Can you post the rest of your code for calling the API? Your parameters look fine, but how are you sending the POST?

Here is a full example for you @Ghanem Alshammari:

```auto
curl -X POST \
-H "Content-Type: application/json" \
-H "wsc-api-key: ${WSC_API_KEY}" \
-H "wsc-access-key: ${WSC_ACCESS_KEY}" \
-d '{
   "live_stream": {
     "aspect_ratio_height": 1080,
     "aspect_ratio_width": 1920,
     "billing_mode": "pay_as_you_go",
     "broadcast_location": "us_west_california",
     "closed_caption_type": "none",
     "delivery_method": "push",
     "encoder": "wowza_gocoder",
     "hosted_page": true,
     "hosted_page_sharing_icons": true,
     "name": "MyLiveStream",
     "player_responsive": true,
     "player_type": "wowza_player",
     "transcoder_type": "transcoded"
   }
}'"${WSC_HOST}/api/${WSC_VERSION}/live_streams"

```

The curl examples below use environment variables, **${WSC\_API\_KEY}, ${WSC\_ACCESS\_KEY}, ${WSC\_VERSION}, and ${WSC\_HOST}** for the Wowza Streaming Cloud API key, access key, version number, and your host.

See [Using cURL](https://www.wowza.com/docs/How-to-use-the-Wowza-Streaming-Cloud-REST-API#curl) for more information on how to set these up.

Hope this helps.
