The Box View API provided an image of the first page of a document as it's thumbnail - while investigating the preview.js functionality, I was attempting the same call for thumbnail using box-java-sdk and noticed it was the generic PDF file image instead of a first page preview. Is there any way to simulate the view version of thumbnail in the new API?
Question
Box API Thumbnail Image for Documents
Any news on this? same goes with box-node-sdk, in Crocodoc you used to have a thumbnail for documents, in this api you don't seem to have one?
See this https://codepen.io/box-platform/pen/WEwXQy
What they do instead is generate representations for files, you can get them here
https://developer.box.com/v2.0/reference#representations
Then based on the available type (png or jpg) and available resolution (1024x1024) you can do a request to the info.url to trigger boxview to generate that image, you can then proceed to call representations again but with the X-Rep-Hints header specifying the type and resolution that you want, it will give you a content object with a url_template variable, where you replace the {+asset_path} part of the string with the page number that you want, for example for a png at 1024x1024 and page 1 you would replace it with 1.png
you need to call it while passing the auth header like so, adding the token as a parameter in the url will make it all not work.
Authorization: Bearer ACCESS_TOKEN
convoluted, but I got it to work in php 🙂
