File not found when downloading file through API

mhaan

Hi,

We try to download the files attached to our references according to the instructions: https://www.zotero.org/support/dev/web_api/v3/file_upload under 'ii. Download the existing file'.

However, we get a 404 error doing this, even though there is a file in Zotero. The references are in a shared library, so we don't know if that makes any difference. We tested it using /users, but also groups and both result in a 404 error.

Are there any tips to get rid of the 404 error?

Thanks in advance.

Can you access the file online in the web library? It's either a file that's not synced or something is wrong with your API call (for more API questions, please use the zotero-dev group https://groups.google.com/g/zotero-dev/)

Hi Adam,

We first do a request to the Zotero API, to get the file URL:

$url = "https://api.zotero.org/groups/5349535/items/WY2YNJND"

$options = [
"timeout" => 0
"connect_timeout" => 0
"delay" => 0
"headers" => array:2 [
"Authorization" => "Bearer xxx"
"Zotero-API-Version" => 3
]
"stream" => true
]

That gives me a response with metadata, of which I use the uri. In the publication I'm testing with, this uri is: https://api.zotero.org/groups/5349535/items/WY2YNJND - but when I then redirect the user to this url, the user gets a blank page with the text "Not found"

So I think I'm doing something wrong, but can't really find anything in the documentation about what that might be?

I assume you mean /file/view for the URL?

I'm not clear what your use case is, but you can't redirect an external user to an API URL in a private library, if that's what you mean, since it requires authentication. You can download a file to your servers (using /file rather than /file/view) and serve the file yourself, but we don't support public file sharing.

Hi,

Thanks for the quick responses! Fixed it with the /file addition in the url and a local download
