How to get the WhatsApp Business API

Getting on the WhatsApp Business API takes four things: a verified Meta Business Account, an eligible phone number, a compliant display name, and a platform to connect it to. With Meta Embedded Signup the connection itself happens in a single guided flow from inside your provider's dashboard — you are not copying access tokens between browser tabs.

Before you start

Getting these right first avoids almost every rejection.

  • A phone number that is NOT currently active on WhatsApp Messenger or the WhatsApp Business app — delete the account on that number first, or use a new one
  • The number must be able to receive an SMS or voice call for verification
  • A Meta Business Account with business verification completed — have your registration documents ready
  • A display name that reflects your actual business name and follows Meta's guidelines

The steps

In order, and mostly quick.

  • Create your ConneXus account
  • Start Embedded Signup from the dashboard and sign in with Facebook
  • Select or create the Meta Business Account and WhatsApp Business Account
  • Add and verify your phone number by SMS or call
  • Set your display name and business profile
  • Complete Meta business verification if it is not already done
  • Create your first message templates and submit them for approval

How long it takes

The technical connection is minutes. Business verification is the variable — it can be same-day if your documents are in order, or take several days if Meta asks for more. Template approval is usually quick but is not guaranteed, so submit anything time-sensitive early.

Why we do not charge a setup fee

Many Indian resellers charge a one-time onboarding fee running into thousands of rupees. Embedded Signup is a self-serve flow — there is no meaningful work being done on your behalf that justifies it, so we do not charge one.

Frequently asked questions

How long does WhatsApp API approval take?

The technical connection takes minutes with Embedded Signup. Meta business verification is the variable and can range from same-day to several days depending on your documents.

Can I use my existing WhatsApp number?

Only if you first delete its WhatsApp account, and the move is one-way. Many businesses prefer a fresh number so the old one keeps working during changeover.

Do I need a registered company?

Meta business verification generally requires documentation showing the business is real. Requirements vary by entity type, so check what applies to yours before starting.
