Feed API v2

The Feed API V2 is the way you retrieve article content from system feeds. It has examples of how to interact with the feed, and how to parse published URLs back for uninterrupted posting of social posts that promote article content.

Host – https://api.newscred.com
Path – /v2/feed/{id}

Your Implementation Consultant will give you the ID of the feed or feeds that you will interact with, during onboarding. These may also be found in the settings menu, under Website, CMS & Feeds and is accessible to Administrator accounts only.

Call the feed

The Optimizely Content Marketing Platform (CMP) lets you create an arbitrary amount of feeds that you can retrieve via HTTPS GET requests. Using CMP workflows, you can publish articles to the top of one or more of these feeds. Then, by calling your feed endpoints regularly, you can check for new content, and where it exists, create a new article in your CMS database by mapping fields (article headline, body, author, source, metadata, and so on) to their respective elements in your CMS. You will be given your feed in a structure similar to below

<https://api.newscred.com/v2/feed/0569f69ed223720c699936eddbc7tyxP8d3>

By default, accessing the URL returns up to 200 records in Atom format. To work with the feed, you can use the provided parameter options.

Feed parameters

You can use the following parameters when you call the feed.

Parameter	Type	Values	Default	Explanation
Format	string	json, atom	atom	The Feed API supports both Atom and JSON. Based on how you plan to integrate, choose your preferred format.
pagesize	integer		200	This parameter tells our API how many pieces of content you want to retrieve
offset	integer		0	An offset can be applied in order to call articles in batches, when used in conjunction with pagesize and determines where you want to start. To retrieve the second page of content, increment the offset by the page size.
sort_by	string	Position, modified_at	Position (no value passed) or modified_at (other value passed)	Sorting of articles within the feed

Update and delete content

You should set a batch task that paginate through full feeds.
You should use a Deleted Feed so that the user can move an article to the Deleted Feed in the NewsCred Platform. Your integration can then be set-up to recognize when an article is moved and trigger the delete action when the feed is called from your CMS.
You can also delete the content in the CMS, but you should not allow inconsistencies to develop between the feed and the CMS to avoid unexpected behavior.

Invalid feed GUID

With a feed GUID that does not exist the server will respond with HTTPS status code.404

cURL – https://api.newscred.com/v2/feed/
HTTPS/1.1 404 NOT FOUND
Content-Length: 121

X-Request-ID:c384254ec33011e58a070242ac110002

{
  "error": {
    "code": "404",
    "message": "Collection with guid 0569f69ed223720c699936eddbc5b123 not found"
  }
}

Integrate with a third-party CMS

By attaching custom fields or labels to your CMP workflow, you can send additional structured data to your CMS. In the CMP, these can be populated with a dropdown, radio button, checkbox, free text or date interface and retrieved from the “custom_fields” node in the feed. A best practice is to create custom fields for meta tags such as Meta Title and Meta Descriptions to enhance on-page SEO. Ensure that the custom fields are then mapped onto the CMS during ingestion accurately.

Ensuring that the content delivered from the CMP is consistent with the website’s style.

Licensed content and, by default, custom content is delivered in purely semantic HTML. This means that while you still can take advantage of h tags (for example), they are interpreted by your website’s global style. The text editor allows the use of inline styles through raw HTML editing in cases where that is needed, but the standard interface is designed to prioritize the use of semantic HTML only.

Update and delete content

Using the fields parameter, you can retrieve only the GUID and modified_at elements of the feed. By calling the feeds with pagesize=999 and these fields only to minimize response size, you can determine if an article was deleted (GUID of an existing article is no longer present) or updated (GUID matches and modified_at was updated since last poll time).
You should set a batch task to paginate through full feeds that can be instigated by an editorial user.
You should use a Deleted Feed so that the user can move an article to the Deleted Feed in the NewsCred Platform. Your integration can then be set-up to recognize when an article is moved and trigger the delete action when the feed is called from your CMS.
You can also delete the content in the CMS, but you should not allow inconsistencies to develop between the feed and the CMS to avoid unexpected behavior.

Feed and social publishing

To post article content to a social channel, you need to have the canonical link of that article in the content body. Clients who rely on feed publishing need to be able to publish to a feed and any social channel from the CMP within a single task. For the social post to be sent without error, the published URL needs to be sent back to the platform once published.

This API that receives the tracking pixel and the canonical link of the article, finds out which article it points to and accordingly updates the article with the canonical link to let a social post be sent.

After the article is updated, the CMP is notified of this change, and if there are pending social publishes dependent on the article post, it proceeds with the publishing at that point or by the user-determined schedule.

A CMS-specific plugin calls the API service with the required data whenever an article is published in the hub. Feed clients need to handle this in their integration app, as below

Update canonical link endpoint

The following API endpoint is used to register the article URL to Newscred assets.

GET https://js-snippets.newscred.com/customer_canonical_link

Property	Format	Description	Example
canonical_link	String	The URL encoded link to the article page	https://cmc-wp-test.newscred.com/index.php/2017/11/22/puretech-health-to-present-at-piper-jaffray-2017-healthcare-conference/
tracking_pixel_key	String	This is the Newscred unique ID for the article. Usually found in the feed through the pixel_key property.	YXJ0aWNsZT0xNjcxOGNiNmZlZWEyNTM2OWZmMzZlZDBmZmJiZTJkOA==

Dynamically resize images from the NewsCred API

The NewsCred API passes raw images that can be rendered onto your site, iOS app, newsletter, or wherever you're displaying the content.

The images can also be sized by our server so that they fit your design specs. You won't worry about having to resize images client-side if you include the fitting height and width parameters. If you need to change both the height and the width, we've got you covered. The image won't get skewed or lose the integrity of its aspect ratio. Instead, the server will either crop the image or letterbox it to make sure it always looks like the original.

The following parameters can be attached to the end of the URL:

height – Change the height of the image
width – Change the width of the image
center\_height – Define center height position for cropping
center\_width – Define center width position for cropping

When your system parses the feed, you can programmatically add the URLs:

large – https://images-cdn.newscred.com/Zz01ZTIzZmM5OGNkYzg4OTdkMjRiZDc1ZGIwODQ3MDFhMw==

You can take that image URL and append it with this: ?width=600&height=600

For example, the following image is set to a width and height of 500:

https://images-cdn.newscred.com/Zz01ZTIzZmM5OGNkYzg4OTdkMjRiZDc1ZGIwODQ3MDFhMw==?width=500&height=500
