WhatsApp's Business Platform went through significant changes between late 2025 and mid-2026: Meta restricted general-purpose AI chatbots from operating on WhatsApp, then had to walk that policy back after regulators in Italy and the EU intervened. At the same time, Meta launched a Calling API for businesses and completed the shutdown of the older On-Premises API. If you run a WhatsApp Business number for customer support, sales, or marketing in India, these changes affect what you can build, what you must migrate to, and what compliance risks to watch for.

The AI chatbot restriction and the regulatory pushback

In October 2025, Meta updated its WhatsApp Business terms to bar general-purpose AI chatbots — assistants like ChatGPT accessed through WhatsApp rather than Meta's own AI tools — from the platform. The stated goal was to prevent third-party AI products from competing directly with Meta AI inside WhatsApp's business messaging ecosystem.

That restriction did not survive unchallenged. In December 2025, Italy's competition authority ordered Meta to suspend the policy, arguing it risked shutting out rival AI services from a dominant messaging platform. By mid-2026, EU regulators went further, forcing Meta to reopen WhatsApp to third-party chatbots such as ChatGPT under antitrust pressure.

For Indian businesses, the practical takeaway is that the rules around embedding AI assistants inside WhatsApp flows are still being contested in different markets. If your business uses or plans to use a third-party AI layer on top of the WhatsApp Business API — for lead qualification, support automation, or product recommendations — treat this as an evolving area. Build your automation logic so it can adapt to platform terms changes without a full rebuild, and keep your integration vendor accountable for tracking Meta's changelog.

WhatsApp launches a Calling API for businesses

Meta introduced a Calling API that lets businesses initiate and receive voice calls with customers directly through WhatsApp Business Platform, alongside existing messaging. This extends WhatsApp beyond text, template messages, and catalog-based commerce into voice — relevant for businesses that currently rely on separate call centre infrastructure or click-to-call ads.

For sectors like collections, appointment reminders, insurance renewals, and high-value sales where a phone conversation converts better than a chat thread, this opens a new channel without asking customers to leave WhatsApp. Businesses evaluating this should check with their Business Solution Provider (BSP) on rollout timelines and pricing, since voice minutes are typically billed separately from conversation-based messaging pricing.

On-Premises API sunset: migration is no longer optional

Meta has completed the sunset of the On-Premises API, the self-hosted version of the WhatsApp Business API that many larger Indian enterprises used before the Cloud API existed. Businesses still running On-Premises infrastructure needed to migrate to the Cloud API or a BSP-hosted equivalent to keep their WhatsApp Business number active.

If your business (or your IT vendor) set up WhatsApp integration several years ago, confirm which API version you're currently on. Migration affects webhook configurations, media handling, and in some cases template approval history, so it needs a proper technical migration plan rather than a same-day switch.

What this means if you run WhatsApp Business in India

• Don't build critical customer journeys around a third-party AI chatbot embedded in WhatsApp without confirming current terms with your BSP — policy in this area has changed twice within a year.
• Ask your provider whether Calling API access is available for your account and what it costs before assuming it's bundled into your existing messaging plan.
• If you're still on the On-Premises API, migrate to Cloud API now — Meta has already sunset the older infrastructure, so delays risk service disruption.
• Keep an eye on conversation-based pricing categories, since Meta has continued adjusting how utility, marketing, authentication, and service conversations are billed heading into 2026.

Frequently asked questions

Can I still use ChatGPT or other third-party AI tools inside WhatsApp?

The rules have shifted more than once. Meta initially barred general-purpose AI chatbots in October 2025, but regulators in Italy and the EU forced changes to that policy. Check current terms with your BSP before building a dependency on any specific third-party AI integration.

What happened to the On-Premises WhatsApp Business API?

Meta has sunset the On-Premises API entirely. Businesses that were still running it needed to migrate to the Cloud API or a hosted BSP solution to keep their WhatsApp number operational.

Is the WhatsApp Calling API available to all businesses?

Meta introduced the Calling API as a new capability for the Business Platform, but rollout and billing details vary by provider. Confirm availability and pricing directly with your BSP rather than assuming it's included in your existing plan.

Does this affect WhatsApp Business API pricing in India?

Conversation-based pricing categories (marketing, utility, authentication, service) have continued to evolve alongside these platform changes. Review your latest billing statement or ask your BSP for the current category breakdown before budgeting for 2026.
