Updating variable within a process step

I am using the client SDK in c# to create hundreds of project resource based on a template (which is also a project resource). I am cloning the template. For some of the steps in the template I need to update variables for each process resource accordingly.

I want to automate the whole process of creating a process template. Is there a way to update a variable within a process step using the client SDK?

    If you want to update the variables of a project, we have https://github.com/OctopusDeploy/OctopusDeploy-Api/blob/master/Octo... script that does that.

    Would this help?

    Hi John,

    Are there plans to support this in the C# sdk?

    Thanks for your help!

    Anything you can do in Powershell, can be done in C#, have a look at the scripts in https://github.com/OctopusDeploy/OctopusDeploy-Api/tree/master/Octo...

    Also, one way to figure out what needs to be called is to drive the ui with the dev tools network tab opened and see what requests are being made.

    Hope this helps

    Hi John,

    Thanks for the info. I ended up using the Powershell script. But it took me some time to figure out how to call it from C# :) . I realized I had to remove the Process {} wrapper from the script you provided.

    Here is the code In case some else needs to do this it will safe some time.

    using System.Management.Automation;
    using System.Management.Automation.Runspaces;
    the dll is located under
    C:\Program Files (x86)\Reference Assemblies\Microsoft\WindowsPowerShell\3.0

    using (var runspace = RunspaceFactory.CreateRunspace())
            var script = File.ReadAllText("MyScript.ps1");
            var ps = PowerShell.Create();
            ps.Runspace = runspace;
            ps.AddCommand("MyFunction").AddParameters(new Dictionary<string, string>
                { "Param1" , value1},
                { "Param2", value2},
                { "Param3", value3},

            foreach (var result in ps.Invoke())
        catch (Exception ex)
    Important, I also had to remove the process wrapper attribute from the script file


        function MyFunction
            Param (
                [Parameter(Mandatory=$true)][string] myParam1,
                [Parameter(Mandatory=$true)][string] myParam2,
                [Parameter(Mandatory=$true)][string] myParam3,
            // Removing the Process wrapper solved the problem, the code didn't run with it
            Process {
