This is expected behavior. My suggestion is to implement it similar to this discussion, but download the file on user request instead automatically.

Using document id stored in database ,Through safe url, i can download files from my on-premise site (that are stored in cloud env). This happens only when i logged in to cloud env also. When I logged out from cloud env, i'm unable to download the document. I get the below error message on a new browser tab:

{"resource":"\/suite\/webapi\/downloadReports\/12229","error":"APNX-1-4187-000","message":"Authentication failed. Please check your credentials and try again.","title":"An Error Has Occurred"}

So, your issue is that your users hav no permission to access the cloud env, right? Then, you could start a process via startProcessLink which the user clicks on. The document is downloaded via in that process and a chained task form shows the download link.

Does that help?

Stefan Helzle Hi Stefan, I have a requirement wherein we have two environments - one on cloud and one on premise and documents are stored in cloud environment. I've stored the document ids in the database. The on-premise users have to download certain files from cloud environment. What is the best way to implement this? I've tried using the document link as web api and downloading it using safe url. but authentication cannot be done in this way. Please suggest some work around

Hi Stefan,

Thank you very much, it worked. I was creating webapi's before from scratch. So I didn't look in the coding or templates. Now I think I can migrate the document as per my plan.

You might want to change this line in your API.

local!extensionWhitelist: {"pdf", "txt", "png", "jpg", "jpeg"},

Hi Stefan,

I have folders like "Test PDF files", "Test Image Files", and "Test Word Files" in "Test Knowledge Center". All the folders are inheriting the security of "Test KC". So, the security is same for all the folders and the user has editor access to all folders. But I can move the pdf files and images files, but not the word files. I even tried moving the word file to PDF Files folder. Even then I am not able to download. I am not able to figure out the issue. Have you tried moving the word files using web api? Any suggestions would be of great help.

This is not a file type issue. Are the word files in another folder inside Appian? Does the user doing the calls have permission to this folder?

Hi Stefan,

I tried your method. It is working fine for image files and PDF documents and saving them to the folder, but when I tried the same for word file (DOCX), it is giving the following error:

The requested URL cannot be found

error-result-guidance

The external system did not find the requested URL or is refusing to allow access HTTP/1.1 404 404

Any suggestions please?

My example uses Google Charts to create QR code images which is actually just downloading a file.

Hi Stephan,

Thanks for your reply. I created the web api. Actually I am using this web api to move the document from one appian environment to other. I am going to build a process model in the target environment, call this web api and save the document in a folder. This web api I have created is downloading the document. How can I save it in a folder using the process model in the target environment? Any suggestions?
