Unify WhatsApp, Telegram & SMS.
Zero Downtime. Total Isolation.
Switch channels instantly. When you choose WhatsApp, Telegram, or SMS, your entire dashboard, API keys, logs, templates, and analytics dynamically adapt to that channel.
Three Dedicated Workspaces
Each channel lives in its own logical partition. No cross-contamination of templates, logs, or credentials.
WhatsApp API
Pair devices instantly via QR code using stealth browser automation, or connect officially via Meta WhatsApp Cloud API v20+ with HMAC webhook validation.
- ✓ Humanized typing delay & jitter
- ✓ Media attachments & interactive buttons
- ✓ Automated STOP / DND opt-out listener
Telegram API
Deploy official Telegram bots or connect verified client sessions via MTProto. Broadcast to large channels, manage group permissions, and ingest webhooks securely.
- ✓ Official Bot API & Token manager
- ✓ Secret token webhook verification
- ✓ Broadcast pacing to prevent 429 flood
SMS Gateway API
Route messages through your Android phone ("My Devices") with dual-SIM selection over WebSocket, or route via high-throughput HTTP SMS aggregators with automatic failover.
- ✓ Android SIM Gateway with offline queue
- ✓ Dynamic placeholder replacement ({PHONE}, {OTP})
- ✓ Real-time DLT & DND compliance
Unified Control Center
Experience how selecting a channel workspace reshapes the entire dashboard, navigation, and API environment.
WhatsApp vs. Telegram vs. SMS
Choose the right protocol for each use case, or broadcast simultaneously across all three with automated fallback.

Security Architecture
Engineered according to strict OWASP guidelines, multi-tenant isolation, and cryptographic storage standards.
Cryptographic Storage
Passwords hashed with bcrypt (cost factor 12). OTPs and API keys are stored exclusively as SHA-256 digests. Raw secrets are never stored or logged in plain text.
Multi-Tenant Isolation
Queries enforce tenant context resolution server-side. Every message, template, and log is partitioned by Organization and User ID with zero cross-tenant leakage.
Master IP Allowlisting
Enforce granular IP whitelists for API key usage, administrative dashboard access, and automated webhook ingestion with fast in-memory subnet checks.
HMAC-SHA256 Webhooks
Every outgoing webhook delivery carries an X-FunLoop-Signature cryptographic signature header, timestamp verification, and exponential backoff retry.
Integrate in Under 5 Minutes
RESTful endpoints with standard HTTP status codes, structured JSON responses, and predictable error schemas.

Loved by Developers & Marketers
"Having WhatsApp, Telegram, and SMS inside isolated workspaces completely solved our multi-channel routing mess. The Android SIM Gateway saved us over ₹40,000 in cloud SMS costs last quarter alone."
"The Anti-Ban governor and automatic STOP keyword detection are absolute lifesavers. Our WhatsApp numbers have zero suspension flags because of the warm-up governor and pacing jitter."
"The API documentation and HMAC webhook signature headers made integrating Fun Loop into our Node.js microservices seamless in less than an hour."
Got Questions? We Have Answers.
How does the workspace switcher work?
When you click on WhatsApp, Telegram, or SMS, the entire navigation bar, dashboard statistics, API keys, logs, templates, and settings switch to show only that channel. There is no mixing of data between different messaging channels.
Can Fun Loop guarantee my WhatsApp number won't be banned?
No system can realistically guarantee that an external provider will never ban an account. What Fun Loop does is drastically reduce suspension risks through humanized typing delays (2-5s), batch pacing jitter (4-12s), new account warm-up ramping, automatic STOP/DND opt-out removal, and campaign circuit breakers.
How does the Android SIM Gateway ("My Devices") work?
You connect your Android phone to our platform via a secure WebSocket connection. When your system sends an SMS via API, our server routes it directly to your phone, which sends the SMS using your local SIM card. If the phone is offline, messages are automatically queued in the database until reconnection.
Is my GST number and company data secure?
Yes. Fun Loop APIs runs on Windows Server IIS with Microsoft SQL Server. All passwords use bcrypt hashing, sensitive credentials are encrypted using AES-256-GCM, and the database supports Always Encrypted storage.
