Streamlit is brilliant for rapid deployment, but it doesn’t have native checkout carts or user login systems built-in.
i cant get payment gateway approvals easily and how to instill UPI on my web apps .
so whats the solution.
Hey, thanks for your thoughtful question! You’re right—Streamlit doesn’t natively provide checkout carts or payment gateway integrations like UPI out of the box. For user authentication, Streamlit now supports OpenID Connect (OIDC) providers (e.g., Google, Microsoft) using st.login, st.user, and st.logout—but not custom login or payment flows directly. Payment gateways (including UPI) require external integration, typically via third-party APIs or components.
For payments, the community often uses Stripe with custom components or packages like st-paywall for subscriptions, or streamlit_stripe_card for card payments. UPI integration isn’t natively supported; you’d need to use a payment provider (like Razorpay or Paytm) that offers UPI and embed their payment links or APIs in your app, handling callbacks and verifications externally. For authentication, use Streamlit’s OIDC support or third-party components like Streamlit-Authenticator. See Streamlit authentication docs and community payment discussions for more.
