Building a custom application to implement an activity (deprecated)

Build a custom application using the IBM® Business Process Manager Web API to implement an activity in a BPD.

If you want to build a custom application to implement an activity within a process, you can use either the IBM Business Process Manager Web APIs or REST APIs to enable your custom application to interact with IBM BPM. For example, the IBM BPM Web API provides operations that enable you to pass variables from an IBM BPM BPD to a custom application and then back to the BPD for continued processing.

To create an external implementation with the REST APIs, these articles are helpful: Using the REST APIs in IBM Business Process Manager and Integrating a business process application with an external system using the REST API.
