Embedded Signup is being updated with a new Phone Number First flow. You can preview it by enabling v3-public-preview. In this flow, business customers enter and verify their phone number at the start of signup, before they create or select business assets. This surfaces phone number eligibility and verification issues earlier.
Functionality between v3-public-preview and v3 is identical. The key differences are the simplified UI and the Phone Number First flow.
Enterprise number flow
Authentication screen
This screen authenticates business customers using their Facebook or Meta Business Suite credentials.
This screen describes the data the business customer will be permitting your app to access.
Phone number entry screen
This screen lets the business customer enter a new business phone number, or select an existing phone number from the dropdown, to associate with their WhatsApp Business Account. In v3-public-preview, the phone number is the first piece of information collected, before any asset selection.
Phone number verification screen
This screen lets the business customer verify ownership of the phone number entered in the previous step. The customer can choose to receive the verification code via SMS or voice call from this screen, then submit the code to complete verification.
If you are providing phone numbers to your customers, you will have to deliver these codes, or provide pre-verified numbers instead.
Business asset selection screen
This screen lets the business customer select existing business assets, such as a Meta business portfolio and WhatsApp Business Account, to use with the new phone number.
Customers can also create new assets if they have not reached their portfolio limit.
New business creation screen
This screen lets the business customer create a new business portfolio or WhatsApp Business Account if no suitable existing asset is available.

This screen indicates that all of the business customer’s assets (business portfolio, WhatsApp Business Account, phone number display profile, and business phone number) were successfully created and associated.
When the customer clicks Finish, a message event is triggered containing the customer’s WhatsApp Business Account ID and business phone number ID, which you must use to onboard the customer to the platform.
Coexistence flow
The Coexistence flow is automatically triggered when the business customer enters a phone number that is already in use with the WhatsApp Business app. Coexistence lets the business keep using the app on their phone while also enabling Cloud API access on the same number.
