Fetch Image & External URL from Tweets with statuses/user_timeline API

问题

I wish to extract value for External URL present in the Tweet. Plus the generated Thumbnail of that URL.

Example Tweet:

http://prntscr.com/ogdqey

https://twitter.com/JarirBookstore/status/1151506848387870720

Output from Twitter statuses/user_timeline API -

                ]
            }
        ],

URL entity is a blank array. If the link is not present in the Tweet's text itself, API doesn't return it in the URL entity. I've tried with and without tweet_mode=extended

Surprisingly, Twitter does return URL for few such Tweets. One example is below.

https://twitter.com/BillGates/status/1150605518291001345

},

Why the response is random? It does return URL for Bill Gates' Tweet but not for the one mentioned earlier in my question.

How can I have both External URL and the Thumbnail displayed by Twitter?

My final API call -

https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=jarirbookstore&count=100&exclude_replies=true&trim_user=true&include_rts=false&tweet_mode=extended

The first of the two examples you provide is posted by the Twitter Ads platform, so the attached card is not part of the Tweet. There is no way to get that via the API. In the second case, the URL is part of the Tweet text, so it is also part of the URL entities object.
