UNIFIED CONNECTIVITY
Connect PSPs through one technical contract.
Add the payment capabilities the business needs without rebuilding the merchant integration for every provider.
When a merchant needs several PSPs, PayStar provides one extensible API contract while preserving the provider-specific evidence required for support, finance and audit.
[01] one integration, multiple provider lifecycles
One integration, multiple provider lifecycles
Required payment operations
Implement documented deposits, payouts, status checks and balance queries through a consistent merchant-facing contract.
Normalized without hiding the source
Use consistent statuses and error semantics for automation while retaining original PSP responses for investigation and reconciliation.
Add or replace a route without a new merchant project
Keep the merchant-side contract stable while provider adapters and route availability evolve behind the technical layer.
Understand the contract before development
Review authentication, required fields, amount format, statuses, errors, callbacks and scenario constraints before estimating or implementing the flow.
[02] commercial relationships remain direct
Commercial relationships remain direct
The merchant contracts with each PSP and controls routing policy. PayStar connects and operates the technical lifecycle; the PSP processes and settles under its own agreement.
[03] built for more than the integration team
Built for more than the integration team
Normalized events help BI and operations automate. Raw context helps support investigate. Stable schemas and documented callbacks help developers build and maintain the flow.
