***How do I retrieve null and zero values?***

Validic stores all information retrieved from integrated data sources regardless if the data retrieved has meaningful value or simply null and zero values. However, Validic's standard API responses do not anymore include records with only null and zero values.

Should you need to retrieve these records in order to have a complete set as is available from the source, pass an "`allow_null=1`" parameter to the API call, for example:

```
GET https://api.validic.com/v1/organizations/{ORGANIZATION_ID}/biometrics.json?access_token={ACCESS_TOKEN}&allow_null=1
```

This would return records with null and zero values, for example:

```
