WhatsApp Business API integration
The channel your customers already read — connected to the system that knows what to tell them.
Messaging
Chosen per project
Maintainable handover
In this market WhatsApp is where customers actually respond. Email goes unread and SMS is treated as spam, while a WhatsApp order update is opened within minutes. That makes it the highest-value integration for many businesses here.
It is also a channel with rules. Business-initiated messages must use templates approved in advance, and free-form replies are only permitted inside a window after the customer writes. Building around those constraints from the start avoids a number rated poorly or blocked.
What we build with WhatsApp API
Order confirmations, dispatch and delivery updates
Payment reminders and appointment confirmations
Support conversations routed into a shared inbox
Field staff receiving job assignments and sending back proof of work
Where it fits — and where it does not
Good fit when
Transactional updates customers genuinely want
Businesses already handling enquiries on WhatsApp informally
Two-way conversations that need to land in a system, not a personal phone
Consider something else when
Bulk marketing, which risks quality rating and blocking
Anything sent without opt-in
What you can send, and when
The constraint that shapes every WhatsApp integration.
Opt-in captured
Consent recorded with source and time.
Template message
Business-initiated contact uses approved templates.
Customer replies
A free-form service window opens.
Window closes
Back to templates until they write again.
How we work with WhatsApp API
Templates designed for approval
Message templates written to meet Meta’s policy first time, and versioned in the repository.
Consent recorded
Opt-in captured and stored with a timestamp and source, so it is provable.
Delivery status tracked
Webhooks recording sent, delivered, read and failed, so nobody assumes a message arrived.
Fallbacks
SMS or email when a WhatsApp message cannot be delivered, rather than silence.

Frequently asked questions
Marketing templates exist and are permitted with opt-in, but heavy promotional sending damages your quality rating and can get the number restricted. Transactional messages are where the reliable value is.
Meta charges per conversation, with rates varying by category and country. We would model the expected volume so the running cost is known before you commit.
Yes — that is the point of the integration. Messages are triggered by events already happening in your ERP, CRM or order system rather than typed by a person.
