Create outbound integrations

For outbound integrations, you need to create a Lombardi Integration service. Integration services can include either a Web Service Integration component or a Java Integration component. The following table describes how each integration component functions:

Integration component Description See...
Web Service Integration Uses a Simple Object Access Protocol (SOAP) connection to access objects from a web service over the Internet. A Web Service Integration component hides the complexity of the underlying WSDL, SOAP request, and SOAP response and also converts inputs into the appropriate XML and outputs into the appropriate Lombardi variables. Use the Web Service integration component in an Integration service
Java Integration Calls methods from a Java class and interfaces with most third-party Java APIs, thus supporting a variety of integration scenarios. Use the Java Integration component in an Integration service

When integrating with an external database, you can use the out-of-the-box Lombardi SQL Integration services available in the Lombardi System Data Toolkit. See Use Lombardi SQL Integration services to learn how to access these services.

When considering what kind of Integration component to use for outbound integrations, think about the available integration methods and protocols. SOAP integrations tend to be very easy to build and are extremely useful, especially if you are not passing volumes of information. Java integrations give you access to the features of the Java language, including published Java libraries and APIs.


Use the Web Service integration component in an Integration service

You should build an Integration service when you want to integrate with an external system to retrieve, update, or insert data in order to complete a task (i.e., outbound integration).

Integration services enable outbound integration

If the implementation for an activity requires that you access objects from a web service over the Internet, you can use the Web Service integration component

Topic Description
Build an Integration service Provides step-by-step procedures for building a sample Integration service that uses an existing Web service; also includes instructions for creating a Human service that implements the Integration service as a nested service.
Understand outbound Web Service security, header, and other options Describes several options that you can specify for Web Service integration components, such as the types of authentication available, as well as helpful reference information.
