# Possible to Modify Field Constraints for "Application Name" of Murano Application Deployment?

## Problem

* A Heat template has been used to create a Murano application.
* Upon deployment of the application, an **Application Name** field is presented.
* It's desired to modify the field constraints, such as requiring all lower-case (as doable for other parameters in the Heat template).

## Environment

* Platform9 Managed OpenStack - All Versions
* Murano

## Answer

**No**, it is not possible to modify the constraints for the **Application Name** field, nor can it be validated by Heat as the application name is not included as part of the template parameters in the API payload. For example:

1. Request URL:

https\://\_\_CLOUD\_FQDN\_\_/murano/v1/environments/\_\_ENV\_ID\_\_/services 2. Request Method:

POST 3. Status Code:

200 OK

**Payload**:

{% tabs %}
{% tab title="None" %}

```none
{?: {classVersion: "0.0.0", package: "io.murano.apps.generated.Apachehttpserver",…}, name: "apache",…}  ?: {classVersion: "0.0.0", package: "io.murano.apps.generated.Apachehttpserver",…}  name: "[application-name]"  templateParameters: {flavor: "[flavor]", image: "[image-id]", key_name: "[ssh-key]",…}
```

{% endtab %}
{% endtabs %}
