Fintech firm Razorpay has become the first Indian payments company to integrate directly with OpenAI Codex. "A developer prompts 'build me a fitness app with a ₹499 one-time payment.' Codex builds it. Razorpay handles the payments...No separate integration," Founder Shashank Kumar said. This move will allow developers using Codex to connect Razorpay within the agent and accept payments.
