Publish title and body templates

Render notification title and body from versioned templates, with optional image, data, and deep-link fields.

Set Android message expiry

Configure the Android TTL field in your push content. Device permissions, connectivity, and platform behavior affect delivery.

Push uses the background notification pipeline, including retry handling, circuit breaking, and recorded delivery failures.
