apple news api - promotedArticles

Hi,

Has anyone sucessfully used the promotedArticles endpoint and have any tips on getting it to work, I always get an invald UUID for the article I am trying to promote.

https://developer.apple.com/documentation/apple_news/code the invalid parameter states:

The specified article ID is not a valid

UUID.

data.promotedArticle

I have followed the doumentaion example

POST /sections/a3caeb08-b9db-4002-b379-cde305d74be7/promotedArticles HTTP/1.1

Host: news-api.apple.com

Accept: application/json

Authorization: HHMAC; key="1e3gfc5e-e9f8-4232-a6be-17bf40edad09";

signature="irqw07DCRQLtx/40Z2VhNc7sl3nB1PKII374R7AHjUQ=";

date="2017-12-08T00:03:31Z"

{

  "data": {

  "promotedArticles": [

  "F59D1784-CAFC-432A-9A1A-EF2FCE1E1C60",

  "2027DD1B-2794-4B0A-B9DC-F7EE696411FF"

  ]

  }

}

But always get this error, and can't determine why if anyone has got this working and has any tips.

PS I am using my own sites endpoint and data articles but always failing to promote an article with the errror {"errors":[{"code":"INVALID"}]}
