One-Click API Onboarding

Seamlessly Connect to the WhatsApp Business API

Getting started with the official WhatsApp Business API used to be a technical nightmare. WACM.in's Embedded Signup flow eliminates all complexity with a single click that handles everything automatically.

Keep Your Existing Number: No need to get a new number. Our parallel mode lets you use your existing WhatsApp Business number alongside the API - your current conversations continue while you gain API powers. No downtime, no number change, no disruption.

The Facebook embedded UI handles authentication, token exchange, WABA discovery, phone registration, and webhook subscription automatically. What used to take days of technical back-and-forth now completes in under 60 seconds.

The Onboarding Process:

  1. Click Connect: Initiate embedded signup from your WACM dashboard.
  2. Facebook Login: Authenticate with your Facebook Business account.
  3. WABA Discovery: 5-layer fallback strategy automatically detects your WhatsApp Business Account.
  4. Phone Selection: Choose the number to connect (existing or new).
  5. Auto-Configuration: Tokens, webhooks, and subscriptions configured automatically.
