BNex Guides
WhatsApp Business Platform, explained properly.
Straight answers to the questions that decide WhatsApp projects — which product you need, how approval actually works, what messaging costs, and how a team shares one number. Platform facts are sourced from Meta’s own documentation and dated on every page.
Comparisons
API vs Business App
The WhatsApp Business App is a free phone-based app for a single operator with no API, while the WhatsApp Business Platform (often called the WhatsApp Business API) is a paid, multi-agent, programmable service built for teams, automation and broadcast at scale.

Getting API access
Getting WhatsApp Business API access means creating a Meta Business Portfolio, verifying the business, adding a phone number that is not already on WhatsApp, and sending your first approved message template — the whole process is usually measured in days, not months.
ReadGuidance
Template approval
WhatsApp message templates are reviewed against the category you submit them in — the most common rejection is a marketing-flavoured template submitted as utility, and the fix is to describe a specific action the customer already took rather than a reason to buy.
ReadGuidance
Shared inbox setup
A WhatsApp shared inbox lets several agents answer one business number from a single view of the conversation, with internal notes and per-message read state — the hard part is not the software but agreeing who answers, who takes over, and when a conversation is finished.

Pricing explained
Since 1 July 2025 Meta charges per delivered message rather than per conversation, categorised as marketing, utility, authentication and — from 1 October 2026 — service. Every business phone number gets 1,000 free service messages a month, so most small businesses still pay nothing for replies, while high-volume automated support now carries a real per-message cost.

Why BNex
BNex is a WhatsApp Business Platform suite that combines a shared team inbox, broadcast campaigns and workflow automation in one product, built on Meta’s official Cloud API rather than an unofficial automation workaround.
ReadGuidance
Cloud API setup
Setting up the WhatsApp Cloud API means creating a Meta app, adding the WhatsApp product to it, registering a sender phone number, generating a permanent system-user token, pointing a webhook at your server, and sending your first message to an opted-in recipient — in that order.
ReadComparisons
Choosing a provider
WhatsApp Business API providers differ far less in features than in commercial model and ownership: who holds the WhatsApp Business Account, how message markup is charged, and what leaving costs. Ask about those first, because they are the parts a demo never shows.
ReadGuidance
Automation and the 24h window
A WhatsApp automation step that fires more than 24 hours after the customer’s last message cannot send a free-form reply — the customer service window has closed, so the only permitted message is a pre-approved template. This is the single most common reason a follow-up sequence that tested perfectly goes silent in production.
ReadGuidance
Keyword bots that miss
Keyword-triggered WhatsApp bots miss customers because people do not type the word the bot was built to match — they type a paraphrase, a typo, a voice note or a question. Exact-match routing works for a small set of menus and fails open on everything else, which is why the fix is usually to treat keywords as one signal rather than the only one.
ReadGuidance
Opt-outs and STOP
A customer replying STOP expects the messages to end, but WhatsApp does not enforce that for you — there is no platform-level global suppression list for business messages. Honouring an opt-out is something the business must implement, which is why automations that ignore it keep messaging people who have already said stop.
