PhonePe Checkout API

openapi: 3.2.0
info:
  title: PhonePe Payment Gateway Checkout API
  description: 'Server-to-server PhonePe Payment Gateway (PG) REST API for creating

    checkout orders, retrieving order status, and processing refunds across

    UPI, cards, netbanking, and wallets.


    Requests are authenticated with a merchant auth token issued by PhonePe

    and sent in the `Authorization: O-Bearer <merchant-auth-token>` header.

    Partner integrations also include the `X-MERCHANT-ID` header naming the

    end merchant.


    Only a representative subset of the PhonePe PG surface (checkout,

    order status, refund initiation, refund status) is modeled here. See

    the PhonePe developer documentation linked under externalDocs for

    the full catalog.
