How to Apply for WhatsApp Business API

Are There Any Restrictions for Certain Companies?

Before applying for the WhatsApp Business API, there are three main requirements in addition to your business registration:

1. A Business Website with Complete Details
Your website should clearly display your business's legal name, preferably in the footer. This ensures Facebook can verify your business identity during the API approval process.

2. A Fresh Phone Number
The number you plan to use for WhatsApp Business API must not be currently registered on any WhatsApp app. A “fresh number” is required to avoid conflicts with existing WhatsApp accounts.

3. Official Business Documentation
You will need a valid legal document for your business, such as a GST certificate, MSME registration, or incorporation certificate, to verify your organisation.

To get started, you need to fill out the official WhatsApp Business API application form on behalf of your company. The form requires basic business details and some specific entries related to your API setup.
