Enrich Order Batch with VAT for Fulfilment API
Nexova's order management flow forwards confirmed orders to an external Fulfilment API before dispatch. The API rejects any payload that contains non-confirmed orders or is missing the computed gross amount. In this challenge you will filter an incoming order batch down to confirmed records only, then enrich each one with a VAT rate pulled from a pre-loaded configuration variable and a computed totalGross field ready for the downstream API.
