Deviation on SL.se but not in API
Hi.
On SL.se I can see the upcoming event "Pendeltåg linje 35, 36 och 38
Inställd trafik mellan Stockholm C och Älvsjö under påskhelgen
Gäller från: 2017-04-13, 22:25"
But somehow this is not returned by http://api.sl.se/api2/deviations.json
Why is that? Is there some default date range filter applied when I don't set the fromDate and toDate params? Because this is not documented. Or is this just a temporary glitch?

If you don't define FromDate/ToDate parameters you get the deviations valid at the time of the request. The "missing" deviation was valid from some days after your question according to the quote above, which is why it wasn't returned.
This information will be added to the documentation.

As Sabina has pointed out, omitted ‘fromdate’ and ‘todate’ parameters will result in deviations valid at the time of the request.
In order to get valid deviations for any given day your API call should look like this:
http://api.sl.se/api2/deviations.json?key=[your_api_key]&fromdate=2017-04-13&toDate=2017-04-13
The date format is 'yyyy-MM-dd'.
You are not allowed to specify more than ONE day in the range, because of the current API restrictions.
And I do have a related question: The deviationsraw endpoint does not support the filtering for dates right? Does this one also just return currently active deviations? or is there a way to get the coming deviation from that endpoint too?
Thank you for your patience and help!
