SX APIs and Web Services Overview

Web Services architecture utilizes:


    • Progress App Server
    • Custom Grey Wolf APIs
    • SX.enterprise code

SX APIs are “a set of subroutine definitions, protocols, and tools for building software and applications.” (Wikipedia). Web Services are “a software system designed to support interoperable machine-to-machine interaction over a network.” (W3C). They have even been called Web APIs by some.


In 2005, Grey Wolf started the development of SX APIs for integration with SX.enterprise system. Over time, those APIs have grown and matured into over 150 APIs in the “pool.”


SX.enterprise in an on-premise environment allows Grey Wolf to install our own APIs to create the integration.
The installation of the SX APIs is done by Grey Wolf since they are not customer installable. Grey Wolf will install a set of Progress code on the SX server. After the code is compiled, the Grey Wolf web services will communicate with the SX APIs to make the connections.


The architecture for Grey Wolf’s APIs is consistent across all ERP systems. There is a piece of software loaded on the ERP system with access to that software from the Grey Wolf Web Services server in our secure datacenter.


While there are different APIs for each ERP, the Web Services are standardized across all subscription users. This ensures consistent results from a standard environment. In the case of custom ERP modifications, Grey Wolf is able to create custom APIs that are then isolated from the standard environment. This ensures consistency while supporting unique customer requirements.

Integration touch points include:


    • Application APIs
    • Data APIs
    • Tester for diagnostics
    • Web Service Keys for security
    • Intuitive naming convention
