- ec_level (optional): a string indicating which error correction level to use:
- "L": recoverable up to 7%
- "M": recoverable up to 15%
- "Q": recoverable up to 25%
- "H": recoverable up to 30%
Sample body payloads:
{
"data": "String",
"ec_level": "H"
}{
"data": [98,121,116,101,115],
"ec_level": "L"
