# Test recipient source unavailable

The KeenAuth APIs return this problem type with HTTP status 503 (Service Unavailable).

## Problem type

| Field | Value |
|---|---|
| Type URI | `https://docs.keenauth.com/errors/test_recipient_source_unavailable` |
| Code | `test_recipient_source_unavailable` |
| HTTP status | 503 Service Unavailable |
| Title | Test recipient source unavailable |

## Meaning

Whether the test recipient is allowed cannot be checked right now, so the send stays blocked (fail closed).

## Example response

Example response body. `detail` is a human-readable English description that is not meant for end users; `instance` identifies the request.

```json
