On RebelMouse, we have the ability to ingest PA Media content as drafts in your Posts Dashboard every few hours.
Currently, a direct feed of content from PA Media will be ingested as drafts that are added to your Posts Dashboard. However, it can be configured so that the articles are published to your site automatically. The post author is listed as "Press Association" by default, but this can also be changed to an author of your choice.
Here's an example of how it looks in Entry Editor, complete with a PA Media credit and caption for each piece of media:
This can be easily done by adding the API for PA Media to your site. This is something our developers will need to do, so if you would like to ingest content from PA Media, email email@example.com or contact your account manager today.
