# Producer Upload Reference Audio API Integration Instructions

> Producer Music Generation 集成指南 - XHuoAPI

Producer allows us to upload reference audio for secondary creation. This document explains the integration method of the related API.

This API has only one input parameter, which is `audio_url`, a publicly accessible CDN address that supports the mp3 suffix.

The `audio_url` we input is `https://cdn.xhuoapi.ai/suno_demo.mp3`, which is a publicly accessible CDN address.

```bash theme={null}
curl -X POST 'https://api.xhuoapi.ai/v1/producer/upload' \
-H 'accept: application/json' \
-H 'authorization: Bearer {token}' \
-H 'content-type: application/json' \
-d '{
  "audio_url": "https://cdn.xhuoapi.ai/suno_demo.mp3"
}'
```

The result is as follows:

```
{
  "success": true,
  "task_id": "23e7d4ec-d1a8-429f-87d8-9f53fc3b6666",
  "data": {
    "audio_id": "d906da31-87cb-42f5-98df-2fc4969923b1",
    "lyric": "[Mandopop, Acoustic Pop]\n[Soft female vocals, bright and cheerful]\n\n[Verse 1]\nThe sunlight shines on the beach\nThe waves laugh brightly\nYou and I on the sand\nThe clock stops ticking\nThe ice cream is melting\nHand in hand for a walk\nThe wind gently blows\nThe heartbeat keeps beating\n\n[Chorus]\nSummer summer\nTime stops on this day\nLaughter echoes\nThe blue sky is beside us",
    "audio_url": "https://storage.googleapis.com/corpusant-app-public/producer/raw/d906da31-87cb-42f5-98df-2fc4969923b1.mp3"
  }
}
```

As can be seen, the `audio_id` field in `data` is the song ID after uploading.

With the song ID, we can use the [Producer Audios Generation API](https://api.xhuoapi.ai/documents/producer-audios-integration) to generate custom songs. For example, by passing `action` as `upload_extend` and `audio_id` as the returned song ID, we can generate a new song based on the reference audio.
