WhatsApp Business API integration with the official Cloud API

The WhatsApp Business Platform lets software send and receive WhatsApp messages through Meta's official Cloud API. I connect it to your systems for order updates, appointment reminders, support conversations and chatbots, so messages are triggered by real events and replies land somewhere your team can act on them.

When WhatsApp Business API is a good fit

  • Order, delivery and payment notifications sent automatically from your system
  • Appointment and payment reminders that reduce no-shows and manual follow-up
  • Shared support inboxes where several staff reply from one business number
  • Guided chat flows for bookings, FAQs or lead capture, with handover to a person

When I'd suggest something else

  • Bulk promotional messaging to people who have not opted in, which breaks WhatsApp policy and risks the number being restricted
  • Very low volumes handled by one person, where the free WhatsApp Business app is simpler

How I work with WhatsApp Business API

Official API only

Integration uses Meta's Cloud API with a verified business account, not unofficial tools that risk the number being banned.

Template management

Business-initiated messages use templates submitted for Meta approval, written so they are likely to be approved and useful to the customer.

Reliable webhooks

Incoming messages and delivery statuses are received through verified webhooks, stored, and retried safely if something fails.

Opt-in and opt-out

Consent is recorded, and customers can stop messages easily, which protects both your customers and your number's quality rating.

Frequently asked questions

Is this the official WhatsApp API?

Yes. I build on Meta's official WhatsApp Cloud API, which requires a Meta Business account and a phone number registered for the platform. I can guide you through setup and business verification.

How is WhatsApp API usage priced?

Meta charges for messages based on the message category, such as marketing, utility or authentication, and the recipient's country, and its pricing model has changed over time. Customer service replies within an open conversation window are treated differently. I check Meta's current pricing for your countries before launch.

Why do message templates need approval?

WhatsApp requires messages you start, such as reminders or order updates, to use templates Meta has approved. Replies within a conversation the customer opened can be free-form. Templates usually get approved when they are clear, specific and not misleading.

Can the chatbot use AI?

Yes. Replies can be drafted or answered by a language model using your own information, with rules for when to hand the conversation to a person.
