We are using AES Clear Key Protection for our assets. We are using LA-URL at source configuration at bitmovin player. Please see our below code snippets.

var source = {  
title: ‘Demo’,  
dash: ‘[https://amsplaybackproxy.azurewebsites.net/ytmigratednew/ams-migration-output/asset-adbea63c-0efa-442c-aa4f-d5129a4eb73c/video\_AppleMusicUpNext\_AmyShark\_.mpd?token=rajesh](https://amsplaybackproxy.azurewebsites.net/ytmigratednew/ams-migration-output/asset-adbea63c-0efa-442c-aa4f-d5129a4eb73c/video_AppleMusicUpNext_AmyShark_.mpd?token=rajesh)’,  
drm: {  
clearkey: {  
LA\_URL: “[https://spherexlicenseserver.azurewebsites.net/api/bitmovin](https://spherexlicenseserver.azurewebsites.net/api/bitmovin)”,  
headers: {  
‘content-type’: ‘application/json’  
}  
}  
}  
};

In the above LA-URL post-API calls we are getting key ids as null, even though our goal is to return keys based on keyids. Can someone please explain what this place is lacking?  
We would appreciate for prompt reply from the community.  
Thanks

Hi @rajeshrai0512 , thanks for sharing your question. I did a quick test and found that Bitmovin player is sending ClearKey request with following payload which is as expected.

```auto
{kids: ["k-mXZeuFRQaQ2ieEjrzHtQ"], type: "temporary"}
kids
: 
["k-mXZeuFRQaQ2ieEjrzHtQ"]
type
: 
"temporary"

```

But the clearkey server(hosted at [https://spherexlicenseserver.azurewebsites.net/api/bitmovin](https://spherexlicenseserver.azurewebsites.net/api/bitmovin)) is returning a response with null values. Can you please check this on the server side for the reason for such response?

```auto
{keys: [{kty: null, k: null, kid: null}], type: "temporary"}
keys
: 
[{kty: null, k: null, kid: null}]
type
: 
"temporary"

```
