Meta's Cloud API lets your system send WhatsApp messages from approved templates, hold two-way conversations, add tap-to-reply buttons and receive incoming messages. A custom integration sends the right message when something happens in your system, and acts on the customer's reply straight away. See the WhatsApp Business API guide and setting up the API in the UK.
Every WhatsApp integration involves Meta's approvals, templates, the 24-hour reply window and webhooks, and none of that comes off the shelf. Resellers wrap all of this in a monthly fee on top of Meta's charges. Building directly on Meta's Cloud API means you only pay Meta.
Not included: your Meta business account and verification documents, Meta's messaging charges, a phone number not already on WhatsApp, and CRM or helpdesk integration below the support automation tier.
Payment is 50% to start and the balance on completion. For more on costs, read what the WhatsApp Business API costs.
Send a short written spec by WhatsApp, text, email or the form: which messages you want to send, what triggers them and whether customers need to reply. I'll reply within 24 hours with a quote.
Yes. The app is for handling chats by hand, one at a time. The API sends messages automatically from your system and handles replies without anyone opening an app.
Messages you start must use templates Meta has approved. Once a customer messages you, you can reply freely for 24 hours. I write and submit the templates as part of the build.
Usually 1–3 weeks from starting Meta verification to the first live message. Meta's business verification takes a few working days, and templates are often approved within hours. The build carries on in test mode meanwhile.
Meta charges you directly for template messages, at rates that depend on the message type and country, and it changes them from time to time. I'll point you to their current UK rates when we start. The build price covers the integration only.
Not at the same time. A number on the WhatsApp app has to be moved over before the API can use it, so most businesses use a separate number for the API.
WhatsApp gets more attention and supports buttons and images. SMS reaches everyone and is simpler to set up. Many businesses send WhatsApp to customers who use it and SMS to everyone else.
