Integration Best Practices

1. Verify Signature to Avoid Data Tampering: We recommend this as a Mandatory step to confirm the authenticity of the details returned to you on the return URL for successful payments. Refer to our signature verification documentation to learn more. documentation to learn more.
2. Check Order Status: Use our Get Orders API from the backend to check the order/payment status before providing service to the customers. Refer to our life cycle documentation to learn more about Plural payment statuses.
3. Configure Webhooks: Contact our support team to configure webhook events to avoid callback failures. Refer to our webhook documentation to learn more.
4. Implement Flexible JSON Parsing: We recommend designing your systems to gracefully ignore any additional or unknown fields in the JSON payload during integration.
   • This ensures forward compatibility as our platform evolves or introduces new optional fields.
   • Aligns with industry-standard robust API design principles, preventing integration issues from unexpected data.
     Example: Flexible JSON Handling
   Incoming Request Example

   json  
   {  
     "transactionId": "TXN123456",  
     "amount": 10000,  
     "currency": "INR",  
     "extraField": "IgnoreThisNode"  
   }
   

   Expected Handling: You should process the known fields (transactionId, amount, currency) and gracefully ignore the extraField.
5. Avoid Hardcoding Parameters: To ensure a scalable integration, do not hardcode values such as API keys, environment flags, or identifiers in your system while integrating.
   • Hardcoded values increase the risk of failures when changes occur on the platform.
   • Using configuration files or environment variables makes your integration easier to maintain and adapt across environments (e.g., sandbox vs production).
6. TLS Version: We recommend you to, use "TLS_v_1.2" or the higher TLS versions to avoid any transaction failures.
7. Conduct Sanity Testing: Before fully implementing TLS 1.2 and updating the cipher suites, perform application testing to confirm seamless communication across systems and applications within your environment.
8. Implement Strong Cipher Suites: Configure TLS-enabled services to use only strong cipher suites with robust encryption algorithms and key exchange mechanisms. A list of recommended cipher suites is provided below. All other ciphers should be disabled.

List of accepted Ciphers:

• TLS_AES_128_CCM_8_SHA256

Note:

• You can only test Credit/Debit Cards, Net Banking (via SBI),Cross Border & Pay by Points on UAT/Staging Environment.
• Production credentials will be shared with you after UAT sign-off, to test all flows in the soft production environment before going live.
• Please share the Return and webhook URL for configuration and whitelisting before going Live.
• For any incremental updates or support related to integration, please contact our Integration Team.
