How It Helps

Build Event Grid custom topic configs with CloudEvents schema, event subscriptions, advanced filters, and dead-letter destinations. This tool helps Azure engineers generate valid configurations quickly without consulting documentation, reducing errors and accelerating infrastructure deployment. All processing runs in your browser with no data sent to external servers.

Things Engineers Ask

Does this Event Grid Topic builder consider the RBAC role needed to apply the configuration?

No — generating a Event Grid Topic configuration is independent of the role required to apply it. Apply the output with a principal that has the documented permissions for that service. For least-privilege scoping, Azure's built-in roles and the Privileged Identity Management 'just enough access' workflows give you a starting point.

How does this Event Grid Topic builder keep up with new Azure features?

The Event Grid Topic options surface what is currently documented in the Azure reference for that service. When Microsoft adds a new property or value, we add it here after verifying the schema in a real subscription. If a recently-announced feature is not yet selectable, treat that as a 'not yet supported' signal rather than an opinion that it should not be used.

Practical Applications

1Producing a Event Grid Topic starting point for a new service that follows the Azure reference architecture rather than copy-paste from another team's repo.
2Translating an Azure architect's whiteboard sketch into a concrete Event Grid Topic spec engineers can apply.
3Onboarding a new engineer by giving them a Event Grid Topic sandbox to iterate on without touching live subscriptions.
4Sketching a Event Grid Topic migration from one Azure subscription to another with subscription and resource-group differences called out.
