# Streaming Audio Files

## **Streaming Audio**

**To stream audio you need to build your own URL to call our streaming service**

`https://stream.svc.7digital.net/stream/catalogue`

**You need to pass in two parameters on the call** 

| **Parameter**    | Reason                                              |
| ---------------- | --------------------------------------------------- |
| `&shopId=2020`   | To stream songs from the UMG catalog                |
| `&trackId={int}` | The 7digital trackId of the song you want to stream |

**Most importantly you need to sign each call with Oauth 1.0 headers using the consumer key and secret provided for this hackathon**

* `consumer_key = 7d4vr6cgb392`
* `consumer_secret = m4ntskavq56rddsa`

**We have created a form to help build and sign streaming URLs**

* ​[`Click here - to access Oauth signature reference​`](http://7digital.github.io/oauth-reference-page/)​
* `Do not use Postman - it does not correctly sign our URLs`

**Instructions**

1. **Enter the streaming service URL as shown**
2. **Enter your consumer\_key & consumer\_secret**
3. **Enter shopId & trackId**
4. **Click \[refresh both] button to sign API call with Oauth headers**
5. **Click URL to test stream**

## Partial Streams

**If you want to stream part of a track, you can use the range request**

**`curl -v -o partial.mp4 -H "Range:bytes=81920-" "{url to aac stream}"`**

**You will need to calculate the number of bytes that you want to start and/or finish at**
