A project can be exported via the API by using a ComPfdexport command. This is demonstrated in the following C++ code snippet. Please note that pfd export is only possible if no project is currently active (identical to manual execution via GUI).

using api::Value;
using api::v1::Api;
using api::v1::DataObject;
using api::v1::Application;


int ExportProject(Api* apiInstance, DataObject* project, const char* filename)
{
 if (!apiInstance|| !project || !filename) {
   return 1;
 }
 
 //create an export command object
 DataObject* comExport = app->GetCurrentUser()->CreateObject("ComPfdexport","");
 if (!comExport) {
   return 1;
 }

 //configure the command object
 int error(0);
 app->DefineTransferAttributes("ComPfdexport", "g_objects,g_file", &error);
 if (error > 0) {
   return 1;
 }

 Value objects(Value::VECTOR);
 objects.VecInsertDataObject(project);

 Value args(Value::VECTOR);
 args.VecInsertValue(&objects);
 args.VecInsertString(filename);

 comExport->SetAttributes(&args, &error);
 if (error == 0) {
   //execute the export command
   comExport->Execute("Execute", NULL, &error);
 }

 comExport->DeleteObject(); //clean up
 apiInstance->ReleaseObject(comExport);

 return error;
}
