Parameters available to SSM Automation when triggered by an AWS Service Catalog 'Service Action'.

When an SSM Automation is triggered by an AWS Service Catalog 'Service Action', are there any parameters available by default to the SSM Automation Execution that can help identify which "Provisioned Product" actually triggered the Service Action and in turn the SSM Automation? I analyzed the Trail and found that the "ExecuteProvisionedProductServiceAction" call contains provisionedProductId but the "StartAutomationExecution" call doesn't have any identifier that can link it to the provisioned product or the service action. Am I missing something here?
