WMS order fact integration flow with SKKO demonstrates a synchronous REST API pipeline that transforms Oracle database records into canonicalized, digitally signed JSON payloads. The process begins with a stored procedure writing initial records to MarkOut, followed by data collection, JSON formation, canonicalization, and cryptographic signing before REST transmission to the external SKKO service. Status updates track progression through sent, success, and error states, with comprehensive error logging ensuring visibility into failed transactions. Fork this diagram to customize timeout thresholds, error handling destinations, or adapt the flow for alternative external service integrations.
