# refetchEventSources

> FullCalendar v3 documentation, for an old release. Web version: https://legacy.fullcalendar.io/v3/refetchEventSources
>
> Latest version (v7): https://fullcalendar.io/docs/EventSource-refetch.md

Refetches one or more specific event sources.

<div class='spec' markdown='1'>
.fullCalendar( 'refetchEventSources', sources )
</div>

The `sources` parameter can be a single identifier item, or an array of identifier items. An identifier item can be either an event source's id/Array/URL/Function **or** the full [Event Source Object](https://legacy.fullcalendar.io/v3/event-source-object.md).

Will result in a single re-rendering of events when all event sources are refetched.
