A nodeJS port for the undocumented snapchat HTTP API. So far only login is implemented (which gives you all followers and snaps). You can post to any endpoint of the snapchat API though but you have to handle the response yourself. Feel free to enhance, fix and use it as you like! This is an early development stage.

Undocumented Snapchat API ported in nodeJS

Important: This is an early development stage. So far only login is implemented. You can however post to any endpoints of the API but you have to deal with the response yourself

Usage

Login

Provide a username and a password. The response of snapchat will contain the friends, the besties, the snaps and some additional information.

helpers.login(USERNAME, PASSWORD, function(res) { someCallback(); }, function(err) { someError(); });

Post to any API endpoint

The first and second hashparam are most likely helpers.static_token and helpers.nanotime(). To give maximum flexibility though, I implemented this in a configurable way:

helpers.postToSnapchatApi('/myEndPoint',{my: data}, [hashparam1, hashparam2], function(res) { someCallback(); }, function(err) { someError(); });

That's it so far. Feel free to enhance the script and remove any errors or inconsistencies.
