# CredentialStackUsage

Where a credential stack is used, as defaults and by knowledge bases. While any of these use it, it can't be deleted. Runs and automations that name it aren't counted.

**Kind:** an object, used in responses.

## Fields

Every field is present in a response; empty ones are `null`.

| Field | Type | Description |
|---|---|---|
| `credentialStackId` | `uuid` | The stack's id. |
| `tenantDefault` | `boolean` | It's the tenant's default stack. |
| `namespaces` | [`CredentialStackUser`](https://docs.maitento.com/reference/types/credential-stack-user.md)`[]` | The namespaces whose default it is. |
| `partitions` | [`CredentialStackUser`](https://docs.maitento.com/reference/types/credential-stack-user.md)`[]` | The knowledge bases (partitions) that embed with it, up to 500. |
