Introduction
In a world where event-driven architectures (EDA) are gaining traction, enterprises need a central and consistent way to document, discover, and consume events. SAP is addressing this need with an exciting roadmap initiative: enabling the SAP Developer Hub to act as a central Event Catalog.
This blog will walk you through the motivation behind this feature, how it fits into SAP’s broader strategy, and what steps you can take to prepare. We'll also include some insights into the current capabilities and what’s coming next.
Why a Central Event Catalog Matters
Managing asynchronous APIs and events across hybrid landscapes can quickly become complex. Having a unified developer experience—where both REST APIs and events are discoverable in one place—simplifies onboarding and integration across teams.
This aligns perfectly with SAP’s vision for a unified API consumption layer, with the SAP Developer Hub playing a central role.
Roadmap Highlights
SAP has identified several key innovations in this space, as published in the SAP Roadmap Explorer. Here are some of the most relevant items:
✅Developer Hub: Event Catalog - Basic Discovery
SAP has enabled basic discovery of events directly via the Developer Hub. This allows developers to search, browse, and inspect event metadata just like they would with REST APIs.
✅ Expose Event Definitions via API Business Hub
This has enabled event definitions available in a reusable and standardized format, ensuring that producers and consumers can align on payload structures, topics, and semantics.
🔜Enhanced Event Metadata
SAP plans to enhance event metadata support, offering more insights into event types, versions, and schemas. This will enrich the Event Catalog experience and further empower developers working in event-driven scenarios.
How does it look like: Event Catalog in Developer Hub
Let's do it based on one example Event from SAP Integration Suite, advanced event mesh to Developer Hub.
Download AsyncAPI
In SAP Integration Suite, advanced event mesh navigate to Designer > API Product > Event > Download AsyncAPI
Create Event Product
In SAP Developer Hub navigate to Admin Center > Content > Products > Add Event > Publish
Discovery SAP Events from SAP Integration Suite, advanced event mesh in Developer Hub
In SAP Developer search/navigate to your Event
Conclusion
The introduction of an Event Catalog in the Developer Hub is a major step forward in enabling event-driven, loosely coupled architectures in the SAP ecosystem.
If you're working with events today—or plan to—this is the right time to explore the feature, start aligning your assets, and get ready to expose your events to the wider enterprise.
