I just found a way to download snapcodes with or without the Bitmoji on them and thought it was really cool. Also, since SnapChat does not have an API, I found this to be even cooler because the method I used to get the snapcodes could be used in an unofficial SnapChat API in the future.
git clone https://github.com/sdushantha/SnapCode.git
usage: snapcode.py [-h] [-b] [-s SIZE] username
A simple command-line tool to download SnapChat codes.
positional arguments:
username
optional arguments:
-h, --help show this help message and exit
-b, --bitmoji SnapCode with Bitmoji
-s SIZE, --size SIZE Size of the SnapCode (pixels)
The -b command lets you choose if you want Bitmoji on the SnapCode.
The file will download to the directory where you ran snapcode.py from.
