# JSON field constraints

Submit your requests to define JSON field constraints through the service request form on the [Support Portal](https://support.pingidentity.com/s/).

## About this task

You can define a number of constraints for the fields included in JSON objects stored in values of a specified attribute type. For example, you can require that a field value is a specific data type, specify whether a field is required or optional, or restrict values of string fields to a predefined set of values.

Learn more about these values in [About managing JSON attribute values](https://docs.pingidentity.com/pingdirectory/latest/pingdirectory_server_administration_guide/pd_ds_manage_json_attr_values.html) in the PingDirectory documentation.

## Steps

1. Complete the following fields:

   * **Subject**: Enter a description of your request, including the action to be taken.

   * **Environment Type**: Specify the type of environment affected by this request.

   * **Proposed Change Window**: Specify the dates or times in which you want the work complete.

2. In the **Capability** list, select **PingDirectory service requests** > **JSON field constraints**.

3. In the **JSON attribute** field, specify the JSON attribute for which a field will be created.

10. Select the **Allow empty object** option to allow empty objects in the field.

11. Select the **Index values** option to create an index for this field.

12. In the **Business Priority** list, select the appropriate description:
