Register an App in Entra ID

Create a service principal in Azure Entra ID that Cirrova will use to read your cost data.

Register the app

In the Azure Portal, navigate to:

Entra ID → App registrations → New registration

Give the app a recognisable name — Cirrova Cost Reader is a good choice. Leave all other settings at their defaults and click Register.

Note down two values

After registration, you'll land on the app's Overview page. Make a note of:

  • Application (client) ID
  • Directory (tenant) ID

You'll enter both of these into Cirrova in Step 5. Keep this browser tab open — you'll return to it in the next step.

Both IDs are GUIDs in the format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. They are not sensitive — only the client secret you create in the next step needs to be kept private.
