Eroor 400 when using the Dropbox choose API
Hi, I am trying to consume the Dropbox choose API as from the below link: https://www.dropbox.com/developers/chooser However, when the chooser window is shown, it ends up with error 400. ...
We do not currently include the MIME type in the response from metadata returned by the Chooser. I have filed this as a feature request for the Chooser.
In cases where the returned file name includes a file extension, is it possible to infer the MIME type from the file extension?

Can you share the full URL of that page that's showing the 400 error? That would help us look into this. Thanks in advance!
Hi
I'm getting the same error, and here is the full URL
https://www.dropbox.com/chooser?origin=https%3A%2F%2Fhttp://a9b7088a.ngrok.io&app_key=0ro4ue0jd0uqghq&link_type=preview&trigger=button&multiselect=false&extensions=&folderselect=false&iframe=false&version=2

dolphin-newbie It looks like the issue is that you don't have the domain you're running from pre-registered as a Dropbox Chooser/Saver domain on the app's page on the App Console. You need to pre-register the domain(s) you'll be using your app key on so that other people can't use your app key on their own sites.
In this case, you'd want to register 'a9b7088a.ngrok.io'. To do so, go to the App Console, click on the app with app key '0ro4ue0jd0uqghq', and enter 'a9b7088a.ngrok.io' under "Chooser/Saver domains".
Thanks for the reply @Greg . I actually do have the server domain specified.

dolphin-newbie Taking a closer look at the sample URL you shared, I see your 'origin' value is actually "https%3A%2F%2Fhttp://a9b7088a.ngrok.io", which decodes to "https://http://a9b7088a.ngrok.io".
That's not valid, as it contains two protocols (both "https://" and "http://") for some reason. Can you check that you have a valid URL with just one protocol for the page where you're hosting your Chooser integration?
