+1I am trying to setup a webhook subscription and am getting an error “GET to callback URL does not return 200”.
My callback URL is:
Which does in fact give a 200 OK response (see images 2 and 3, response and headers).
Why is the /push_subscriptions POST throwing back an error that the callback URL “GET to callback URL does not return 200”?
+3I just went through this and it ended up being that my SSL Certificate on my host domain was incomplete. Not sure if that applies to your situation though!
+3So originally I thought mine was fine too, but it was missing one of the certificates, so it was incomplete. I didn’t notice until I ran an SSL check on my server.
+1Seems to be totally green :)
