TL;DR: Incomplete data between acquiring banks and issuing banks can turn legitimate ecommerce orders into false declines, and Signifyd says richer pre-authorization screening can lift authorization rates by up to 3%. The control problem is not transaction routing alone but the quality and timing of the context that reaches issuer decisioning.
NHIMG editorial — based on content published by Signifyd: Acquiring bank vs. issuing bank: merchant guide to payment flow
By the numbers:
- richer context that lets them more accurately assess risk and lift authorization rates by up to 3%.
Questions worth separating out
Q: What causes false declines in ecommerce payment flows?
A: False declines usually happen when the issuer receives too little context to distinguish a legitimate purchase from a risky one.
Q: How should merchants improve approval rates without weakening fraud controls?
A: Merchants should filter obvious fraud before authorization, then send issuers cleaner and richer transaction data.
Q: Where do banks lose visibility in an ecommerce transaction?
A: Visibility breaks where the acquirer, gateway, network, and issuer each see only part of the transaction.
Practitioner guidance
- Enrich authorization requests before submission Include billing and shipping match, device ID, behavioural patterns, and prior order history where available so issuers receive a stronger trust signal.
- Separate obvious fraud filtering from decline recovery Screen high-confidence fraud before authorization rather than relying on issuer declines to catch it.
- Review decline-code handling and remediation paths Build an internal process that maps generic decline responses to likely data-quality or trust-signal problems, then route those cases into enrichment or customer verification steps.
What's in the full article
Signifyd's full blog covers the operational detail this post intentionally leaves for the source:
- How the Authorization Rate Optimization flow uses pre-authorization screening to remove obvious fraud before issuer review.
- Which transaction fields and behavioural signals the merchant says can strengthen issuer confidence in approval decisions.
- How the post frames lower false declines and higher authorization rates as a feedback loop across merchant and issuer decisioning.
- Why the article links cleaner traffic to reduced chargebacks and better conversion outcomes.

Trust signal quality is now a core control point in payment decisioning. The article shows that authorization is not just a banking workflow, it is an information-governance problem. When merchant context is thin, issuers compensate with caution, and that caution becomes lost revenue. Practitioners should treat data completeness as a control objective, not an operational afterthought.
A question worth separating out:
Q: What should teams do when legitimate orders are repeatedly declined?
A: Teams should examine whether repeated declines are caused by poor signal quality, inconsistent transaction fields, or weak fraud enrichment before assuming the buyer is risky. A structured decline review process helps distinguish true abuse from avoidable friction and improves both authorization rates and customer experience.
