The WhatsApp Business API is the programmatic side of the WhatsApp Business Platform. A system sends approved template messages and receives customer messages through a provider the customer contracts. Novatelia’s published work is that integration. Novatelia is not a Meta business-solution provider, is not an official WhatsApp provider, and does not publish a price per message.

Key points
- The customer holds the business account.
- Outbound business-initiated messages use templates.
- A webhook is how the customer’s system hears about a message.
Definition
It is an interface and a set of platform rules, not a handset application. Session messages and template messages follow the platform’s current categories and windows.
How it works
The provider connects the customer’s number to the platform. The customer’s application calls the provider or the platform to send a template, and it exposes a webhook for inbound events. Failures and opt-outs are part of the application, not an afterthought.
Architecture
- Business account, number, and provider contract.
- Templates for each outbound purpose.
- The customer’s application, webhook, and the CRM or portal it updates.
Use cases
- Shipping or appointment notices leave an application.
- A support desk should see WhatsApp beside other cases.
- A one-time password might use SMS instead, which is a different solution.
Selection guidance
- Confirm the customer can hold the account and contract the provider.
- Separate utility notices from marketing messages.
- Keep general API work on the API-integration solution when WhatsApp is only one of several systems.
Questions
Is there a Novatelia WhatsApp number for customers to buy?
No. The page is an integration scope. Numbers, accounts, and provider contracts belong to the customer. No message price is listed.
What is a webhook in this context?
An address on the customer’s system that the platform or provider calls when a message arrives. The WhatsApp solution describes that path. It is not a general definition of every API.
