The following payload is sent to your configured webhook URL when a job finishes. 
{
    "job_id": "job_XXXX",
    "status": "success",
    "dataset": "dataset_XXXX",
}
If a Parse job is created without a dataset, the dataset field will be null. The possible statuses are:
  • created - The job is created.
  • success - The job finished successfully.
  • failure - The job failed to finish.
