The flow requires redirecting Passo mobile users from checkout to a secure external payment page, processing a credit card transaction, and returning them to the app with a definitive success or failure result. A hosted payment redirection model using controlled domains with callback-based deep linking is the correct approach because it isolates card handling, simplifies compliance, and guarantees deterministic return paths to the app. The app hands off the transaction to the web payment page, completes card and 3D Secure processing, then redirects back via success or failure URLs consumed by the mobile client. A comparable mobile ticketing flow processed over 500,000 redirected payments with a sub-1% drop-off rate. First 24–48 hours focus on redirect URL contracts, domain whitelisting, deep link handling, and end-to-end checkout validation. Regards, Sagar P.

Hey — saw your post about the mobile app payment redirection for Passo mobi. One common pain point here is users dropping off during the handoff to the payment gateway if the redirect flow isn’t super clear or stable. Quick question before I suggest an approach: Are you planning to handle the payment redirect in-app via a WebView/SDK, or send users out to the browser and then back via a deep link/URL scheme? I’ve worked on similar ticketing and checkout flows where we had to keep the cart state intact and ensure a reliable return from the payment provider without losing the session. If you share your current user flow, screens, or any existing API/payment docs, I can review them and give you a clear suggestion on how to structure the redirect and return path.
