Verification of the company to connect WhatsApp Business API. Step-by-step analysis
To access the WhatsApp Business API, you need to pass verification in Meta Business Manager. Verification is the process of confirming a number of Important Meta requirements. For example: compliance with the principles of WhatsApp policy, confirmation of the address, organization name and number.
Presumably from September 2021, the need for business verification to access the WhatsApp Business API will be canceled or simplified, but verification will remain an integral element for providing broader functionality to the WhatsApp Business API, as well as for the status of an official Business Account.

Let's consider the verification process step by step
Stage 1. Registration in Meta Business Manager.
To get started, register on the Facebook Business Manager website . If you are already registered, then just select your company and go to stage 2, if not, then create an account. To create a Business Manager account, you will need a Facebook profile.

2-Click create an account;
3-Enter the company name, your name and work email address, and then click "next";
4-Add information about your company and click "submit". Enter the truthful information that you will be able to confirm in the future. Facebook is very sensitive about the reliability of data and can block your account if it notices something suspicious.
Stage 2. Verification in Meta Business Manager

Company Confirmation
In the "Security Center», pay attention to the item "Business Verification Status". If the button is active for you, click on it and proceed to uploading the authentication documents. If not, follow the instructions below.
