BEFORE PRODUCTION

Evaluate locally, then prepare your deployment.

Localhost testing does not require a production license key. Before moving to staging or production, install the appropriate license, configure the upload handler, and check request limits and storage permissions.

Temporary uploads are cleared automatically. Save the files you want to keep in your application's FileUploaded handler.
