Best WhatsApp API Platform in India 2026 | ZazzyAgent vs WATI vs AiSensy vs Interakt vs Gallabox (Full in depth Comparison)
Choosing the wrong WhatsApp API platform costs you money every single month — not just in subscription fees, but in the hidden markup most platforms add on top of Meta's conversation charges, the features you pay extra for, and the leads you lose because the platform wasn't built for how Indian businesses actually operate.
This is a direct, honest comparison of the five most widely used WhatsApp API platforms in India: ZazzyAgent, WATI, AiSensy, Interakt, and Gallabox.
The One Question Most Comparison Articles Don't Ask
Before comparing features, ask this: how much markup does this platform add on top of Meta's message charges?
Meta publishes official per-message rates for India. Every BSP (Business Solution Provider) passes these charges on to their clients — but most of them add their own markup on top. That markup is pure profit for the platform, and it compounds with every message you send.
| Platform | Markup on Meta Messages |
|---|---|
| ZazzyAgent | 0% |
| WhatChimp | 0% |
| AiSensy | 20–60% (varies by template type and plan) |
| WATI | ~20% |
| Interakt | ~15–20% |
| Gallabox | ~15% |
On 50,000 marketing messages per month at Meta's India rate of ~₹0.78/message, you'd pay:
With ZazzyAgent: ₹39,000 (Meta's price)
With AiSensy (40% avg markup): ₹54,600
With WATI (20% markup): ₹46,800
The annual difference between ZazzyAgent and AiSensy on this volume alone: ₹1,87,200.
That's the hidden cost most comparison articles skip. Let's look at the full picture.
