Support for configuring KQL Data Connection via API in Fabric Eventstream

Hi all,

I would like to submit a feature request regarding the Microsoft Fabric Eventstream REST API.

Currently, it is possible to programmatically:

• Create an Eventstream

• Update its definition

• Configure an Eventhouse destination (including database and table mapping)

However, there is a missing step that cannot be performed via API:

After publishing the Eventstream topology, the final step "Configure KQL Data Connection" (available in the UI) is required to fully enable ingestion into the Eventhouse table.

At the moment:

• This step is only available through the UI

• There is no documented or supported API to complete this configuration

• This creates a blocker for full automation and CI/CD scenarios

For teams working with Infrastructure as Code and automated deployments, the inability to configure the KQL Data Connection programmatically means:

• Eventstream deployments cannot be fully automated

• Manual intervention is required after each deployment

• CI/CD pipelines are incomplete

Requested enhancement

Provide an official and supported way to:

• Configure KQL Data Connection via REST API

• Or include this configuration within the Eventstream definition payload

This could be implemented as:

• A new API endpoint for managing Eventhouse ingestion connections
  or

• Extending the Eventstream definition schema to include this configuration

This capability would significantly improve automation scenarios and align Eventstream with other Fabric resources that already support full API-based deployment.

Thanks for considering this request.
