How to connect your WhatsApp Business API to YesHello account
Once you connected your Facebook Business Manager, go back to 360dialog client hub and wait for 10-15 minutes until the "Generate API key" button appears (you might need to refresh the page).
You need to copy and store your API key to your note-taking app or anywhere you preferred as long as it's safe :D
Go back to your YesHello account, and connect your WhatsApp channel (finally)! Follow the video guide below to connect your WhatsApp Business API to YesHello.
To make sure that your number is connected, you can send a test message from your personal number to your company number (the number that you connected in YesHello dashboard).
