Whatsapp Business API Integration NodeJs

Whatsapp Business API Integration Node.js could have been an exhaustive process for any developer as per the latest norms you cannot begin the development process and designing the message template till you have verified business account for Facebook first and hence, Whatsapp account and the entire verification process could take from 2 days to 14 days. And to wait for 14 days to even start with the development for developers who are billed for hours of labor is not feasible. Because of this limitation, there are few third-party software that has let developers use the sandbox model in the development mode and begin the process without setting us an official business account manager. Blessing right! Here, we are using one of the many third parties available namely Twilio. Install the npm module package, and then start using the sandbox model straightaway. Though it has limitations as you can only test with one phone number which you have registered and very few messages before you verify the business account officially. But still, that’s the best and only thing available. So, let’s start with the tutorial.

1.Install npm module
