Hi,

 

Sorry if this has been covered but I can't find anything in the swagger UI or on my check through the forum.

 

Is it possible to trigger the Refresh Guide task via API?

I wrote a C# utility to update the Emby guide after a NextPVR guide refresh and there was no single API call although Luke mentioned he might add one.

 

1) Loop through the scheduled tasks "http://{0}:{1}/emby/ScheduledTasks?IsHidden=false&api_key={2}"  to get the Task ID for the "Refresh Guide" category

 

2) Execute "http://{0}:{1}/emby/ScheduledTasks/Running/{2}?api_key={3}"  to refresh the guide.  {2} is the task ID

Does yours still work?  I wrote one that does the same thing that I was using a while back that uses the dot net sdk and it worked great.  But the sdk broke a while back with one of the recent server updates.  @@Luke mentioned it needed updating.  Has it been updated?

Would you mind sharing that code/solution?  I'd love to get something working again.

Just take out the NUtility and Logger message and it should work
