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. This connectivity layer is the foundation of PayStar Direct Connect.

[01] one integration, multiple provider lifecycles

One integration, multiple provider lifecycles

01

Required payment operations

Implement documented deposits, payouts, status checks and balance queries through a consistent merchant-facing contract.

02

Normalized without hiding the source

Use consistent statuses and error semantics for automation while retaining original PSP responses for investigation and reconciliation.

03

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.

04

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.

[04] plan the next provider connection

Need a provider that is not connected yet?

With Fast-track Integration, agree the adapter scope, fixed development price and delivery window with PayStar. Each order is accepted separately after its readiness and delivery place are confirmed.

For an APM adapter developed to your priorities, explore Self-integration. A dedicated developer implements and maintains the adapter on PayStar infrastructure; we can help you find and prepare the specialist.

Provider approval, available operations and route readiness still need to be confirmed for the merchant's payment flow.
