Use the normal Tringify checkout handoff for PhonePe. The shopper opens the provider’s HTTPS page and returns to the platform URL. A return URL, browser close or provider page message is navigation only. Render the platform’s payment state while Tringify requests the live PhonePe result.
PhonePe Standard Checkout cannot remotely close an order. A cancel operation can still answer paid, and a pending attempt can capture later. The platform decides whether captured money pays the order or is refunded. Themes must not create a separate payment ledger, submit outcomes or show paid merely because the shopper returned.
This uses existing checkout settings in Store Admin and the mobile app. See PhonePe payment integration for provider expiry and refund behavior.
