Get request image url

Help Hub
1

Hello,

I am trying to make a simple GET request to a local headless cms (strapi). In principle the request works, I get information about the title etc. what I don’t get is the url of the images that are in the article. I tried ‘popualte=*’, but then I only get the info that there is a linked media file in the blocks.

…

“blocks”: [
{
“__component”: “shared.media”,
“id”: 29
},

…

How do I get the url of the images?

Best regards
Jens

Hey @cryosat-geoscienti33 :waving_hand:

Welcome to the Postman Community! :postman:

Is this a public API that has documentation that could be shared?

Without know the API and how it’s been implemented, it’s difficult for anyone to know what filters/parameters/etc are available on the endpoints.

Hello Danny,

thanks, Strapi is an open-source CMS, I found this in the documentation.

Does that help?

Many thanks and best regards
Jens

Hey @cryosat-geoscienti33,

Can you please try the following GET request?

/api/articles?populate[blocks][populate]=media

It should return full media info, including image URLs.

Unfortunately it does not work, I get this error message:

{
    "data": null,
    "error": {
        "status": 500,
        "name": "InternalServerError",
        "message": "Internal Server Error"
    }
}

When I access a single article with its ID I get the answer

/api/articles/msyhpknnmyjgj4jf3lim7p0q?populate=blocks

{
    "data": {
        "id": 30,
        "documentId": "msyhpknnmyjgj4jf3lim7p0q",
        "title": "Artikel 01",
        "description": "Das ist ein Artikel",

        "publishedAt": "2025-07-11T12:35:17.426Z",
        "blocks": [
            {
                "__component": "shared.media",
                "id": 29
            },
            {
                "__component": "shared.media",
                "id": 30
            },
            {
                "__component": "shared.rich-text",
                "id": 27,
                "body": "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

            },
            {
                "__component": "shared.media",
                "id": 31
            }
        ]
    },
    "meta": {}
}

The 500 error might be due to some misconfigured component. You can continue by getting a single article using it’s ID:

/api/articles/{article_id}?populate[blocks][populate]=media

unfortunately does not work either, i get this error message in cmd:

to indicate all second level links. Specific field targeting is not supported here. Consider using the fragment API for more granular population control.
