How to pass package variable for release template from Create Release from Template Rest API?

Hi
I am using Create Release from Template API to create a new release in BuildMaster. I have defined some package variable in the Release Template to which value is assigned by user when package is created. Here in case of Rest API, i am able to create a new release with release template but when i am passing the package variables to the API using JSON , they are not reflecting in BuildMAster Package. Here is the JSON object:
$CreatePackageParam= @{releaseNumber=$ReleaseNumber;
applicationName=$ApplicationName;
$SiteName=$SiteName;
}
I have prefixed key with $ as mentioned in BuildMaster documentation to pass any number of variables. However it is not working with or without $. Please help how can we pass and consume other variables in Rest API?

Product: BuildMaster
Version: 5.6.11

Hello Megha,

In PowerShell, to create a JSON object key with a dollar sign in it, you need to use this syntax: "`$KeyName"

So your object would look like this:

$CreatePackageParam= @{releaseNumber=$ReleaseNumber;
applicationName=$ApplicationName;
"`$SiteName"=$SiteName;
}

Otherwise, PowerShell replaces both instances of $SiteName with the value in that variable.
