Syntax

Root URL: http://getqr.herokuapp.com/qr

Parameter	Required or Optional	Description
chs=<width>x<height>	Required	Image size.
chl=<data>	Required	The data to encode. Data can be digits (0-9), alphanumeric characters, binary bytes of data, or Kanji. You cannot mix data types within a QR code. The data must be UTF-8 URL-encoded. Note that URLs have a 2K maximum length, so if you want to encode more than 2K bytes (minus the other URL characters), you will have to send your data using POST.
chld=<error_correction_level>|<margin>	Optional	error_correction_level - QR codes support four levels of error correction to enable recovery of missing, misread, or obscured data. Greater redundancy is achieved at the cost of being able to store less data. Here are the supported values: L - [Default] Allows recovery of up to 7% data loss M - Allows recovery of up to 15% data loss Q - Allows recovery of up to 25% data loss H - Allows recovery of up to 30% data loss margin - The width of the white border around the data portion of the code. This is in rows, not in pixels. The default value is 4.

Example
