Sage Integration Methodology

    How to integrate with Sage's diverse product line — Sage 50, Sage 100, Sage Intacct, and Sage X3 — using the right API or SDK for each.

    Sage Intacct
    Sage 50 SDK
    Web Services
    OAuth

    Sage Intacct: Modern Cloud API

    Sage Intacct uses an XML/REST Web Services API with OAuth authentication and Sender/Session credentials. It's the right Sage product for cloud-native integration projects and multi-entity consolidation.

    • Sender ID + Session ID authentication pattern
    • Dimension-aware data model (entity, location, class, project, etc.)
    • Web Services rate limits and concurrent-session governance
    • Smart Events and outbound HTTP for webhook-style triggers

    Sage 50: Legacy SDK Patterns

    Sage 50 uses a Windows COM-based SDK backed by a Pervasive database. Integrations require code running on the same machine or remote-desktop access to the server.

    • Use 'using' statements in .NET to ensure connection disposal
    • Add retry logic with exponential backoff (2s, 4s, 8s) for record-locked errors
    • Implement a queue for write operations during business hours
    • Migrate to Sage 50c cloud or Sage Intacct when integration needs outgrow SDK

    Sage 100 & Sage X3

    Sage 100 supports both an REST/eBusiness API and the Business Object Interface (BOI) for deeper customization. Sage X3 exposes Web Services and 4GL Adonix code for enterprise-grade integration.

    • Sage 100 BOI for write operations not supported by REST
    • Sage X3 Web Services with Java pool tuning for throughput
    • Per-environment credential isolation
