setup whatsapp business api

Here is a complete step-by-step guide on how to setup WhatsApp business API. WhatsApp API can only be used if you follow the compliances according to the business and commerce policy of WhatsApp. In this easy and quick blogpost, I will explain the step-by-step process of setting up the API yourself and link that to Sendwo or any other WhatsApp official API-supporting application.


Prerequisite for using WhatsApp Business API

You need to have a few things beforehand in order to start using the WhatsApp API. Lets look into what you need to have in order to start your setup for WhatsApp API.

  1. You must be a registered business.

Only registered entity can be eligible for using the API. Since API setup needs to be done only over verified business manager. So, in order to verify business manager, you need to submit your business certificates.

  1. You must have a business website.

While we are verifying the business manager account of facebook, it will ask you for official website of your company. They check the terms and condition page and privacy policy page on your company website.

These pages should show the policy that is 100% in compliance with WhatsApp business policy and commerce policy. If you don’t fall into the category of allowed business, then your business manager verification will be rejected. 

  1. You must have a business phone number [Only for verification purposes]

This phone number should be your business phone number which must be also mentioned in your business document. 

When we do business verification, it ask your business documents like business registration certificates to prove that you are an official government-approved business. In that same document, Meta expects to have your business phone number also mentioned. But, in case the phone number is not mentioned, then it ask, “whether your business document contain phone number or not. If it doesn’t have that, then it ask you to upload any other government separately forwarded letter like a utility bill or bank statement that has both business name as well as your business phone number mentioned. 

With these prerequisite, you can ask your WhatsApp integration consultant to help you in getting started with setup of WhatsApp API. 

Now, lets go to step by step process

STEP 9: This is a very critical step. You must not do anything wrong in entering your info. In this step, you will add your WhatsApp Business Profile Display Name. This name should be your brand name. Business name is different, brand name is different. When you apply for a green tick, WhatsApp ask if your brand name is notable or not. They confirm this by asking you to share those website links from high authority sites that have mentioned this same WhatsApp Business Profile Display Name. It is your brand name. Enter the correct timezone because scheduled messages will go according to this time zone.

STEP 10: Enter your phone number and verify it with a security code sent to you via text message or call.

Accepted document types

The primary document types that are acceptable for business verification are as follows. Make sure these documents are not expired and are issued by the relevant authorities.

  • Certificate/Articles of Incorporation
  • Business Registration or License Document
  • Government-Issued Business Tax Document: This could include a Tax Certificate. Self-filed tax documents are not accepted.
  • Business Bank Statement
  • Utility Bill: A utility bill is accepted only for Business Address and Phone number. The Legal Business Name must be on the utility bill. A utility bill is not an acceptable document for Legal Business Name verification

If it gets rejected, you will get up to 3 chances to raise a request for re-review. If all those chances fails, you won't be able to get your business manager verified and using WhatsApp API will be impossible.
