WhatsApp Business API: Complete Setup Guide 2026
Meta approval, green tick, templates, broadcast limits and real costs — everything explained step by step.
API vs App vs Business Premium
The free App fits one phone and manual chats. The API (via providers like us) unlocks bulk broadcast, chatbots, multi-agent inbox and CRM integration on one verified number. Choose API the moment broadcasting or automation matters.
Approval and green tick
You need a Facebook Business Manager, a fresh number (never used on WhatsApp), and display-name approval. Green tick needs brand proof — website, GST, ad spend history. Most approvals complete in 3–7 days when documents are clean.
Templates, limits and costs
Promotional messages need pre-approved templates; utility messages (OTP, updates) are flexible. New numbers start at 250 conversations/day and scale to unlimited with quality ratings. Meta charges per conversation; provider fees sit on top — always ask for the full per-message math.
What to automate first
Start with abandoned-cart recovery, COD confirmation and review collection — these three flows usually pay for the whole setup. Then add catalogs, chatbots and CRM sync in phase two.
