I'm trying to pass a JSON string from within a powershell script to the build.phonegap.com api, using curl.
According to phonegap's forum, when running on a Windows machine, the JSON data has to be formatted as:

curl.exe -ku user@email:mypass -X PUT -d "data={\"password\":"\keypass\"}" https://build.phonegap.com/api/v1/key 

Indeed, this does run fine when invoked from the command line.
However, when I try to invoke this from within a powershell script, the double quotes seem to be stripped.

So far, I have tried:

• Putting the JSON in single quoted string:

 curl.exe -ku user@email:mypass -X PUT -d '"data={\"password\":\"keypass\"}"' https://build.phonegap.com/api/v1/key

• Putting the JSON in single quoted string, without the DOS escape backslashes:

 curl.exe -ku user@email:mypass -X PUT -d '"data={"password":"keypass"}"' https://build.phonegap.com/api/v1/key

• Putting the JSON in single quoted string, escaping the double quotes and backslashes (DOS style with a backslash):

 curl.exe -ku user@email:mypass -X PUT -d '\"data={\\\"password\\\":\\\"keypass\\\"}\"' https://build.phonegap.com/api/v1/key

• Putting the JSON in a double quoted string, escaping the double quotes with the powershell back tick character `:

 curl.exe -ku user@email:mypass -X PUT -d "`"data={\`"password\`":\`"build*2014`\`"}`"" https://build.phonegap.com/api/v1/key

Any idea how to achieve this?

Thanks for your time, Koen
