General Developer Guidelines

Authentication

All API calls must be authenticated, please see the document Issuing Requests for more details.

Rate Limiting

REST API requests are subject to rate limits. Any applicable rate limits for a given REST resource endpoint are listed on its documentation page. Please also refer to the Rate Limiting documentation for more general information.

Date Format

By default, all dates are expected in the format of YYYY-MM-DD (for example, 1996-07-23).

If you would like to set a custom date format you must provide a formatting string along with the data. This is indicated by prefixing the field name with a percent sign (%) like so:

curl -d "BIRTH_DATE=July 23, 96" -d "%BIRTH_DATE=MMMM d, yy" … $VERIFICATION_URL

The formatting string follows the conventions of java.text.SimpleDateFormat

Error Codes and Conditions

API responses come primarily through HTTP status codes, though sometimes there is additional information in the response. Below are the error codes you can expect to receive and their general meanings. Individual REST endpoints may also have more specific documentation about expected error conditions. For an overview of how HTTP status codes are used to relay errors (with some examples), see our REST HTTP Errors documentation.
