Notes
All attribute names received from NMI will be converted to camelCase
for uniformity. Attribute names sent to NMI will be converted to the appropriate hypen-case
and param_case
where appropriate. Additionally, some fields are aliased (e.g, postalCode
=> postal
) to provide consistent access between the Three Step and Query APIs.
You can disable this completely by specifying transform: false
in the configuration options.
Dispatched XML is generated by xmlbuilder.

const NMI = require('@calistyle/nmi').NMI
