WhatsApp's Business Platform saw several substantive changes through 2025: a new Calling API that lets businesses initiate voice calls, a globally available Meta AI agent for customer service, expanded discoverability tools for finding businesses and channels, and the continued sunset of the legacy On-Premises API in favour of the Cloud API. If you run a business on WhatsApp in India, these changes affect how you set up messaging, budget for support, and plan customer engagement.

WhatsApp adds a Calling API for businesses

Meta introduced a Calling API that allows businesses to initiate voice calls with customers directly through WhatsApp's Business Platform, extending the channel beyond text and template messages. This is a meaningful shift: until now, voice interaction on WhatsApp for businesses was largely limited to customers calling in, not businesses proactively reaching out by voice through the API. For sectors like collections, appointment reminders, delivery coordination, and high-value sales follow-ups, this opens a new engagement channel that sits inside the same WhatsApp thread customers already use for chat.

What this means in practice

• Businesses can potentially combine text and voice within a single customer conversation on WhatsApp.
• It is likely to carry its own consent and opt-in requirements, similar to template messaging.
• Early access and pricing details are expected to roll out through Meta's Business Solution Providers, so businesses should check with their BSP before assuming general availability.

The On-Premises API is being phased out

Meta has continued moving all businesses off the legacy On-Premises API onto the Cloud API. The On-Premises API required businesses (or their partners) to host and maintain their own servers running Meta's software; the Cloud API is hosted directly by Meta, removing that infrastructure burden. Meta has published a formal sunset notice for the On-Premises API in its developer documentation, and businesses still running on-premises deployments need to plan a migration.

Why this matters for Indian businesses

• Businesses still on the On-Premises API should confirm their migration timeline with their BSP rather than wait for a forced cutover.
• The Cloud API generally reduces server maintenance costs and simplifies scaling, since Meta manages the infrastructure.
• Migration mainly changes hosting and setup, not the core message templates or conversation-based pricing model businesses already work with.

Meta's AI agent for WhatsApp Business goes global

Meta has made its AI agent for WhatsApp Business available globally, allowing businesses to deploy Meta's own AI to handle customer conversations on the platform rather than relying solely on third-party chatbot builders. This is distinct from a business building its own bot on top of the Cloud API — it is Meta offering a first-party AI layer directly inside the Business Platform.

For Indian businesses evaluating this, the practical question is where a first-party AI agent fits alongside an existing WhatsApp Business Solution Provider setup, particularly for businesses that already have automated flows, CRM integrations, or human agent handoffs built around their current stack.

New discoverability tools for businesses and channels

Meta has also rolled out features aimed at helping people find more businesses and channels on WhatsApp, alongside additional tools for engagement and customer support discoverability. For businesses that rely on WhatsApp as a discovery surface — not just a support channel — this is relevant to how customers first find and message a business, separate from paid advertising or click-to-WhatsApp campaigns.

What Indian businesses should do now

• If you are still on the On-Premises API, start the migration conversation with your BSP now rather than waiting for a deadline.
• Evaluate the Calling API and AI agent as they become available to your account, rather than assuming immediate general availability.
• Keep template and conversation-based pricing structures in mind when budgeting for any new channel, since voice and AI features are additions to the existing platform, not replacements for its cost model.

FAQ

Is the WhatsApp Calling API available to all businesses now?

Rollout has been staged through Meta's Business Solution Providers rather than switched on for every account simultaneously, so availability depends on your BSP and account tier. Check directly with your provider for current access.

Do I have to migrate off the On-Premises API immediately?

Meta has published a formal sunset notice for the On-Premises API in its developer documentation, and businesses should treat migration as a planned project rather than an optional upgrade. Confirm the specific timeline that applies to your account with your BSP.

Is Meta's AI agent the same as a chatbot built by my WhatsApp provider?

No. Meta's AI agent is a first-party tool offered directly within the WhatsApp Business Platform, separate from any custom chatbot or automation flow your BSP or in-house team has built on top of the Cloud API.

Will these updates change WhatsApp Business API pricing?

The core conversation-based pricing model has not been replaced by these updates. New features like the Calling API may carry their own usage terms once broadly available, so businesses should confirm details with their BSP before enabling them.
