How can I get the image URL from a LinkedIn post using the Post API?

Question

I am trying to get the URL of all the media inside of an organization post but all I can get is the image URN. I don't want to do another request to get the image but rather get the Posts information and the URL on the same call.

I tried to use the Posts API as the UGC Post API is currently marked as Legacy.

let testresp = await axios.get(https://api.linkedin.com/rest/posts?q=author&author=`urn%3Ali%3Aorganization%3A${LinkedInHelpers.URNtoID(orgsRes.data.elements[0].organizationalTarget)}`&fields=id,content:(media), {
            headers: {
                'Authorization': `Bearer ${accessToken.data.access_token}`,
                'X-Restli-Protocol-Version': '2.0.0',
                'LinkedIn-Version': '202301'
            }
        })

I also tried to use the ~ decorator to get extra data on the Media but it returns an empty object.

Hello please try making the get request add this address instead https://api.linkedin.com/v2/ugcPosts/${postId}

Try this:

axios.get(`https://api.linkedin.com/v2/ugcPosts/${postId}`, { headers })
  .then((res) => {
    const imgUrl = res.data.media_url;
    console.log(imgUrl);
  })
  .catch((e) => {
    console.error(e);
  });
