**Description**  
I am building an app to maintain a given user’s state across their Zoom tools - presence, meetings and phone. I note that the user’s user ID is in both **phone** events and **user** events - except that the case is different.

I need a single hash that contains the user’s current state: both presence and phone status. I think the user’s ID is ideal for the hash key. But why do we see inconsistent case across these event types? If I use case-insensitive keys do I run the risk of the key not being unique?

See the _payload.user\_id_ element below:

```auto
{"event":"phone.caller_ended","payload":{"account_id":"XXXXXXXX","object":{"call_id":"7105913388545705085","caller":{"extension_id":"XXXXXXXX","extension_number":779,"phone_number":"779","user_id":"CsNUP4DxQam2ojhcDzgGSA","timezone":"Pacific/Auckland","device_type":"PolycomVVX-VVX_250-UA/6.4.2.3176","extension_type":"user"},"callee":{"extension_number":999,"phone_number":"999","extension_type":"commonAreaPhone"},"ringing_start_time":"2022-06-06T00:13:08Z","call_end_time":"2022-06-06T00:13:16Z","handup_result":"Call Cancel"}},"event_ts":1654474396870}

```

Compare this to the _payload.object.id_ field below:

```auto
 {"event":"user.presence_status_updated","payload":{"account_id":"XXXXXXXX","object":{"date_time":"2022-06-06T00:13:57Z","email":"call@xxxxxx.com","id":"csnup4dxqam2ojhcdzggsa","presence_status":"Away"}},"event_ts":1654474437772}

```

As you can see, the values are the same but the case is different. Why is this?

**Error?**  
No error is encountered.

**API Endpoint/s?**  
Webhooks

**How To Reproduce**  
Create a webhooks app that includes both user and phone events. From a phone associated with a user, make a call and capture the webhook phone event. For that same user, change the user’s status in the Zoom app to **Busy**. Capture the webhook user event. Compare the IDs as described above.

**Additional context**  
None.
