You can also pass environment variables required for the pipeline execution in a JSON object to this method, and it is completely optional. This method returns the execution history details of the pipeline as the response. The `pipelines_service` reference used below is already defined in [this component instance page](https://docs.catalyst.zoho.com/en/sdk/nodejs/v2/pipelines/get-pipeline-instance). ```python execution_details = pipelines_service.run_pipeline("18014000000023048", "main", {"EVENT": "push","URL":"https://www.google.com"}) ``` A sample response is shown below: ```python { "status": "success", "data": { "history_id": "5000000021007", "pipeline_id": "18014000000023048", "event_time": "Mar 20, 2024 02:02 PM", "event_details": { "BRANCH_NAME": "main", "EVENT": "push", "URL": "https://www.google.com" }, "history_status": "Queued" } } ```
