IBM Business Process Manager programming
You can find programming guides and examples for programming various IBM® BPM components, applications, and services, in this section.
For details of the application programming interfaces (APIs) and system programming interfaces (SPIs), see IBM Business Process Manager API reference.
- IBM Business Process Manager REST API programming
IBM BPM provides several sets of REST APIs for programming components, applications, and services. - IBM BPM JavaScript API programming guide
In Process Designer all variables are JavaScript variables so you can use JavaScript code snippets inside your components to improve the behavior of your model. - IBM BPM web service APIs programming guide
The application programming interface (API) for web service clients defines a number of schemas and provides a set of operations to access Process Designer functionality from an external client application. 
Programming BPEL processes and tasks
You can use a modeling tool to build and deploy BPEL processes and tasks in IBM BPM. These processes and tasks are interacted with at run time, for example, a process is started, or tasks are claimed and completed. You can use Business Process Choreographer Explorer to interact with processes and tasks, or the Business Process Choreographer APIs to develop customized clients for these interactions.- Enterprise Service Bus programming
This development guide is for enterprise architects, integration architects and developers who are responsible for implementing integration and connectivity solutions. It begins with the high-level concepts and abilities that will help you to understand the capabilities and usage patterns of an Enterprise Service Bus (ESB). The development guide then describes how to implement the capabilities and patterns on IBM Process Server. - Service Component Architecture programming
Service Component Architecture (SCA) provides a simple, yet powerful programming model for constructing applications based on service-oriented architecture (SOA). - Business objects programming
Business objects are containers for application data, such as a customer or an invoice. Data is exchanged between components by way of business objects. - Business rule management programming
Public business rule management classes are provided for the building of custom management clients or to automate changes to business rules.
