Box for Developers

We’re new to Box and we have a client who wants to share files with us using the platform. On our side we want to integrate Box with our internal platform so we can pull the files in.  We created a platform app in the developer console and shared the service account email with the client.  The client then shared the folder with the service account.On our side, we can connect successfully via API using the access credentials provided during the platform app setup, but we are unable to accept the collaboration invite from the client, which is preventing the app from being able to see the contents of the folder.The documentation here says that we can just invite the service account like we would a normal user:A Service Account has its own folder tree, which starts empty. To give it access to existing content:By email: Invite the Service Account using its assigned email address, just as you would invite any other collaborator.Can anyone help point us in the right direction on this?  Should

Hello,I have a free Box Individual account. I would like to create a user-authenticated OAuth 2.0 application under a separate free Developer account, then authorize it to upload personal backups to my existing Individual account.This would be a private, non-commercial integration used only by me. It would upload encrypted backup files, download them for integrity verification, and delete older backups according to a retention policy. It would not use Box AI or Box Sign.Before creating the Developer account, I would appreciate clarification on the following:1. Is this ongoing, private use permitted without purchasing a paid plan?2. Does the free Developer account expire or lose functionality after 30 days? The Developer Sandbox Management FAQ describes it as an initial 30-day evaluation, while the Free Developer Plan documentation describes a free plan without clearly stating an expiration date.3. Can an OAuth application owned by the Developer account be authorized by my existing free

Hi ,I would like to retrieve the IDs of subfolders within a Box folder associated with a Salesforce record.I believe the box.Toolkit class's getFolderContents method might be useful for this purpose, but I'm not sure what information is returned in the FolderContents object.Could anyone clarify the following?What information does the FolderContents object contain? Is it possible to retrieve a folder ID by using the folder name as a key from the FolderContents object?Any advice or code examples would be greatly appreciated.Thank you in advance for your help!

I am receiving multiple errors when attempting to authenticate to Box via API (oauth2) started at approximately 8 AM CT this morning. Is anyone else encountering issues with Box API with your custom APPs? We have two custom apps in our organization, and they are both encountering issues. 

I can’t change redirect urls, all action fail, can’t add, can’t remove, can’t edit ​​​Box Developers Consolewith browser request Box cfg RequestResponse Body 

So, I used to be able to update the OAuth 2.0 Redirect URIs for an app, but I haven’t had to touch mine in a while. And now, whenever I try to change anything and click the “Save” button, nothing actually gets saved and an error popover shows up, warning, “Some changes on the Configuration Page could not be saved.”What’s up with this? Is there now some different way we’re supposed to do it?

I have a free developer account which has an App created in it which I use to access files for some of my clients. I access the clients files by having them share access with the service account within the app, generate a token for the service account using the https://api.box.com/oauth2/token endpoint, and can then hit several endpoints to interact with their files/folders, such as https://api.box.com/2.0/folders/:folderId/items. This generally works well and have not ran into any issues. A new client has custom Terms of Service set up for their enterprise. They have shared access with my service account, however when I send this request (https://api.box.com/2.0/folders/:folderId/items) using their folder id, I get a 404 saying folder not found (request id 66e17dihmcfldadh, for an example of that request). Upon further investigation I found this endpoint: https://api.box.com/2.0/collaborations?status=pending&fields=status,acceptance_requirements_status which returns one pending co

My BoxAccessList, using OAuth2, read only, is not working anymore (active since 2022). It seems somehow that access is blocked. Can someone find out what the root cause is and remove the block.

Free Developer account. Two User OAuth 2.0 Platform Apps on the same enterprise; both ENABLED. Authorization column shows "---" for both.Symptom on App A:- Authorize URL loads; login + Grant Access UI work- After Grant Access → Application Error / invalid_client on the authorize page- Never redirects to registered loopback URI; local catcher never gets ?code=- Token exchange never runs (Client Secret unused)Control: same authorize flow fails for both the free Developer app-owner login and a separate personal Box login (file owner).App B (sibling User OAuth on same enterprise) previously completed Grant successfully. Console config is the same class: User OAuth 2.0, redirect saved, Read+Write, unpublished, as-user off, CORS empty. Only intentional difference is the redirect URI (different loopback port/path for two tools).Already ruled out on our side: redirect typo (Details match Console), AI/Sign scopes on/off, authorize host, minimal client_id+response_type URL, Collaborators/Publish

Hi Box Support Team,We are running into an issue while collecting data from one of our shared customers.For data collection, we use the below API As-User header to access the customer's Box data.GET https://api.box.com/2.0/folders/{folder_id}/itemsWe have a customer where the authorization was configured using a user with the Co-Admin role. However, when we use this authorized user to collect data from another user who has either the Co-Admin or Admin role, the API returns a 403 Forbidden response.We would like to understand whether this is a known limitation of Box's As-User functionality or permissions model.Specifically:Can a user with the Co-Admin role, who has authorized our application, use the As-User header to access data belonging to another Co-Admin or Admin user? If this is not supported, is there any recommended approach to collect this data without changing the authorizing user's role to Admin? Are there any additional permissions, scopes, or configuration settings that wo

Request for Box Support/Engineering attention: inconsistent file-operation behaviorI’m doing a structured archival migration into Box and have encountered inconsistent behavior with file operations that is making it impossible to safely verify transfers.I’ve experienced: Upload operations failing unexpectedly. An upload endpoint returning an error indicating that the requested function was unavailable. Move operations appearing to fail without reliable confirmation. Other uploads subsequently succeeding normally. This isn't simply a question about how to use Box. The problem is determining whether file operations are actually completing reliably and how to verify them without risking the original source files.Because this is an archive containing authoritative source material, I am retaining every original until each transfer can be independently verified.Could a Box employee or technical support representative please acknowledge this and advise whether there are any known issues

Does anyone know where to get actual guidance/help in accessing Box with the .net sdk.  It looks like all of the developers seeking for assistance on this site never gets resolved. Thanks in advance.

I am a systems integrator building an OAuth 2.0 application used to migrate customer-owned content from Box to another DAM. The OAuth application is owned by my free Box Developer account, while each customer authorizes the application using their own Box user account. The migration contains approximately 200,000 files and will generate several hundred thousand API requests. Which account's Platform API allocation applies to these requests? Does the developer account that owns the OAuth application require a paid Platform/Business subscription for production use? The customer’s source account is Individual.

Can anyone please help with accessing box from vb.net.  I am having a heck of a time figuring it out after researching for days. Thanks

We are currently working on a project where we use the Box C# SDK (v5.x) to upload large files (100MB+) to our Box Enterprise account using the Chunked Upload API (CreateUploadSessionAsync). While standard single-part uploads work flawlessly for smaller files, large chunked uploads fail consistently.After creating the upload session and splitting the file into chunks, calls to UploadFilePartAsync return a 400 Bad Request (Digest Mismatch) response.anyone help?

Persistent operationInProgressError on folder hierarchyI own a Box folder that has been unable to be moved or deleted for several months, though I can rename it. It contains four empty subfolders, which I can also rename, but not move or delete. I cannot move a newly-created folder into the affected folder. I reproduced the problem in Chrome Incognito.The failed delete request returns:HTTP 409errorCode: operationInProgressErrordata: "A conflicting operation is being performed on one or more of the selected items."It seems that there is a persistent/stale operation or lock affecting this folder hierarchy. How can I ask for Box to clear it?

Whenever I try to save app configuration in the app portal I get this error. Regardless of what I am changing.{"error":{"code":"Unexpected error"}}Any ideas?
