sessions are encrypted with WhatsApp's standard signal protocol. To minimize ban risk, we enforce a 25-second delay between messages and rest periods after batches — the same patterns a human follows.

How does Aumfig compare to Twilio, Vonage, or other gateways?

Twilio, Vonage, MessageBird and similar BSPs resell the official WhatsApp Business API — so they share its constraints: weeks of Meta approval, business verification, pre-approved templates, and per-message charges that can hit $0.05–$0.15 each plus a session/conversation fee on top. Aumfig is built on the multi-device protocol instead: no Meta approval, no template review, no per-message billing. Just a flat $20–$30/month no matter how many messages you send (within rate limits). The trade-off: no green tick and not a fit for regulated industries — but a perfect fit for SMBs, indie hackers, and internal tools.

What if I scale beyond Aumfig?

If you grow to needing the green tick, regulated conversation categories, or 50,000+ messages a day, we'll happily help you migrate to the official Meta Business API. No lock-in.

Get your first WhatsApp message out in 5 minutes.

No credit card to start. No corporate approvals. No waiting weeks for Meta. Just sign up, scan a QR, and ship.
