Paypay SDK - PHP

PHP Class for interacting with the Paypay API This is the quickest way to integrate PayPay payment services, primarily meant for merchants who wish to perform interactions with the Paypay API programatically. With PayPay's OPA SDK, you can build a custom payment checkout process to suit your unique business needs and branding guidelines.

Integrating with PayPay's Open Payment API (OPA)

Prerequisites

Before integrating with the SDK, run through this checklist:

• Understand the payment flow
• Sign up for a PayPay developer/merchant account
• Generate the API keys from the Developer Panel. Use the sandbox API keys to test out the integration

Minimum required software requirements

To use the Paypay OPA PHP SDK you need:

• A server compute environment (local machines, docker containers, VPS or dedicated servers, cloud infrastructure etc. )
• A web server to serve your API responses and html documents.
• PHP version 7.x interpreter to execute your backend code.
• Composer to manage your dependencies(recommended) or a release version from this repo to manually maintain your dependencies.

HMAC Signature Verification

Signature verification is a mandatory step to ensure that the callback is sent by PayPay and the payment is received from an authentic source.

Generate a Signature

The PayPay signature, returned to you on successful payment, can be generated by your system and verified as follows:

• Start by hashing the body and content-type with MD5 algorithm
• • Note : If there is no request body, for instance, the HTTP GET method case, no need of generating MD5. Instead hash value is set as "empty".
• The value of authHeader is passed in HttpHeader. AUTHORIZATION. The authHeader will decode back to the data added and with the HTTP request object and based on data available for api-key in the system, we will recreate the SHA256("key", requestParams) which gives macData. This macData is verified against the value passed in the header.
