Hi, We need a java workflow to scan the contents of a shared folder on a daily basis. I have downloaded the examples and looked at AuthorizeExample which I ran with the parameters "test.app test.auth short_live_token". This code appears to requires clicking a dropbox link https://www.dropbox.com/oauth2/authorize?token_access_type=offline&response_type=code&client_id=XXXXX to get an authorization code which is then used to generate a token and then the token can be used to list files in a folder. How can this all be done on the backend without human intervention? Are there any examples I can look at? With AWS S3 it's easily done with an access key and a secret key, I was hoping it would be similar. Thanks, Jason

novotny Yes, the expiration is only about the access token. The refresh token doesn't expire (though can be revoked on demand). If the expiration has passed, the client will use the refresh token to get a new access token automatically.

Thanks to the Java TutorialExample, I am able to executeListFolderResult result = client.files().listFolder("");And see the folders in my own home directory. However, my partner shared a folder with me that I wish to see the files in but I don't see it listed. That prompted me to update the team scope permissions in my dropbox app (Is that needed here?). Once I did that I went down another rabbit hole where I could no longer get my authorization code from the link provided in the AuthorizeExample as I needed admin access based on adding these extra permissions. After my partner modified me to be an admin, I was able to get an updated access token and now when I try to do the following:ListSharedLinksResult res = client.sharing().listSharedLinks();I get an errorcom.dropbox.core.BadRequestException: Error in call to API function "sharing/list_shared_links": This API function operates on a single Dropbox account, but the OAuth 2 access token you provided is for an entire Dropbox Business team. Since your API app key has team member file access permissions, you can operate on a team member's Dropbox by providing the "Dropbox-API-Select-User" HTTP header or "select_user" URL parameter to specify the exact user Am I on the right path? Really, all I want to do is to be able to read the files from a shared folder. Any code snippets would be greatly appreciated. Thanks, Jason

If the shared folder appear there as a subfolder (let say named "SharedThings"), you need to put this name (properly formatted) as a parameter (i.e. "/SharedThings", not empty string). You might need to set recursive enumeration if the shared folder contains subfolder and you need to enumerate all of them in one cycle. novotny wrote:...

If the shared folder is in your home (as a subfolder there), you definitely don't need to make your life complicated. Otherwise you need it. You have to set your id as a user and the space (team folder) where your target folder reside in (aside of exact path - properly formatted).Hope this gives direction.

Thanks for the information. Below is a screenshot The existing code:ListFolderResult result = client.files().listFolder(""); while (true) { for (Metadata metadata : result.getEntries()) { System.out.println(metadata.getName()); } if (!result.getHasMore()) { break; } result = client.files().listFolderContinue(result.getCursor()); will write: Jason NovotnyMPSJasonNovotnyFingagejason.novotny@fingage.com’s filesGet Started with Dropbox.pdf But I wish to get access to the folder "AffinityInvestment". Can you please help me with the steps I need to do? In particular how do I "set your id as a user and the space (team folder) where your target folder reside in (aside of exact path - properly formatted)." do this in Java? Thanks, Jason

backend Java process to read a shared folder

Hi,

We need a java workflow to scan the contents of a shared folder on a daily basis. I have downloaded the examples and looked at AuthorizeExample which I ran with the parameters "test.app test.auth short_live_token". This code appears to requires clicking a dropbox link

https://www.dropbox.com/oauth2/authorize?token_access_type=offline&response_type=code&client_id=XXXXX

to get an authorization code which is then used to generate a token and then the token can be used to list files in a folder. How can this all be done on the backend without human intervention? Are there any examples I can look at? With AWS S3 it's easily done with an access key and a secret key, I was hoping it would be similar.

Thanks, Jason

Something more: don't try change 'expireAt'. Your code will fail!!! There are ways to optimize your code but you need to keep entire credentials object and serialize and deserialize it. Don't change anything by hands there.

Ok so just to confirm even if the hardcoded credential I pass in to create DBTeamClientV2 has expired already (i.e. I run this code next week), it will simply use the refresh token to obtain a new one and everything should work.
