data.deepLinkoptionalstringApp deep-link URL opened when the user taps the notification.

Frequently Asked Questions

notification fields (title, body) are rendered automatically by the OS when the app is in the background. data is silently delivered to your app handler without displaying anything. For fully custom notification UI, use data only and handle display in your app code.

Urgent transactional alerts (order shipped): 1-4 hours. Promotional content: 24 hours. Chat messages: 24-48 hours. Set TTL to 0 for time-sensitive events that are useless if delayed — live auction bids, real-time sports scores.

Request permission only after a user action — never on first page load. Always explain the value before asking. If permission is denied, do not ask again immediately; show an in-app prompt linking to browser settings when the user indicates interest.
