KeyBank Webhooks
The KeyBank Webhooks service delivers real-time payment event notifications to subscribed commercial client applications for ACH, Wire, and RTP alerts. It defines client-hosted callback endpoints (alert codes such as AL00901, AL00906, and AL00907) that KeyBank invokes to push status and settlement events, allowing consuming systems to react to payment lifecycle changes without polling the inquiry APIs. Callback delivery follows the same OAuth2 and certificate-based security posture as the rest of the KeyBank API catalog.
