Network onboarding
Walmart.com via Mercury Gate is routed through MercuryGate
Stacksync maintains a certified MercuryGate connection covering 26 trading partners across 35 channels. Onboarding with Walmart on this channel reuses that connection — no separate VAN contract or certification cycle.
MercuryGate is a multimodal transportation management system used by shippers, brokers, and 3PLs; after Korber Supply Chain Software acquired it in August 2024 and rebranded in 2025, it is marketed as Infios Transportation Management. It is a TMS endpoint rather than a VAN: carriers integrate with the instance a shipper or 3PL operates. These channels carry tendering and settlement documents: load tenders out to the carrier, with tender responses, shipment statuses, and freight invoices (204, 990, 214, 210) returned.
Connecting via MercuryGate
- Enroll as a connected carrier with the shipper or 3PL that operates the MercuryGate (Infios TM) instance; onboarding is coordinated by that operator, not by a central network body.
- Agree the integration method; the platform supports EDI, REST APIs, SFTP file exchange, and webhooks.
- Map the required transaction sets to the operator's implementation guide, covering tender receipt and the response, status, and invoice documents returned.
- Run test tenders end to end with the operator and confirm status and invoice flows before production cutover.
Testing: There is no public, network-wide certification program. Testing is arranged per instance with the operating shipper or 3PL, typically as end-to-end exchange of test tenders, responses, statuses, and invoices. The platform vendor holds ISO 27001, SOC 1 Type 2, and SOC 2 Type 2 certifications, which cover the platform rather than carrier onboarding.
Timeline: No vendor-published setup timeline exists for carrier connections. Duration depends on the operating shipper or 3PL's testing schedule and the integration method chosen; connections of this kind are commonly measured in weeks.
