rdp news api how to get data in raw

Julian.Bai

Hi team, i was trying to use refinitiv.dataplatform to get news data using below code.

import refinitiv.dataplatform as rdp

rdp.open_platform_session(

'appkey',

rdp.GrantPassword(

username = 'id',

password = 'pwd*'

)

)

html_story = rdp.get_news_story('urn:newsml:reuters.com:20230714:nL8N390167:3')

But in html_story, i was only able to fetch story body, without the info from raw data in api playground, like topic codes, sentiment and others, shown in pic below. Which function should I use to get those data, or am I using the correct api? Thanks in advance for answering.

Thank you for reaching out to us.

To get the raw news story, you can use the following method in RDP.

news =  rdp.news_story.NewsStory(rdp.get_default_session())
story = news.get_story("urn:newsml:reuters.com:20230717:nNRApblhyf:1")
story.data.raw

The output is:

However, I suggest using the Refinitiv Data Library for Python instead. The examples are available on GitHub.

response = news.story.Definition("urn:newsml:reuters.com:20230717:nNRApblhyf:1").get_data()
response.data.raw

The output is:

I also found python code provided in api playground which is response or http format like shown in the pic. How was the 'headers' generated?

Hi Jira, thanks for the advice! Will try and revert!

Hi Jira, I tried the first part of code but it failed to fetch any data from RDP, error msg to be 'Error while calling the NEP backend: Insufficient authorization for requested information'. I used the userid and pwd of api playground, together with appkey generated in App key Generator. Is that the correct way to authentication?

Yes, it uses the RDP credentials.

rdp.open_platform_session(
    APP_KEY, 
    rdp.GrantPassword(
        username = RDP_LOGIN, 
        password = RDP_PASSWORD
    )
)
news =  rdp.news_story.NewsStory(rdp.get_default_session())
story = news.get_story("urn:newsml:reuters.com:20230717:nNRApblhyf:1")
story.data.raw

That worked, thank you very much!
