An Erlang implementation for subscribing and receiving Instagram Realtime Photo Updates.

$ rebar3 release

Run in dev mode:

$ _build/default/rel/instagram_listener/bin/instagram_listener console

Remember to set in your config/sys.config all the variables needed.

Once Instagram Listener is running, you can subscribe for a given kind of update using the module client.erl inside the release shell

1> client:start_link().
2> client:subscribe(Subscription).

where Subscriptions can be: {tag, <<"yourtag">>}, {location, <<"locationId">>}, {geography, {<<"Lat">>, <<"Lng">>, <<"Radius">>}}.

You can list all your subscriptions using:

3> client:subscriptions().

You can also unsubscribe from all subscriptions using:

4> client:unsubscribe().

or you can unsubscribe from a specific object type using:

5> client:unsubscribe({object, Object}).

where Object can be <<"tag">>, <<"location">>, <<"geography">>.

or you can unsubscribe form a specific id using:

6> client:unsubscribe({id, <<"id">>).

Whenever a Realtime Update is received, the application will forward it to the module called worker.erl. It is your responsability to implement this module and make it do whatever you want (e.g. log the update, retrieve the object, etc etc).
