What is the date format for the Healthcare Finder API? I could not locate the answer in the API Schema.
Is it "Year - Day - Month" or "Year - Month - Day"
Short answer: "Year-Month-Day", or CCYY-MM-DD
So a line like
<xs:element name="InsuranceEffectiveDate" type="xs:date"/> indicates that you should format the value according to XML Schema. This is a reference page for the date type
(the reference to
xsd:date on the linked page instead of
xs:date as specified in the API schema document is a minor style choice, and not a cause for concern.)
