Integrate Faster with SP Transaction Hub
A developer resource hub for encrypted payment initiation, callbacks, transaction status, refund creation, refund status, sandbox validation, SDK references, API explorer guidance, Postman-ready assets, webhook patterns and production go-live guidance.
Encrypted Merchant Contract
Use the merchantId + encData envelope with AES-256-GCM and SHA-256(apiKey) key derivation.
- AES-256-GCM payload model
- SHA-256(apiKey) derivation
- Production-ready request envelope
SDKs and Starter Assets
Use starter references for checkout, status, refund and webhook integration across merchant engineering workflows.
- Checkout and payment flow references
- Status and refund starter patterns
- Webhook-ready engineering assets
Return URL and Push Webhook
Use browser return for customer experience and push webhook as the server-side signal.
- Customer return-state guidance
- Server-side source-of-truth flow
- Merchant callback planning
API Explorer and Endpoint Coverage
Review payment initiation, transaction status, refund and operational endpoints before implementation starts.
- Payment initiation endpoints
- Refund and status coverage
- Operational API visibility
Security & Compliance
Best practices for PCI alignment, encryption and production hardening.
- PCI-aware handling guidance
- Encryption and transport hygiene
- Go-live hardening checks
DIRECT, REDIRECT and White-Label Flows
Start hosted checkout, route directly, or support white-label merchant journeys with the same integration model.
- Hosted and direct integration patterns
- White-label merchant journeys
- Common rollout decision support
UAT, Sandbox and Production URLs
Test on UAT first, validate integration assets, then switch to the production base URL after go-live approval.
- UAT validation flow
- Sandbox-to-prod handoff
- Go-live environment checklist
Postman Collection and Sample Code
Accelerate integration reviews with reusable request examples, payload samples and endpoint collections.
- Reusable request collections
- Payload and header samples
- Faster developer onboarding
Error Codes and Versioning
Document response patterns, failure handling and version-aware rollout planning before production cutover.
- Response and failure mapping
- Version-aware rollout notes
- Escalation-friendly diagnostics
Status, Refund and Support APIs
Use /transaction/status, /refund/process, and /refund/status for enterprise operations and support workflows.
- Transaction status checks
- Refund initiation coverage
- Support and ops visibility
