SIHOT.PAYENGINE – API Developer Documentation

Welcome to SIHOT.PAYENGINE! This portal will guide you through every step of integrating secure, PCI-compliant payments for your SIHOT applications.

What is SIHOT.PAYENGINE?

SIHOT.PAYENGINE is a middleware service that acts as a unified interface between the SIHOT product suite and a wide range of Payment Service Providers (PSPs). Its core purpose is to abstract and centralize payment and tokenization processes, allowing seamless integration of all SIHOT modules and third-party applications without requiring direct PSP integration in each product.

Purpose

The primary goal of SIHOT.PAYENGINE is to standardize payment processing across all SIHOT and partner applications. By offering a consistent API that mirrors common payment interface structures, SIHOT.PAYENGINE enables:

  • Tokenization of payment methods
  • Payment authorization and capture
  • Refund handling
  • Seamless referencing of payment transactions within various business contexts (e.g., bookings, receipts)

This approach eliminates the need for repetitive, product-specific payment logic and ensures consistency across systems.

Key Benefits

  • One API – Multiple Providers: Partners benefit from immediate access to all PSPs already integrated with SIHOT (e.g., Adyen, Stripe, PayPal, Concardis, etc.), without additional development efforts.
  • No Product-Level Adaptation Required: Payments can be triggered from any SIHOT module or partner system without modifying the internal payment handling of those systems.
  • Cross-Workflow Compatibility: Tokenized payment data can be transferred between applications (e.g., from a booking engine to PMS) to support scenarios like reservation guarantees or final payment references.
  • Secure & Scalable: Tokenization and payment processing are handled in a PCI-DSS-compliant environment, reducing exposure to sensitive card data.

Partner Responsibilities

Partners integrating with SIHOT.PAYENGINE are expected to:

  • Use the provided API to initiate and manage payment transactions.
  • Decide how to handle the results of those transactions in their own systems.
  • Where applicable, pass tokenized payment information to other SIHOT products using their respective APIs.
  • Ensure their systems align with the use cases supported by SIHOT (e.g., pre-authorization for booking guarantees, final charges at checkout, etc.).

Integration with SIHOT.PAYENGINE empowers partners to participate in a comprehensive and future-proof payment ecosystem, designed for the needs of modern hospitality operations.
