Getting multiple thumbnails of multiple files at once ?

Oh I see, thanks Greg for helping me to know more about the v2 API.

Hi Greg,

One more question please. I tried a get request to this endpoint https://content.dropboxapi.com/1/thumbnails/auto/IMG_8199.jpg with authentication token in the header and it works great. My question is: Will this get endpoint continue to be supported after 6/28/2017 when the api v1 is turned off since the end point host is from v2 but it still contain 1/ in the url. Please advice.

Thanks,

The /1/thumbnails endpoint is part of API v1 and will not be available after API v1 is retired. (The different hosts, e.g., api-content.dropbox.com and content.dropboxapi.com, are not tied to specific versions of the API. They each currently serve both API v1 and API v2.)

Oh ok, thank you very much.

Hi Greg,

You mentioned that the api v2 does offer a way to get thumbnail as v1 (https://content.dropboxapi.com/1/thumbnails/auto/IMG_8199.jpg?size=s&access_token={mytoken}. I tried it but it never worked for me without /1/thumbnails, I even tried to replace /1/thumbnails with /2/get_thumbnail but no use. Do you have any example url/endpoint where it's showing access token from the url other than the one from v1 so I can look at ?

Thanks,

The different versions of the API work differently, so it won't be a matter of just replacing /1/thumbnails with /2/get_thumbnail. For API v2, you'll need to use the 'authorization' and 'arg' URL parameters, per the documentation I linked to earlier:

 

https://www.dropbox.com/developers/documentation/http/documentation#formats

 

For example, getting the thumbnail for a files at /test.jpg would look like this:

 

https://content.dropboxapi.com/2/files/get_thumbnail?authorization=Bearer%20ACCESS_TOKEN_HERE&arg=%7B%22path%22%3A%20%22%2Ftest.jpg%22%2C%22format%22%3A%20%22jpeg%22%2C%22size%22%3A%20%22w64h64%22%7D

Hi Greg,

I tried the provided url with my token and an actual image path, but I got a weird error message saying "Error in call to API function "files/get_thumbnail": Your app is not currently allowed to use API v2". Wonder how this happens since I have been using v2, it's not that my app is still on development mode, I haven't submitted/requested for production yet. Wonder if this is why.

Thanks,

That error isn't related to your app's development or production status. Did you potentially use an access token for an app with the "file type" permission though (as opposed to full Dropbox or app folder)? The file type permission isn't supported by API v2.

I replaced the token and it worked, but I'm actually looking for endpoint that return image/jpeg or image/png Content-Type like v1, not application/octet-stream. Is it even possible to do it with the api v2 ?

I am aware that the api does not support returning thumbnails/templinks in bulk from the thumbnail and templink end points. But since the api support returning metadata in bulk from the list_folder endpoint, therefore I wonder if there is a way to include templinks or thumbnails from list_folder response that is not defined from the official api document.

Thanks,

The Content-Type header is reported differently (image/ in v1, and application/octet-stream in v2) but the actual thumbnail data returned is the same. Is the Content-Type header itself causing issues in your use case? I'll be happy to pass this along as feedback, but additional context would be helpful

 

Anyway, no, there isn't another way for getting temporary links or thumbnails like you describe that I can offer.
