Hi Box team,I've built a server-side integration that pulls report files from Box folders into an internal TPM dashboard. The app is created and configured, but every token request is refused because the app has not been authorized for our enterprise. I can't clear this myself — it needs a co-admin action in the Admin Console.What I'm asking for1. Authorize this Custom App by Client ID in Admin Console → Apps → Custom Apps Manager → Add App:   - Client ID: 3hmb65ju4kleaytjogzilts6d6azr6tt   - App type: Custom App, Server Authentication (Client Credentials Grant)   - Access level: App Access Only (service account)   - Scopes needed: read-only — read files and folders. Please do not grant write scope.2. Confirm the Enterprise ID I'm using is correct: 1035202.3. Confirm our policy on shared links (see question below).

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?  

Hi Box Support —On Platform App Nautix Website (Client ID niov6aolqdxy9zvlsa61iorwvt, Enterprise [removed by moderator] ), clicking Fetch Client Secret redirects to a 404 (“Oops! We can't seem to find the page”). I cannot retrieve the client secret for Client Credentials Grant. Developer Token still works. Please reset/regenerate the client secret or fix Fetch Secret for this app.

As the developer of voidtools - Everything, I would like to know why the process Everything.exe is blocked from indexing the box folder. If I rename my process, indexing works fine.

Hello, I created an App to help generate an API Key for use in some automation I need to complete. It has been in “Pending Enablement” for a while and I want to ask for support to get this approved. Can someone please help with getting this approved?

Is there an integration with Hazel/Altruist in the works?

when I try to click "fetch secret" button within an app, it shows an info message: "this action requires 2-step verification. please wait while you are redirected."    And after that an empty page shows up.  The thing is the 2-step verification is already set up in my account.  Could you please help with this? What am I missing? 

I'm trying to build an automation between Annature and Box. We use Box as a document management system and Annature as e-signing software. I would really like to automate when a document is signed in Annature, have it push back through into Box and stay down to the correct client folder. Just noting that we have Zapier set up but I'm just struggling to dot the i's and cross the t's and get it fully over the line. If anyone's got any experience in this, I'd love to hear from you. 

Hi,I have a service account that was invited into a few client’s folders. It was probably renamed and it is under developers console → Platform Apps → Name of app now. I got everything here as Authorized and enabled since Jan 2023. Client changed security and enforces 2FA now, which I do have for my account. If I go to to the Content Manager, I see nothing here. All folders I had access to are gone. From the folder’s perspective I see the automation user as Pending I’m also Co-owner in another folder and I have rights to resend the invitationit says it does sent the email but that email is automatically generated so I assumed it comes to me or ideally all owners of the app as listed here but nope, I didn’t receive anything nor other Admins. How am I supposed to accept the invitation to virtual email that doesn’t exist? My use case is that I want to upload files or create sub-folders in a given folder from our integration application. It is our client’s Box probably as Enterprise and th

I have the exact problem that is discussed here - Transfer owned folders | CommunityThe account that is using OAUTH has all Co-Admin management for user and file access based on what is seen in the Manage Users. And the application appears to have the needed rights. However, when attempting to move the content to an Admin account (which we do within the web portal) a 403 forbidden is received. The process seems to allow the transfer to the OAuth user so member to Co-Admin which doesn’t correlate with the error that is received.  I have not tried transferring ownership of the folder to the admin account that we are using for all the other folder storage but really feel like that is not going to work.  I really wish there was an easier way to do this but if anyone has done this and can validate that it will work, I would appreciate the response.

Hi there, we submitted our app mid July for review and haven't heard back from you. We haven’t heard back from the team after 10 days and reached out to [removed by moderator] but also don’t get a response. Do you have a rough ETA on the review? The app can be previewed here: https://app.box.com/integrations/NepcCkAiWm/i Best,Erhard.

We need to rotate the OAuth client secret for an existing production mobile application while older versions remain installed.Could you clarify:1. Can multiple client secrets remain active during migration?2. Does generating a new secret revoke the existing secret?3. Will existing access and refresh tokens remain valid?4. Can existing refresh tokens be used with the new secret?5. Will users need to authenticate again?6. What zero-downtime migration process do you recommend?7. Does rotation require another application review?8. When is it safe to revoke the previous secret?

I am unable to view option to submit my app for authorization. I am not sure why, please help. I have none of the tabs or options where I am able to submit the app for request.

Hi everyone,I'm trying to automate our document approval process and wanted to see if anyone has implemented something similar.Here's our current workflow: A Word document/template is completed. Depending on the document, different people may need to sign. For example: Sometimes A, B, and C Sometimes A, D, and E Sometimes B, C, and F I receive the document and manually create a Box Sign request. I manually add each signer. I manually create every signature field and assign it to the correct signer. I send the request. The most time-consuming part is manually determining who needs to sign and then creating all of the signature fields every single time.Ideally, I'd like the process to work like this: The system reads the document (or metadata within the document). It determines which signers are required. It automatically creates the Box Sign request. It assigns the document to the correct signers. It automatically places the required signature fields for

Hello,We have created a Box Sign document template and would like to send it to multiple existing users for signature in an automated way. I am not an admin and have been trying to achieve this using automation tools like Zapier and n8n.Currently, I have a workflow that reads rows from a Google Sheet (containing user email and template ID) and attempts to send a Box Sign request when a new row is added. However, I am encountering permission-related errors (insufficient scope / 403) when calling the Box Sign API.From my understanding, this might be due to missing Box Sign API permissions (e.g., sign_requests.write) or lack of access to Box Sign for my account.Could you please confirm: Do I need admin approval or additional permissions to use the Box Sign API? Is it possible to automate sending Box Sign requests without admin involvement? Are there recommended approaches or tools for this use case (bulk sending via template)? Any guidance would be greatly appreciated.Thank you!

Hi Box Developer Team,We are developing a Node.js-based Box connector and are facing an issue while working with HTML files.We have uploaded an HTML file (for example, myhtml.html) to our Box account. However, we are unable to retrieve its metadata or upload a new version of the file using the Box API. What we have triedRetrieved the File ID from the Box web interface. Generated a valid OAuth 2.0 access token. Called the Get File Metadata endpoint using the official Box API. Tested the same request using the official Box API Swagger / API Explorer. Verified that the File ID and Access Token belong to the same Box account.   Issue The API consistently returns: HTTP 404 Not Found As a result, we are unable to: Retrieve the metadata of the HTML file. Upload a new version of the HTML file. Continue implementing our Box connector.QuestionsDoes Box support HTML (.html) files as regular files for metadata retrieval and version upload? Are there any limitations or special requirements for HTM

Hello. I’m hoping someone can help with this…I am trying to set up an app, to support the migration of some files from Box to a different storage system.I’ve set up the app on the developer console and it is showing as ‘Pending authorisation’, waiting for our admin to approve.But I am the admin and I’ve not received any emails or contact about it.Any advice on how I can get authorised?Thank you!

Hi there! We're hitting a consistent internal_server_error (HTTP 500) when creating a Box Sign request via the API.Setup: JWT Server Authentication app, App + Enterprise Access, "Manage signature requests" scope enabled, "Make API calls using the As-User header" enabled and re-authorized. We're impersonating the human user (ID [removed by moderator] ) who owns the Box Sign template, since our service account can list templates via GET /sign_templates but can't use them directly in POST /sign_requests (a limitation we confirmed with your community team).The problem: Under impersonation, POST /sign_requests takes ~55–60 seconds and then returns internal_server_error. We've reproduced this three times, varying the template and the payload each time, and it doesn't seem related to our request content. Request IDs:0b9355de83cd15cef04504510a7f61465 0a9813c0d687102d871cee0e92f1189ce 0668ad87c76e7d1b208840e67d0c13163 (bare payload, no prefill_tags — most useful for isolating the cause)The tem

I have an Automate workflow with a generate PDF outcome followed by a request signature outcome. I have 3 signers identified and 3 signature tags on the docgen template. When looking at the final PDF, the signatures are identifed as Signature1, Signature2 and Signature3 for the Field Name in the Signature Details. Does anyone know if there is a way to customize the Field Name for each signature? For example, Signature1 is actually the system user, so I would like to identify that as “User Signature” - I have this as text on the docgen template as a workaround, but I am looking for a dynamic solution.

I have an Automate workflow with a generate PDF outcome followed by a request signature outcome. On my docgen template I have the signature tag [[s|1|r:0     ]] and it is in white text color to hide it from showing under the actual signature that is applied to the final PDF. Unfortunately, the tag is also showing when the PDF is converted to text. Anyone know why the signature tag is not being replaced by the signature itself?
