`create(project, managedZone, body=None, clientOperationId=None, x__xgafv=None)`

    Atomically updates the ResourceRecordSet collection.

    Args:
      project: string, Identifies the project addressed by this request. (required)
      managedZone: string, Identifies the managed zone addressed by this request. Can be the managed zone name or ID. (required)
