WhatsApp's Business Platform went through several structural changes in 2025 that directly affect how Indian businesses budget for and use the API. Meta moved from conversation-based pricing to per-message template pricing, retired the legacy On-Premises API in favour of the Cloud API, introduced a Calling API for businesses, and rolled out an AI Business Agent globally. This post walks through each change and what it practically means if you run a WhatsApp Business API account.
The pricing model changed: per-message, not per-conversation
For years, WhatsApp billed businesses on a conversation basis — a single fee covered all messages exchanged with a customer within a 24-hour window, split into categories like marketing, utility, authentication, and service. Through 2025, Meta shifted template-based messaging (marketing, utility, and authentication templates) toward per-message pricing rather than per-conversation pricing. In practical terms, businesses are now charged based on how many individual template messages they send, rather than paying one flat rate per open conversation window regardless of how many messages fit inside it.
Service conversations — free-form replies from a business within 24 hours of a customer-initiated message — remain free of charge, as they always have been. The change mainly affects businesses that send multiple template messages (for example, order updates followed by a promotional nudge) inside the same conversation window, since each message is now billed individually rather than being bundled.
The On-Premises API has been retired
Meta has been sunsetting the legacy On-Premises API, which required businesses to host and maintain their own WhatsApp Business API servers. Meta stopped supporting new setups on this legacy infrastructure and has been pushing all businesses toward the Cloud API, which Meta hosts and maintains directly. If your business or BSP (Business Solution Provider) is still running an On-Premises deployment, migration to the Cloud API is no longer optional — Meta has set firm sunset timelines and stopped issuing security or feature updates for the older infrastructure.
For most Indian businesses working through a BSP like Hyyper, this migration is handled on the provider's side and is largely invisible to the end business. If you manage your own on-premise instance directly, this is worth prioritising, since unsupported infrastructure carries both security and compliance risk.
A Calling API for businesses
Meta has opened a new front in business communication with a WhatsApp Calling API, extending the platform beyond text and template messages into business voice calling. This lets businesses initiate or receive voice calls with customers through the same WhatsApp Business Platform infrastructure they already use for messaging, rather than relying on separate telephony systems. For sectors like collections, appointment reminders, or high-value sales follow-ups, this adds a channel that was previously outside the API's scope.
An AI Business Agent, rolled out globally
Meta has also launched an AI Business Agent on WhatsApp for small businesses, made available on a global basis. The tool is aimed at businesses that don't have the resources to build a custom chatbot, offering a more automated way to handle common customer queries, catalogue browsing, and basic support directly inside WhatsApp. This sits alongside a broader set of engagement, customer support, and discoverability tools that Meta announced at its 2025 Conversations event for businesses using WhatsApp, Messenger, and Meta's business messaging tools.
What this means for Indian businesses
- Review how many template messages you send per customer conversation — per-message pricing rewards fewer, better-targeted templates over multiple message bursts.
- Confirm with your BSP whether your account is fully migrated to the Cloud API; unsupported On-Premises setups carry real risk going forward.
- Watch for Calling API access rolling out to more BSPs and regions if voice is relevant to your customer journey.
- Evaluate AI Business Agent-style tools cautiously — useful for basic query deflection, but most Indian businesses will still need a purpose-built flow for anything beyond FAQs.
Frequently asked questions
Do I have to migrate off the On-Premises API right away?
If you or your BSP are still on the On-Premises API, migration to the Cloud API should be treated as urgent — Meta has set sunset deadlines and no longer supports the legacy infrastructure with updates or fixes.
How does per-message pricing affect my monthly WhatsApp bill?
If you send multiple template messages within a single 24-hour conversation window, you'll now be billed for each message rather than one flat conversation fee. Businesses that send fewer, more consolidated templates will see less impact than those that send frequent follow-up templates.
Is the WhatsApp Calling API available to all businesses?
Access is rolling out gradually through BSPs rather than being universally available on day one. Check with your API provider on current availability for your account.
Is the AI Business Agent the same as a custom chatbot?
No. It's a more generic, Meta-provided assistant aimed at small businesses without existing automation. Businesses with specific workflows, catalogues, or compliance needs typically still benefit from a dedicated bot built on top of the API.
