Recently i wondered why did not publish its api, especially because i assumed them to already use one. Therefore i created a wlan on my macbook, connected the iphone with it and sniffed some instagram traffic using wireshark. What i found is the following API. Then i started to develop a PHP-library for it at github.

[UPDATE] yesterday @mislav contacted me and linked me his api-documentation which is much nicer than mine 🙂 here you go:

The base for all urls is – “v1” lets us expect, that they currently develop v2 which will probably be released some time. Normally uses gzip as enc-type for communication.

The following list is not complete. You may guess other actions from the url-names, i only tested a few and only some of them made it into my PHP-library.

“pk” stands for primary key i suppose.

Action URL Parameters response
login accounts/login/ username, password, device_id {“status”:”ok”}{“status”:”failed”, “message”:”some error message”}
user details users/[pk]/info/ {“status”: “ok”, “user”: {“username”: “xxx”, “media_count”: 0, “following_count”: 0, “profile_pic_url”: “http://xxx.jpg”, “full_name”: “xxx”, “follower_count”: 0, “pk”: pk}}
post comment media/[pk]/comment comment_text {“comment”: {“media_id”: pk, “text”: “xxx”, “created_at”: 0, “user”: {“username”: “xxx”, “pk”: pk, “profile_pic_url”: “http://xxx.jpg”, “full_name”: “xxx”}, “content_type”: “comment”, “type”:1}
change media data media/configure device_timestamp=0&caption=xxx&location={“name”:”xxx”,”lng”:0,”lat”:0,”external_id”:0, “address”:”xxx”,”external_source”:”foursquare”} &source_type=0&filter_type=15 {“status”: “ok”, “media”: {“image_versions”: [{“url”: “xxx.jpg”, “width”: 150, “type”: 5, “height”: 150}, {“url”: “xxx.jpg”, “width”: 306, “type”: 6, “height”: 306}, {“url”: “http://xxx.jpg”, “width”: 612, “type”: 7, “height”: 612}], “code”: “xxx”, “likers”: [], “taken_at”: 0, “location”: {“external_source”: “foursquare”, “name”: “xxx”, “address”: “xxx”, “lat”: 0, “pk”: pk, “lng”: 0, “external_id”: 0}, “filter_type”: “15”, “device_timestamp”: 0, “user”: {“username”: “xxx”, “pk”: pk, “profile_pic_url”: “http://xx.jpg”, “full_name”: “xxx”}, “media_type”: 1, “lat”: 0, “pk”: 0, “lng”: 0, “comments”: [{“media_id”: 0, “text”: “xxx”, “created_at”: 0, “user”: {“username”: “xxx”, “pk”: pk, “profile_pic_url”: “http://xxx.jpg”, “full_name”: “xxx”}, “content_type”: “comment”, “type”: 1}]}}
like media media/[pk]/like/ {“status”: “ok”}
upload media media/upload (multipart/form-data) device_timestamp=0 lat=0 lng=0 photo=(binary data)filename=”file” {“status”: “ok”}
show friend details friendships/show/[pk] {“following”: true, “status”: “ok”, “incoming_request”: false, “followed_by”: true, “outgoing_request”: false}
show own feed feed/timeline/? (the last ? may be a number that defines how many elements you want to load, but i haven’t tested it so far) what you get back is very massive (and would be a repetition), therefore only an overview:

{“status”:”ok”, “items”:[— a list of media-items (similar tothe response to changing a media —],”num_results”:0}

show feed of a user feed/user/? (same as above) (same as above)

As i already said, there are definitely more actions that are possible. But i didn’t try everyone. I’m happy with reading from, what is what i did at ma instagram.

I hope i can bring this api into a nice form to read in the near future.

Hope that helps someone.
