Web Services architecture utilizes:
P21 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 2015, Grey Wolf started the development of P21 APIs for integration with the Prophet 21 system. Over time, those APIs have grown and matured into over 70 APIs in the “pool.”
Prophet 21 in an on-premise environment allows Grey Wolf to install our own APIs to create the integration.
The customer installable download puts a small set of files on the P21 server (or another server with SQL access) that the Grey Wolf web services will communicate with 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 P21 system with access to that software from the Grey Wolf Web Services server in our secure datacenter.
The APIs are customer installable and load just a few files either on your P21 server or another server that has access to the P21 server.
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.
