💳 Payment Integration Details

For Indian payment methods (PhonePe/Bank payments), I need to know:

1. Payment Gateway Choice: a. Razorpay (supports UPI, PhonePe, Net Banking, Cards - most popular in India, easy integration) b. PhonePe Payment Gateway (official PhonePe for Business integration) c. Paytm Payment Gateway (supports all Indian payment methods) d. Cashfree (supports UPI and other Indian methods)

2. API Keys:

Do you have a payment gateway account already? If yes, which one?

Can you provide the API keys (Key ID, Secret Key)?

OR should I set up test/sandbox mode first for demo purposes?

Recommendation: I suggest Razorpay as it's the most developer-friendly option for Indian payments, supports PhonePe/UPI/Net Banking/Cards, and has excellent documentation. You can start with test mode (no real money) and upgrade to live mode later.

3. OTP Integration:

For OTP authentication, which service should I use? a. Twilio (paid, international) b. MSG91 (Indian, affordable) c. Firebase Phone Auth (Google-based, free tier available) d. Mock OTP for now (for testing, implement real OTP later)
