ShareX
Windows AvailableShareX is a free, open-source screen capture, file sharing and productivity tool for Windows. XBackBone has first-class support for it: one downloaded file configures ShareX to upload straight to your instance.
Set up
- Sign in to your XBackBone instance.
- Open Integrations from your profile menu.
- On the ShareX card, click Download config to get your personal
.sxcucustom-uploader file. - Double-click the downloaded
.sxcufile to import it — or, in ShareX, go to Destinations → Custom uploader settings → Import → From file. - In ShareX, set XBackBone as the active uploader under Destinations.
That's it. Capture a screenshot or drag a file onto ShareX and it uploads to your instance, copying the share link straight to your clipboard.
What the config contains
The generated .sxcu is a standard ShareX custom uploader, pre-filled with your instance URL and a personal API token. It targets the /api/v1/upload endpoint and is wired up as your image, text and file uploader as well as a URL shortener / sharing service, so every ShareX destination type flows through XBackBone.
On download, XBackBone mints a token granted the resource:upload and resource:deleteabilities — enough to upload new resources and remove ones you created (ShareX exposes the latter through its per-upload deletion URL).
Keep your token safe
The .sxcu file embeds an API token in plain text. Treat it like a password. If it leaks, revoke the token from Profile → Tokens and download a fresh config.
Troubleshooting
- Uploads fail with a 401 / "Unauthenticated". The embedded token was revoked or the config is stale — download a fresh
.sxcufrom Integrations and re-import it. - The wrong destination is used. Make sure XBackBone is selected as the active uploader for the relevant type under Destinations.
- Links point to the wrong host. Re-download the config after changing your instance's
APP_URL; the URL is baked into the uploader at generation time.
