Stripe UPI + Wallets Integration

I already accept card payments on my Bubble.io site; now I want to broaden the checkout so visitors can also pay with Stripe UPI first, and then Apple Pay, Google Pay and PayPal.

You will receive my active Stripe account keys, so there is no account setup work—just the technical integration and any configuration changes inside the Stripe dashboard needed to switch on UPI and wallet payments. Recurring billing through Stripe UPI is essential because several subscription-based plans run on the platform.

Once Stripe UPI is live and tested, we can move on to Apple Pay and Google Pay (using the standard Payment Request element or Stripe’s Web SDK) and finally wire up PayPal. Everything must run seamlessly inside the current Bubble workflows and respect my existing data structure, so no hacks or work-arounds that break when Bubble updates.

Deliverables
• Stripe UPI checkout flow supporting one-off and recurring charges
• Updated Bubble workflows and API calls with clean, well-commented logic
• Apple Pay and Google Pay enabled via Stripe in the same unified checkout
• PayPal button added and connected to my PayPal account
• End-to-end testing in both test and live modes, with clear hand-off notes

If you know Bubble’s plugin system, custom API connector, Stripe’s UPE, and PayPal’s JS SDK, this should be straightforward. Let me know your estimated turnaround and any clarification you need, and we can get started right away.
