GetWOListByUpdated

Lists the IDs of the work orders whose event or data field with a given code was saved in a period. An integration calls it on a schedule to pick up what changed in TrakIT, for example every work order whose gate-out event was recorded since the last call, then reads each one with GetWO or reads just the values it needs with GetSeqData.

GET /api/v1/GetWOListByUpdated?Code=GATEOUT&FromDate=2026-10-27&ToDate=2026-10-27T23:59:59&WFID=12
Token: your-token

Parameter	Required	Meaning
Code	Yes	The code of an event or data field, for example GATEOUT. Capitals do not matter. Show Codes on a work order’s Events tab shows the codes.
FromDate	Yes	The start of the period, in UTC: a date, yyyy-MM-dd, or a date and time, yyyy-MM-ddTHH:mm:ss.
ToDate	Yes	The end of the period, in UTC, in the same form. At most 365 days after FromDate.
WFID	No	Only the work orders of this workflow: its ID, a whole number, as in the ID column of Workflow Definitions. The default, 0, is every workflow.
JobType	No	Only the work orders whose job has this job type, among others: the job type’s ID, a whole number. TrakIT Support can give you the IDs. The default, 0, is every job type.

• Send Code, FromDate and ToDate. Without one of them the request does not reach the endpoint, and TrakIT answers with HTTP status 404 (see Errors).
• Both ends are included. A date without a time means midnight at the start of that day, so ToDate=2026-10-27 leaves out what was saved later on 27 October. To include that whole day, send 2026-10-27T23:59:59 or 2026-10-28.
• Write a time with the T, as above. TrakIT removes spaces from the dates, so 2026-10-27 23:59:59 is refused. See Dates and times.

What counts as a change

A work order is listed when the value of its event or data field with that code was last saved in the period, its Updated time in GetWO. Only the last save counts: a value saved in your period and again after it is listed only in the later period. Ask for back-to-back periods, each starting where the last one ended, and every work order whose value is saved is listed at least once.

Work orders of every status are listed, closed and cancelled ones included. A work order whose workflow has no event or data field with that code is never listed.

Response

On success, RetInfo lists the work order IDs, in ascending order, each once, and RowsAffected is how many there are.

{
  "Code": 1,
  "Info": "",
  "RetInfo": [48211, 48212, 48305],
  "RowsAffected": 3,
  "Scalar": null,
  "Identity": 0
}

When no value with that code was saved in the period, the answer has Code 0 and Info No data found.
