API for BOX version overwrite uploads

Hi 

You can use this API https://developer.box.com/reference/post-files-id-content/ to upload a new version. You need to know the fileID of the existing version

Thank you for sharing your knowledge.
I tried to implement it with your reference, but the version was updated, but at the same time the contents of the file disappeared.
I am not sure what is causing this.

Not sure what you mean by the contents of the file 'disappeared'?

If you use this API https://developer.box.com/reference/get-files-id-versions/ you should see a list of all file versions and their sizes. If you successfully uploaded a new version with a non-zero byte size it should show in the list

Rgds,

I checked the version of the target file from a web browser, and V1 was uploaded successfully after referring to the following URL.
https://ja.developer.box.com/reference/post-files-content/

However, for V2 and later, I tried using the following URL that you shared, but the byte size became 0 and the contents of the file disappeared.
https://developer.box.com/reference/post-files-id-content/

Sounds like you are uploading a zero byte file?

This is how I did it in postman
Upload file

Upload new version using the ID from above

Result with size (I uploaded same file)

From Box UI

Thanks for the advice.
I reviewed it and it works.
I apologize for the inconvenience.
