The Instagram Real-Time API POST updates my subscribed node server twice for each 'tag' event. What can I do on my server side and/or in my Instagram API settings to receive only one notification per subscribed event?
(This problem has been raised on SO, but the respondent did not describe their steps clearly enough for me to apply in my case.)
Per the Instagram real-time API docs, a response to the POST is required (within 2 secs) and my server omitted a response!
