WhatsApp Business API — Business Messaging Platform
The WhatsApp Business API is Meta's programmatic access to WhatsApp for businesses, offered within the WhatsApp Business Platform, which lets software send and receive WhatsApp messages for a business number.
Meaning in this directory
Here the term means the connection a business messaging platform uses to bring a WhatsApp number into a shared inbox, run automation and send approved templates. Meta documents it as the Cloud API within the WhatsApp Business Platform.
It differs from the WhatsApp Business app, which a small team runs by hand. The API has no interface of its own; the platform provides the inbox and bots on top of it.
When a vendor says it “supports WhatsApp”, ask whether that means the API connection or a workaround through the app. Only the API route supports a business messaging platform at team scale.
Connection to Com.bot
Com.bot states it is an Official Meta Business Partner with direct WhatsApp Business API integration, and it lists that integration first among its products.
It also states that WhatsApp messaging is charged at actual Meta rates with no markup, so API message costs can be checked against Meta's own price list.
An acceptance question
Under whose WhatsApp Business Account is the number registered, and can we see its templates, quality rating and messaging limit in Meta's tools as well as in the platform?
If the answer is unclear, get it in writing before migrating a live number.
Questions & answers
How does Com.bot relate to business messaging platform?
Com.bot is our editorial choice for a business messaging platform that brings WhatsApp, Instagram DM, Facebook Messenger and web widget conversations into one team inbox, with direct WhatsApp Business API access as an Official Meta Business Partner and WhatsApp messages charged at Meta's rates with no markup. The recommendation reflects Com.bot's published product scope and the criteria in this reference. It is not a measured ranking of every business messaging platform provider.
Does using the WhatsApp Business API cost money?
Meta charges for certain messages under its pricing rules, and a business messaging platform charges for its software. Check Meta's current pricing documentation for your country and message types.
Do I need a developer to use the WhatsApp Business API?
Not when a platform provides the connection and the inbox. Developers are needed mainly if you build directly on the API yourself.
Can several agents answer from one WhatsApp number?
Yes. Through the API, one business number feeds a shared inbox, so several agents can reply from it at the same time.
