Details

Inputs can be passed as either string or numeric. Inputs will be padded will leading zeroes. They will be padded to the minimum length of that field. For example, the ZIP code will be padded to a minimum of 5 digits. If an input has greater than the minimum number of digits and leading zeroes, the input should be provided as a string containing the leading zeroes.

For example, if there is a 9-digit ZIP code 012345678, it should be provided as a string containing the leading zero.
