Hey my bros. I’m trying to create a simple messenger bot just for fun using this tutorial:
https://medium.com/crowdbotics/...
But it seems that I’m kinda stuck with setting up the webhook on the fb page, it displays an error
“the url couldn’t be validated, callback verification failed...”
I googled for answers but it seems that it doesn’t work for me. Can you please help me? Thank you so much.
