# unsupported_media_type

**This endpoint does not accept the Content-Type.**

| | |
|---|---|
| HTTP status | `415` |
| `code` | `unsupported_media_type` |
| Retry? | No, fix the request first |

## What it means

JSON endpoints expect `Content-Type: application/json`. Image uploads expect `image/png`, `image/jpeg`, `image/webp` or `application/octet-stream`.

## How to fix it

Set the matching header. With curl: `-H "Content-Type: application/json"` for JSON.

## Example

```json
{
  "type": "https://docs.kalender-sync.de/en/api/errors/unsupported_media_type",
  "title": "Unsupported media type",
  "status": 415,
  "code": "unsupported_media_type",
  "request_id": "req_…"
}
```
