# Requirements to get started with your own number

## **Authenticate your phone** number**.**

This can be done through a call or SMS to check if the number is working or not. Your phone number must not be associated with a WhatsApp Business Mobile App or a WhatsApp Business Account hosted by another business service provider at the time of integration.

## **Switch from WhatsApp Business App to WhatsApp API**

In case your business has an active WhatsApp account on a mobile device and you would like to use the same number for WhatsApp API, you need to delete the WhatsApp account for that number to connect with the WhatsApp API. 

#### Here's how to delete your WhatsApp Business app before applying for the API:

1. Open WhatsApp.
2. Tap [More Options](https://faq.whatsapp.com/1189188245314343/?locale=en_US\&cms_platform=android) (three dots) > **Settings** > **Account** > **Delete My Account**.
3. Enter your phone number in the [full international format](https://faq.whatsapp.com/640432094208718/?locale=en_US) and tap **DELETE MY ACCOUNT**.
4. Choose a reason for deleting your account from the dropdown menu.
5. Tap **DELETE MY ACCOUNT** to complete the process.

If you wish to retain the Business WhatsApp Number, you have to activate a New Phone Number for WhatsApp API.

## **Authenticate with your Facebook Business Account.**

This is recommended to ensure that you can use your existing Facebook Business Account for your business. If you do not have a Facebook Business Account, you can sign up for one while connecting your number.<br>

**Please note that:**

{% hint style="info" %}
You will not be able to use WhatsApp on your phone after integration, and your previous conversation history/contacts will not be migrated to BizMagnets.

If you wish to move back to WhatsApp Business or Individual WhatsApp Mobile App post integrating with BizMagnets, you will need to contact BizMagnets support.
