Email Template - Getting User First Name From the Input

wilderichsophus if this is possible to call api from your context, you could easily get user first_name and last_name.

<#assign apiVersion = "2.0"/>
<#assign user_id = 'user-id'>
<#assign userQuery = "select first_name,last_name from users where id = '${user_id}' "/>
<#assign usersData = rest(apiVersion, "/search?q=" + userQuery?url).data.items[0]/>
${usersData.first_name}
${usersData.last_name}
