What is a WhatsApp Business API platform?
It's software that connects your number to Meta's official WhatsApp Business API. With it several people answer the same number, you send approved templates and campaigns, automate replies and connect WhatsApp to your CRM or store.
How much does the WhatsApp API cost?
You pay two things: the platform (monthly plan) and the messages Meta charges by category and country. Since October 1, 2026 Meta also charges replies inside the 24-hour window at the utility rate. Some platforms let you pay Meta directly; others add a markup.
How do I choose a WhatsApp Business API platform?
Compare how you pay Meta's fees (direct or with a markup), how many numbers and users the cheapest plan includes, whether there's a lock-in or upfront payment and whether it includes a shared inbox, CRM and AI or only the technical connection. Always ask for the total cost.

How we made this list
The other nine are ordered by how you pay Meta's fees according to their own pages (direct to Meta or a declared 0% markup first, then their own fee, then platform credits or balance, and those that don't publish it last); within each group, by entry price.
Prices in US dollars, before tax, as shown on each provider's page; if a provider prices in another currency we say so next to the price. Meta's per-message fees are paid separately on every platform that uses the official API.
