I’ve been playing around with Spark’s webhooks and successfully set up a hook and response on a local server.
I then tried to set up an application on Heroku which responds to the webhook and triggers a push notification, but with no luck. If I visit the Heroku app via my browser, it works as it should (push notif is received). It therefore seems to be a challenge with the headers sent by the Spark webhook (or lack hereof), though I’m not a 100% sure about this.
Therefore I wanted to hear if anyone has experience with Spark’s webhooks and Heroku, and/or other services like Heroku that work using webhooks.
