Using API Management/Connect with IBM Integration Bus
Different use cases
1. Expose REST APIs from IIB
2. Expose Integration Services from IIB
3. Use Interaction APIs to combine System APIs
10
Expose a REST API from IBM Integration Bus
• Introducing IIB’s new REST API first class construct
• Provides a simple way to receive JSON / HTTP and expose a REST API
• Import Swagger 2.0 definitions, clients can use existing Swagger tools and projects to retrieve Swagger definitions
• Create a new REST API in the IIB Toolkit without having to import a Swagger file (beta)
• Administer REST APIs as a first class IIB construct in the Web UI
11
Simple workflow to implement an API in IIB
1. Import swagger definition into Toolkit 2. Select operation to implement3. Complete the generated skeleton with standard IIB development
tools4. Unit test with integrated runtime5. Package & Deploy6. Push to API Management
• Wizard driven• Import Swagger definition• Select resources and operations
Workflow steps (1)
• Select operations to implement• Add error and timeout handling
Workflow steps (2)
• Add implementation for operation using standard IIB Development tools
• Unit test in integrated Test Node
Workflow steps (3 - 4)
Workflow steps (5)
• REST APIs can be deployed to an integration server using any of the standard mechanisms – either the Integration Toolkit, the command line, or the Integration Java API.
• Once deployed, a REST API appears in the Integration Toolkit and web administration interface as a REST API, under a new REST APIs category.
16
Easy Integration with IBM API Management
• Deployed IIB REST APIs can be pushed to API Management from the IIB Toolkit
• In IBM APIM, begin by ensuring you have:– A registered organization and email address for the API owner for
logging in to the IBM API Management console
– A sandbox environment defined, and network connectivity
• The IIB REST API is identified by the API Management server using the Swagger Title
– REST API is created if it is a new definition
– If it already exists, then the latest revision
is replaced
17
Workflow steps (6)
18
Expose existing IIB Integration Service
19
Integration Services•First class IIB construct for Web Services•Consistent representation in Toolkit and WebUI•Imports/Creates WSDL
Simple workflow to proxy a SOAP (Integration) Service
1. Create API in API Management• Import WSDL
2. Configure API• Description• Security• Properties• Implementation
3. Create Plan• Define SLA• Add API operations
4. Publish

Summary
Services or APIs? – Services with APIs
Services APIs
Business function, coarse grained, discrete task in a process
Business resource, atomic, simple, cacheable
Share business capability across the enterprise Extend functionality, crowdsourcing
Integration between heterogeneous applications Consumable by heterogeneous clients
Share and reuse assets in enterprise Grow ecosystem with maximum reach, maximum access,
Consolidate redundant functionality Enable functionality to evolve
Adhere to common enterprise standards Flexible, low barrier of entry, lightweight
Enterprise /inter-enterprise domain Extra enterprise, Internet of Things
Implementation focus Interface focus
Provider focus Consumer focus
Similar distinction between System APIs vs Interaction APIs
Already Have APIs?
Companies already have web services, which can be exposed as APIs
Software vendors are adding API support to existing products to pass through data from a system of record unchanged; aka System APIs
System API System API

Added Management & Security to protect enterprise assets
System APIs should be managed and secured to protect enterprise systems:
Where are they published? Which developers can discover them? Which applications can access them? How frequently? At what cost?
