PSD2's Strong Customer Authentication mandate has evolved dramatically entering 2026, and API keys are no longer passive credentials — they must actively participate in multi-factor authentication chains to satisfy regulators across the EU and beyond. Understanding how your integration handles SCA exemptions, dynamic linking, and token-level attestation can mean the difference between seamless payment flows and costly transaction declines. In this deep dive, we break down exactly what SCA compliance looks like at the API layer, and how wabbark's key management infrastructure keeps your integrations audit-ready at every step.
