How to choose a WhatsApp Business API provider in India

What does a WhatsApp API provider actually do?

Meta runs the WhatsApp Business Platform, usually called the WhatsApp Business API. A business can use Meta's Cloud API directly, but that means building its own inbox, template tools, campaign sender and automation. A provider gives you that software on top of Meta's API, and helps you connect your number. The messages still travel through Meta, so delivery rules, template approval and messaging limits are the same with every provider.

Well-known providers in India include Wati, AiSensy, Interakt and Gupshup, as well as Aethenox AI. Rather than compare feature lists, which change every month, use the questions below with each one.

1. What kind of Meta partner is the provider?

Meta works with providers as Solution Partners or Tech Providers. The difference shows up in who pays Meta. A Solution Partner can pay Meta on your behalf and bill you. With a Tech Provider, your own WhatsApp Business Account has your payment method on it, and Meta bills you directly for message fees.

Neither is better in itself. Ask which one the provider is, and then ask exactly which charges come from Meta and which from the provider, so you are not surprised by two bills. Aethenox AI is a Tech Provider; our WhatsApp Business API page explains how our wallet charges and Meta's payment method fit together.

2. Who owns the WhatsApp Business Account?

Your number, display name, templates and quality rating live in a WhatsApp Business Account. If you connect through Meta's Embedded Signup, the account sits in your own Meta business portfolio and the provider is given access to it. That makes it much easier to change providers later, because the account, and its sending history, stays yours.

3. Can you keep using the WhatsApp Business app?

Many Indian businesses already run their number on the WhatsApp Business app. Meta's coexistence option lets you connect that number to a provider and keep using the app on your phone, without losing your chats. Not every provider supports it, and Meta shows the option only for eligible numbers, so ask before you plan a migration.

4. How is pricing structured?

Most providers charge in two layers, and you should understand both:

• A platform fee: a monthly plan for the software, seats and features.
• Per-message charges: Meta prices template messages by category (marketing, utility and authentication). Ask whether the provider adds a markup, how the wallet or credit works, and whether replies to customers who message you first are charged.

Ask for prices in rupees, with GST shown separately, and for GST invoices. A low plan price with a large per-message markup can cost more than a higher plan once you send campaigns. Our own rates are on the pricing page.

5. Is the automation real AI or a menu?

Many WhatsApp chatbots are menus: press 1 for prices, 2 for timings. They break the moment a customer types a real question. Ask whether the bot can answer from your own written knowledge base, whether it can act (book a calendar slot, update a sheet or CRM, call your system through a webhook), and how it hands a chat to a person. Test it with the messy questions your customers actually send. Our AI agents vs chatbots page explains the difference.

6. Does it cover calls as well as chats?

If your customers phone as often as they message, a separate calling tool means two knowledge bases and two bills. Some providers, Aethenox AI included, offer AI voice agents that answer calls with the same agent and knowledge base used on WhatsApp. See AI voice agents.

7. What happens when you hit Meta's limits?

Meta limits how many unique customers a business can start conversations with in 24 hours, starting at 250 and rising to 2,000, 10,000, 100,000 and unlimited as you send good-quality messages. The provider cannot lift that limit, but it should show you your current limit and quality rating, and its campaign tool should tell you plainly when messages were held back or failed, not just that they were “sent”.

8. Support, API and security

• Support: hours, language, and whether you reach a person who can see your account.
• API and webhooks: so your store, CRM or app can send order updates and receive replies.
• Security: encryption in transit and at rest, role-based access for your team, and a clear answer on whether your conversations train AI models.
• Trial: a free trial on your real number tells you more than any demo.

Where to start

Shortlist two or three providers, run the same checklist on each, and try them with your own number and questions. To try Aethenox AI, start a free trial (7 days, no card needed), or read our WhatsApp Business API India guide for setup, approval and pricing in detail.
