Onboarding: Embedded Signup

The Embedded Signup flow is the fastest and easiest way to create a WhatsApp Business account and register a number.


To get a WhatsApp Business API Access, you will need the following: - a valid phone number - Embedded Signup entry point such as an Integration Partner. You can create a new Meta Business Account or connect to an existing one during the Embedded Signup process.

Meta Business Manager with complete Business Info

Please choose your Business Manager carefully, since it can't be changed after the number is registered.
You must add your information in the Business Info section of Business Manager Settings. You need to include a legal name, an address, a website, and the business phone number you intend to use for messaging.
Check your website
This information is used by WhatsApp team to ensure compliance with the WhatsApp Commerce Policy. If it's not completely filled, the account will be immediately blocked.
Therefore, the website must:
  • be provided
  • be working
  • be secured with SSL
  • have a clear explanation of the company's business model

Phone numbers already being used in WhatsApp App

You can use a phone number that is already registered in the Android, iPhone, or Business versions of WhatsApp. However, to register this phone number in the WhatsApp Business API, you need to follow the steps outlined on this page to delete the WhatsApp account associated with that phone number.
Once you finish deleting your app account, you can proceed with Embedded Signup. You will receive a 6-digit code via SMS or Voice call to verify the number.

Complete the Embedded Signup

It's important that this Meta account has admin access to the Meta Business Manager that will manage this WhatsApp account.
Important: do not keep the Embedded Signup pop-up open for more than 1 hour, otherwise the session will expire. Please ensure that you have all the prerequisites ready before starting.

Generate API Key or Grant Permission

When the Embedded Signup is completed, we will deploy the WhatsApp Business API Client. After deployment you will have the option to either generate an API KEY or grant your Integration Partner permission to access the number.
Generate API Key
Grant Partner Permissions pannel
To manage or grant Partner permissions, click on your profile in the bottom left → “Organization settings” → Your phone numbers will be listed and permissions can be edited.

WhatsApp Commerce Policy review

WhatsApp will review your WhatsApp Account to ensure it is compliant with the WhatsApp Commerce Policy. Be sure to examine the policy closely to make sure you are Business compliant.
This review will happen in the background, after the account is already live.
If the account is not approved on the WhatsApp Commerce Policy it will be immediately blocked. The business is able to appeal this decision by creating a support ticket. The business can also downgrade to WhatsApp Business App; you can find info regarding this process here.

Messaging and Phone Number Limits

After completing the number registration processes, the business will immediately be able to:
  • Respond to unlimited customer-initiated conversations (24-hour messaging windows)
  • Send business-initiated conversations to 250 unique customers in a rolling 24-hour period
  • Register up to two (2) phone numbers, which can both be assigned to 1 WABA or split between 2 WABAss

How to increase limits: Complete Business Verification

Businesses must initiate Business Verification when they are ready to:
  • Scale business-initiated conversations
  • Add additional phone numbers
  • Request to become an Official Business Account
And by scaling business-initiated conversations we mean using the Standard Access tier, which gives access to:
  • Currently available messaging limits (1K, 10K, 100K, unlimited unique customers/day)
  • More than 2 phone numbers
  • An Official Business Account (OBA) - Any business that requires an OBA must complete Business Verification

Display Name review

After Business Verification is finished, WhatsApp will also approve your company's Display Name.
Display Name Guidelines are very strict, and names will often get rejected for small details or minor discrepancies between the name and the Meta Business, website, or social media. To avoid this, make sure you thoroughly review Meta's guidelines.


Billing begins as soon as the WhatsApp Business API Client is deployed. This happens immediately after the successful completion of the Embedded Signup flow.
Billing start is not dependent on number registration. In certain situations, your number may not be registered when the WhatsApp Business API Client is deployed. If this happens, you must register the number manually via the 360dialog Hub.

Incorrect data

If you make a mistake with the Embedded Signup Onboarding Process such as:
- Number added to the wrong WABA - WABA added to the wrong FB Account - Account added but no Payment Method set
If you let us know within 14 days of registering the number - we will correct the mistake for you.

Possible Errors during the Embedded Signup

Throughout the Embedded Signing up you may face some errors that might interrupt the process. Here we will show you some topics you should keep in mind, especially if you are signing up for extra phone numbers beside the ones you already have.

Basic troubleshooting

You may go through this checklist:
  1. 1.
    Check Business Manager Not verified Business Managers can only have up to 2 phone numbers. So, guarantee that the correct Business Manager is ready to get the correct amount of allowed phone numbers.
  2. 2.
    Still not working Close the browser window and try it again, that might resolve the issue.
  3. 3.
    Stuck on a screen Get a screenshot of the problem you are having.
  4. 4.
    Open a ticket for our Support Team! Through the button "Create a new Ticket" on the 360 Client Hub, open a ticket explaining the issue and attach the screenshot you have. This level of detail will save the time of investigation, thus, improve the time of response.

If your account was disconnected after signup

If you went through signup and did not complete the Business Info section of the Business Manager in full, your account will be automatically disconnected after WhatsApp Commerce Policy check.
If your number was disconnected after signup, please check the Business Info section of your Business Manager. If any piece of information is missing (especially the website), you will need to fill it and then Request a Review from Meta.
You can request a review yourself from Meta Business Manager > Account Quality. You do not need to contact 360dialog to do this.
