Need help with this asap/urgent/imp/unameit

Hello everyone , i turned to reddit after not getting any answer on the internet.

I know the answer is super simple once shown

So to all the geniuses in the group , please help a brother out

THE ISSUE:

i have been trying to automate the whatsapp of my company for a while but its been hard for me

So to start off easy , i have purchased a monthly plan with whatsapp chakra and they promised they would do the things for us but it didnt happen so let it be

What our most imp requirement is to use the whatsapp chakra (saas) to send whatsapp messages to a lot of leads or follow ups

But for that we have an existing whatsapp business number but we got to convert into an whatsapp business api number , which i dont know how

The message template has been made and approved but cant be sent because of Whatsapp business Api requirement

So someone please help me out here i have more doubts but i want to clear one by one

Thank you, wes
