Response

The call returns the standard response envelope. Check ResponseState first: a failed call still returns HTTP 200.

ResponseStatestring

Required

Success, Invalid or Error.

ErrorCodeinteger

0 on success, otherwise the error code. See Errors.

ReturnTask[]

Response<Task> with one item, external keys loaded. IsReturnPaged true and TotalPageCount -1 although it is a single item. No mapping: Error envelope - a normal outcome for a sync look-up.

Example response

HTTP/1.1 200 OK

Errors

All errors come back with HTTP 200: check ResponseState, ErrorCode and Messages. The errors every operation can return (expired or invalid token, API not enabled, HTTPS required, general errors) are listed once in Responses and errors.

Errors specific to this operation:

ResponseState	ErrorCode	Message	What it means	What to do
Error	40001	Error during call on TimeLog.API, Message 'The external key "{externalID}" was not found for the chosen external system "{systemName}".'	The system exists but no task is mapped to this key.	Create the contact first; a not-found is a normal outcome for sync look-ups.
