Each workspace admin can choose how long those links remain valid. ## Configure the validity period 1. Open the workspace settings. 2. Select **Security & data**. 3. Under **External file links**, choose 24 hours, 3 days, 7 days, 14 days, or 30 days, then save. New workspaces use a 24-hour validity period by default. ## Where the policy applies The selected period is used for new uploaded-file links included in: * Form email notifications * CSV exports, including the download link for asynchronous exports * Webhooks, Activepieces, n8n, and Zapier * Slack, Discord, and Telegram notifications * Google Sheets rows Existing links keep their original expiration. Internal dashboard file previews and form assets are not changed by this workspace setting. Choose the shortest period that still fits the recipient's workflow. For example, a team that processes weekend submissions on Monday can select 72 hours so links sent on Friday remain available through Monday.
