Hi.I can see there are some custom properties available for sites. The site webscript: <#if site.customProperties?size != 0>
"customProperties" :
{
<#list site.customProperties?keys as prop>
"${prop}" :
{
"name" : "${prop}",
"value" : "${site.customProperties[prop].value?string}",
"type" : "${site.customProperties[prop].type}",
"title" : "${site.customProperties[prop].title}"
}
<#if prop_has_next>,</#if>
</#list>
},
</#if>How do I create these custom properties in my webscripts?
