Azure Event Grid

Azure Event Grid is a fully managed event routing service from Microsoft Azure that enables event-driven, reactive programming by ingesting events from Azure services, SaaS providers, and custom sources and delivering them to subscribers such as Azure Functions, Logic Apps, webhooks, and event hubs. It supports both Event Grid topics and the MQTT/CloudEvents-based Event Grid namespaces for IoT and pub-sub workloads. The Event Grid REST APIs and Azure SDKs use Microsoft Entra ID OAuth 2.0 bearer tokens or shared-access keys for authentication.

Azure Event Grid publishes 5 APIs on the APIs.io network, including Namespace Topics API, Publish API, Operations API, and 2 more. Tagged areas include Eventing, Event-Driven, Pub-Sub, Messaging, and Webhook.

Azure Event Grid’s developer surface includes developer portal, support, authentication, documentation, pricing, signup flow, and 9 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/azure-event-grid: open an issue to ask a question, or submit a pull request to add artifacts.
