Supported Zip Code Formats
When submitting a customer via the POST /participants/customers/new endpoint, the Zero Hash API has the following validation logic on the zip field:
- Can either be 5 numbers (standard format) or 5 numbers, a hyphen, followed by 4 more numbers (Zip+4).
- Standard:
12345 - Zip+4:
12345-6789
- Standard:
- Avoid trailing whitespace, i.e. you should submit
"12345"and not"12345 ".
