payment-integration

Multi-provider payment orchestration centralizes checkout, webhooks, and subscriptions across Stripe, Polar, Paddle, SePay, and Creem.io from a single integration. It uses deterministic scripts and idempotent webhooks to unify provider workflows for SaaS and licensing scenarios.

Managing idempotent webhooks ensures automated benefit delivery processes each subscription event exactly once. This approach applies deterministic verification scripts and audit-ready metadata to synchronize subscription states and licensing across multiple payment providers.

This payment integration supports tax compliance and currency handling for global SaaS deployments. It orchestrates Merchant of Record providers like Paddle and Polar alongside direct processors like Stripe to manage regional tax calculations and multi-currency checkout flows.

QR code payments and revenue sharing workflows are supported through SePay and Creem.io integration. The orchestration handles QR-based checkout flows and automates revenue splitting across providers using audit-ready metadata and deterministic scripts.

Implementing licensing workflows requires deterministic verification scripts to validate entitlements across multi-provider payments. The integration applies progressive-disclosure references to guide setup, ensuring licensing remains synchronized with subscription and checkout events across all providers.

Unifying checkout and webhooks across multiple payment providers requires maintaining idempotent webhook handlers and audit-ready metadata for each provider's specific API constraints. Complex edge cases in revenue sharing and currency handling may demand provider-specific logic outside the centralized orchestration.
