Adobe I/O Events Authentic Delivery

Overview

Implement Adobe I/O Events registration, challenge validation, authentic delivery, idempotent enqueue, replay operations, and disablement recovery. This workflow produces a reviewable artifact and evidence before any live side effect.

Prerequisites

• Current first-party Adobe documentation for every selected service, API version, auth flow, limit, and lifecycle.
• Named product, identity, security, data, budget, release, and operations owners appropriate to the scope.
• Synthetic or approved non-production fixtures with secret and content canaries.

Current Contract

Webhook endpoints are public HTTPS and must echo the GET challenge during registration. Event delivery is at least once and may duplicate or arrive out of order. Validate recipientclientid plus the digital signature/public key from a validated static.adobeioevents.com URL, or use an approved mTLS configuration. Recheck the dated evidence map before relying on mutable product behavior.

Authentication

Use an entitled Developer Console project and least-privilege credential for registration administration. Delivery handlers never receive or log management credentials.
