API Fundamentals

APIs are routines that perform predefined tasks. JD Edwards EnterpriseOne APIs make it easier for third-party applications to interact with JD Edwards EnterpriseOne software. These APIs are functions that you can use to manipulate JD Edwards EnterpriseOne data types, provide common functionality, and access the database. Several categories of APIs exist, including the Common Library Routines and JD Edwards EnterpriseOne Database (JDEBASE) APIs.

Programing with APIs is useful for these reasons:

  • No code modifications are required as functionality is upgraded.

  • When a data structure changes, source modifications are minimal to nonexistent.

  • Common functionality is provided through the APIs, and they are less prone to error.

When the code in an API changes, business functions typically only need to be recompiled and relinked.
