Most of our customers ingest their content using the Feed method. If you are not sure which method to use, we recommend starting with Feed.

The Feed method allows you to:

  • Receive a stream of new content as it is published by the AP.

  • Limit the number of duplicate items downloaded and ensure you are not missing any items.

Getting Content Updates Using Next Page Links (02:40)

Description

Returns a feed of content matching the specified criteria. The returned feed items are sorted in chronological order, with the newest items at the bottom of the feed.

Feeds are used for content ingestion - monitoring a stream of content to receive all updates and new content going forward. To learn more, see Typical Feed Workflow and Feed Examples in Getting Started.

About Long Polling

For efficiency on feed requests, the AP Media API server uses HTTP long polling where the server holds the client's feed request open until new content becomes available or up to 15 seconds. If there is new content when your client application makes the feed request, this content is immediately returned. Otherwise, the content is returned as soon as it becomes available during the next 15 seconds. An empty response is returned only if no new content is available after 15 seconds, which helps minimize the number of empty responses and improves efficiency.

 

  Tip

 

To receive your AP breaking news content in a timely manner and to ensure your feeds do not get behind, follow the next_page link as soon as it is returned in the feed. There is no need to wait any period of time between your polling requests.
