Parameter	Required or Optional	Description
cht=qr	Required	Specifies a QR code.
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.
chd	NOT USED	QR codes are unusual in that the chd parameter is ignored. Don't include it in your URL.
choe=<output_encoding>	Optional	How to encode the data in the chart. Here are the available values: UTF-8 [Default] Shift_JIS ISO-8859-1
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. See the appendixfor details. 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 chart. This is in rows, not in pixels. (See below to learn what rows are in a QR code.) The default value is 4.
