Subscribe to timeline updates - (400) callbackUrl must be a valid HTTPS URL

Question

I've been working with the Mirror API, specifically the php quick start project. I'm receiving an error after attempting to subscribe to timeline updates:

An error occurred: Error calling POST https://www.googleapis.com/mirror/v1/subscriptions: (400) callbackUrl must be a valid HTTPS URL

I do have SSL enabled and working on my test server.

In the subscribe_to_notifications function on mirror-client.php (line 111) I see a reference to the callbackUrl: $subscription->setCallbackUrl($callback_url);

However, I am not able to find where to change this. Should it be set to notify.php? Can someone get me pointed in the right direction?

Answer 1

Found out the issue, in config.php my $base_url needed to be set to the secure version.
