How to get the WhatsApp Business API and connect your number

6 min read

The WhatsApp Business API is what lets software send and receive WhatsApp messages for your business. EntecLeadAI walks you through applying and connecting, even on the Free plan.

  1. Create a free EntecLeadAI account

    Sign up, then open WhatsApp → Number & settings from the menu.

  2. Start the Meta signup

    Choose the Meta signup option. A Meta window opens: pick or create your Meta Business portfolio and your WhatsApp Business account.

  3. Add and verify your phone number

    Enter the number you want customers to message. Meta sends a code by SMS or call; type it in. The number must not be in use on the WhatsApp app at the same time.

  4. Finish and come back

    When Meta closes the window, EntecLeadAI shows your connected number, its quality rating and messaging limit.

  5. Send a test message

    On the same page, type your own mobile number and press "Send test". WhatsApp's "Hello World" message arrives in seconds — your connection works.

Tip: Meta approves display names separately; until then your number shows as the phone number to customers.
