base_url: https://firseinvoicedemo.etranzactng.com

Description:: This endpoint returns a list of standardized Unit of Measurement (UoM) codes for invoice line items. It enables the implementation of these values for the price_unit field within the schema/payload (see Validate and Sign Invoice endpoint), thereby aligning with the UN/ECE Recommendation 20 and Recommendation 21 code lists

The introduction of this resource is intended to:

• Ensure uniformity in quantity and unit representation across invoices
• Improve validation accuracy during invoice processing
• Support consistent reporting and downstream analytics

Code	Type	Name	Description
A35	String	coulomb per square millimetre	coulomb per square millimetre
A36	String	cubic centimetre per mole	cubic centimetre per mole
A37	String	cubic decimetre per mole	cubic decimetre per mole
A38	String	cubic metre per coulomb	cubic metre per coulomb
A39	String	cubic metre per kilogram	cubic metre per kilogram
A4	String	ampere per square centimetre	ampere per square centimetre
A40	String	cubic metre per mole	cubic metre per mole
A41	String	ampere per square metre	ampere per square metre
