When I get a HTTP Request with: https://www.website.nl/webhooks?hub.challenge=0000
This query string consists of hub.challenge. I need to respond with the value of hub.challenge.
I can’t respond because the template-node can’t handle {{req.query.hub.challenge}}.
When I try to use hub_challenge as parameter inside the query string and change the template node it works.
But unfortunately the Facebook API works with hub.challenge to verify your server.
I want to know how to change the msg so I can change the dot to an underscore.
