To be able to make complete use of and maximize WhatsApp for your Business, such as Whatsapp Broadcasting and other advanced features, you must obtain the WhatsApp business platform (previously known as WhatsApp business API). For this, the primary step is to apply for the WhatsApp business platform through Wetarseel. To make the process simple, here is a comprehensive guide that ensures your application is successful and your business set for growth.

Prerequisites to Apply for WhatsApp Business API

Make sure you fulfill the below conditions before applying for WhatsApp business platform with Wetarseel:

1- A Business Website

A business website is very fundamental for getting a WhatsApp business platform. This is crucial because it proves the legitimacy of the business.

2- An Unused Phone Number

You will need a valid phone number that is not registered with any existing WhatsApp account. Alternatively, if you wish to take an old number, it must be entirely dissociated from any active WhatsApp account. If required, you need to remove the existing WhatsApp account on that number permanently.

With these prerequisites in place, you can apply for WhatsApp Business API with Wetarseel.

Want to Use WhatsApp Coexistence? Follow Step 9 Instead

Before proceeding to Step 8, decide whether you want to:

  • Use a new number only for WhatsApp Cloud API, or
  • Continue using your existing WhatsApp Business App number together with the API using WhatsApp Coexistence

If you want to keep using your existing WhatsApp Business App and API on the same number, skip Step 8 and directly go to Step 9 (Coexistence Setup).

WhatsApp Coexistence allows businesses to use both:

  • WhatsApp Business App
  • WhatsApp Cloud API

on the same phone number simultaneously. This means you can continue manual chats on the app while also using automation, CRM integration, broadcasts, and multi-agent support through the API.

This feature is officially supported by Meta and is gradually rolling out for eligible businesses.

Step 8: Create Your WhatsApp Business Profile (For Cloud API Setup) 

 Create a new WhatsApp Business Profile

You will now be prompted to create a WhatsApp Business Profile:

  • Choose a WhatsApp Business Account Name. This is not the display name, but an internal name for your WhatsApp Business account in Facebook Business Manager.
  • Set your WhatsApp Business Display Name (this is what customers will see).

Add business details

  • Select your Business Category from the available options to categorize your business (e.g., Retail, Education, Hospitality).

Step 9: Setup WhatsApp Coexistence (Use Existing WhatsApp Business App Number)

If you want to continue using your existing WhatsApp Business App number together with the WhatsApp API, choose the Coexistence option during onboarding.

This allows you to:

  • Keep your existing chats and contacts
  • Continue using the WhatsApp Business App on your phone
  • Use API automation, CRM integrations, broadcasts, and multi-agent support simultaneously
