Hi Thomas,
We currently do not have code examples for what you require. However, you can still refer to the old
guide as the process of creating the feeds and feedItems should still be similar. The naming of the involved services also remains the same such as the
FeedService,
FeedItemService, and
FeedMappingService.
Should you have additional clarifications, feel free to write back and I'll be happy to assist you.
Thanks and regards,
Peter
