# CredentialTestResult

What a test of a credential found: each key was used to list the provider's models at the credential's endpoint. The test passes when every key does; a passing test switches a credential its circuit breaker turned off back on.

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

## Fields

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

| Field | Type | Description |
|---|---|---|
| `credentialId` | `uuid` |  |
| `succeeded` | `boolean` |  |
| `errorCode` | `string \| null` | The first failing key's code (`CredentialErrorCodes`); null when the test passed. |
| `testedAtUtc` | `datetime` |  |
| `keys` | [`CredentialKeyTestResult`](https://docs.maitento.com/reference/types/credential-key-test-result.md)`[]` |  |
