Managing Upload Keys ​

Upload Keys are Public ​

Upload keys are safe to use in frontend code and client-side applications. They're designed for temporary image uploads from browsers with origin restrictions for security.

Upload Key Structure ​

Upload keys are used directly in the upload URL path:

javascript
const uploadKey = "upl_abc123def456...";
const response = await fetch(`/api/v1/upload-temporary-image/${uploadKey}`, {
  method: "POST",
  headers: { "X-Original-Filename": file.name },
  body: file,
});

Find Your Upload Keys ​

  1. Go to your project dashboard
  2. Navigate to the "Upload Keys" tab
  3. View all upload keys for the current project
  4. Copy the key you need for your application

Create a New Upload Key ​

  1. In your project dashboard, go to "Upload Keys"
  2. Click "New Upload Key"
  3. Give it a descriptive name (e.g., "Frontend App", "Mobile Upload")
  4. Configure allowed origins for the new key

Configuring Allowed Origins ​

Upload keys use origin restrictions for security:

  1. Find the upload key in your project dashboard
  2. Click "Edit Origins"
  3. Add allowed origins (e.g., https://example.com, http://localhost)
  4. Save the changes

The server validates the Origin header against these origins on each upload.

See Allowed origins for more information.

Configuring Temporary Image Expiry Time ​

Under project settings, you can configure the amount of hours temporary images are stored for.
