Here is the list of the status codes used to maintain the workflow statuses. This list might be useful when anyone creates a view based on workflow status. If you are creating a view for a list filtered by the workflow status, you would need use the number rather than the words (e.g. 2 instead of In Progress, 4 instead of Cancelled etc)
| Status | Value |
| Not Started | 0 |
| Failed on Start | 1 |
| In Progress | 2 |
| Error Occurred | 3 |
| Canceled | 4 |
| Completed | 5 |
| Failed on Start (retrying) | 6 |
| Error Occurred (retrying) | 7 |
| Canceled | 15 |
| Approved | 16 |
| Rejected | 17 |
