What is QRPH API Integration?

QRPH is the national QR code standard developed to promote interoperability among banks, e-wallets, and payment service providers in the Philippines.

With QRPH, customers can use various banking applications and e-wallets to scan a single QR code and complete payments instantly.

What Does API Integration Do?

An API (Application Programming Interface) allows your website, mobile app, or business system to communicate directly with a payment gateway.

Through QRPH API integration, businesses can:

• Generate dynamic QR codes

• Accept real-time payments

• Receive instant transaction notifications

• Automate reconciliation processes

• Access payment reporting and settlement data

  
  

For example, an online merchant can automatically generate a unique QRPH payment request during checkout, allowing customers to pay instantly using their preferred banking or e-wallet app.

QRPH API Integration Process

The integration process is designed to be straightforward and business-friendly.

1. Merchant Application & Approval: The first step is merchant onboarding.

• Requirements Submission: The merchant submits the necessary business documents and requirements to MPay PH. The process includes:

  
  

  • Business registration verification

  • Compliance review

  • Due diligence checks

  • Risk assessment

    
    

Once all requirements are submitted, the merchant will receive confirmation from MPay.

• Benefits of This Stage

  • Ensures regulatory compliance

  • Protects both merchants and customers

  • Establishes secure payment processing

    
    

2. Issuance of Credentials: After approval, MPay PH provides access to the merchant's payment environment.

• Merchant Access Includes:

  • Merchant Portal access

  • API credentials

  • Technical documentation

    
    

• Credentials Provided

  • Merchant ID

  • API Key

    
    

These credentials allow developers to securely connect their applications to MPay's QRPH payment infrastructure.

3. Validation & Technical Support: This stage ensures that the integration works correctly before testing begins.

• What Happens During Validation: MPay PH's Technical and Integration Team validates:

  • API requests

  • API responses

  • Parameter mapping

  • Authentication setup

  • Error handling

    
    

If any issues arise, the team assists in resolving:

• Failed API calls

• Incorrect parameters

• Authentication errors

• Data mismatches

• Documentation Support: Merchants receive:

  • REST API documentation

  • Sample API requests

  • Response examples

  • Integration guides

    
    

This significantly reduces development time and improves implementation accuracy.

4. User Acceptance Testing (UAT): Before launching to production, merchants conduct comprehensive testing.

• UAT Scenarios: Developers and business teams verify:

  • Successful Transaction: Customers complete payments successfully and transaction statuses update correctly.

  • Failed Transaction: The system properly handles failed or cancelled payments.

  • Refund Scenario: Refund workflows are tested to ensure smooth customer service operations.

  • Settlement Reporting: Transaction reports and settlement records are verified for accuracy.

    
    

• Why UAT Matters: Testing helps identify issues before real customers begin using the payment system. As a result, businesses can launch with confidence and minimize operational risks.

5. Go-Live Deployment: After successful UAT completion, merchants are ready for deployment.

• Simplified Go-Live Process: One major advantage of MPay PH's QRPH API is the use of a single set of credentials for both Sandbox and Production environments. This means merchants do not need to perform another integration when moving to production.

• Deployment Steps

  • Complete UAT testing

  • Submit Go-Live application through the Merchant Portal

  • Receive approval from MPay PH

  • Merchant account is activated in Production

  • Begin accepting real customer payments

    
    

This streamlined approach significantly reduces deployment time and complexity.

6. Monitoring & Maintenance: Integration does not end after deployment.

• Merchants can monitor:

  • Transaction history

  • Payment status

  • Settlement reports

  • Reconciliation records

  
  

Through the Merchant Portal, businesses gain visibility into their payment operations.

• Continuous Support: MPay PH continues providing support for:

  • Platform updates

  • System scaling

  • API enhancements

  • Technical troubleshooting

    
    

This ensures businesses remain operational as transaction volumes grow.

• Benefits of QRPH API Integration for Businesses: Implementing QRPH can deliver immediate operational advantages.

• Faster Payment Collection: Customers can pay instantly using supported banking and e-wallet applications.

• Improved Customer Experience: A simple scan-and-pay process reduces checkout friction.

• Reduced Manual Processing: Automated payment verification eliminates the need for manual confirmation.

• Better Reporting: Businesses gain access to real-time transaction data and settlement reporting.

• Scalable Payment Infrastructure: As transaction volumes increase, the payment system grows alongside the business.

By partnering with MPay PH, businesses can simplify the entire integration journey, from merchant onboarding and API implementation to testing, deployment, and ongoing support.
