Invoke business process using C# code

13:21 Jul 17, 2025

Hello,

I am trying to invoke a business process from C# script. Below is my code,

ProcessSchema schema = UserConnection.ProcessSchemaManager.GetInstanceByName("Cw AI Process");

Process process = schema.CreateProcess(UserConnection);
process.SetPropertyValue("RecordId", Guid.Parse("e308b781-3c5b-4ecb-89ef-5c1ed4da488e"));
process.SetPropertyValue("RecordType", "Account");
process.Execute(UserConnection);
var result = process.GetPropertyValue("OutputVar");

And this is the error I am seeing. Both RecordId and RecordType are input parameters of the business process.

Property "RecordId" is missing in type "ProcessComponentSet".

Hi,

You will find it in academy : https://academy.creatio.com/docs/developer/integrations_and_api/busines…

or do something like this :

			var uc = Get&lt;UserConnection&gt;("UserConnection");
 
			var parameters = new Dictionary&lt;string, string&gt;() {
				{"vExerciceUsager", ExerciceUsagerId.ToString()},
				{"vRegleCalcul", RegleCalculId.ToString()},
				{"vBloc", BlocId.ToString()}
			};
 
			IProcessExecutor processExecutor = uc.ProcessEngine.ProcessExecutor;
			processExecutor.Execute(ProcessSchemaUId, parameters);
			return true;

Jerome BERGES,

Thank you I got that..
I have a question.. How do I read the value from output parameter.. Below is my code.. am I missing something?

UserConnection userConnection = UserConnection;
IProcessExecutor processExecutor = userConnection.ProcessEngine.ProcessExecutor;
/* Collection of incoming parameters.*/
var inputParameters = new Dictionary<string, string> {
["RecordId"] = "ecb-89ef-5c1ed4da488e",
["RecordType"] = "Account"
};
/* Collection of outgoing parameters.*/
var resultParameterNames = new string[] {
"strValue",
};
string processSchemaName = "UsrProcess_6ff6f";
/* Runs the process via the schema name using transferred incoming and received outgoing parameters.*/
ProcessDescriptor processDescriptor = processExecutor.Execute(processSchemaName, inputParameters, resultParameterNames);
string AiResponseValue = processDescriptor.ResultParameterValues["strValue"];

return true;

I never done this with output parameters, but it may be that your process is in background mode (which is not allowed), or your parameter is not of type "Output"
