# Missing HLR results

**Requesting an HLR only creates an HLR object**

An HLR request like below will not return the HLR status/details of the number (`msisdn`):

[`POST <https://rest.messagebird.com/hlr> \\ -H 'Authorization: AccessKey test_gshuPaZoeEG6ovbc8M79w0QyM' \\ -d "msisdn=31612345678" \\ -d "reference=YourReference"`](https://rest.messagebird.com/hlr)

Rather the response will be like below:

```
{
"id":"0da180b035398662ceb3c42h04904985",
"href":"<https://rest.messagebird.com/hlr/0da180b035398662ceb3c42h04904985>",
"msisdn":31612345678,
"network":null,
"details":[],
"reference":"YourReference",
"status":"sent",
"createdDatetime":"2016-05-04T07:32:46+00:00",
"statusDatetime":"2016-05-04T07:32:46+00:00"
}
```

You'll need to [View an HLR ](https://developers.messagebird.com/api/hlr/#view-an-hlr)to view the details of the msisdn.

If you are missing HLR results, check two things:

1. With the `id` for the HLR request, you can retrieve the status/details of the number with a GET request. You only need to supply the unique `id` that was returned upon creation of the HLR object: \
   `GET [<https://rest.messagebird.com/hlr/{hlrId}>](<https://rest.messagebird.com/hlr/%7BhlrId%7D>)`
2. Make sure you have your HLR callback url configured within the API settings in your Dashboard [**here**](https://dashboard.messagebird.com/en-gb/developers/settings)**.** The statuses for your HLR requests will be sent in this format:

`GET [<http://your-own.url/script?id=e8077d803532c0b5937c639b60216938&msisdn=31612345678&reference=YourReference&status=active&createdDatetime=2016-05-04T07:32:46+00:00&statusDatetime=2016-05-04T07:32:46+00:00>](<http://your-own.url/script?id=e8077d803532c0b5937c639b60216938&msisdn=31612345678&reference=YourReference&status=active&createdDatetime=2016-05-04T07:32:46+00:00&statusDatetime=2016-05-04T07:32:46+00:00>)`

&#x20;

Lastly, it is important to note that the HLR results / attributes can change over time and some of them can be null because not all information is available for all countries and providers.
