24. Connectors
● A connector is a ready made and convenient tool
to reach publicly available Web API’s.

25. Connectors
● Connectors allow rapid and easy integration of
different APIs to meet business needs.
● ESB 4.8.0 introduces the first five connectors:
○ SalesForce
○ Google Documents
○ Twilio
○ Twitter
○ JIRA
● Many more connectors coming soon!

26. Sample Connector Use Case
● Opportunity Management: SalesForce + Google
SpreadSheet

27. Sample Connector Config
● Searching for tweets.
● Basic flow:
○ init operation - can be stored as local entry.
○ Connector operation.

28. Connector Tooling
● Dynamic tooling support with Dev Studio

29. Connectors
● Connector Architecture
○ Based on Synapse Templates and Mediation
Library
○ Diverse API’s (REST, SOAP, SDK)
○ Tooling with Dev Studio
● Connectors hosted on GitHub:
○ https://github.com/wso2/esb-connectors/
● Anyone can create and share their own connector

30. Message Store/Processor Improvements
● Stabilization of MSMP to cater guaranteed
delivery and rate matching scenarios.
● RESTful message support with guaranteed
delivery.
● Message Forwarding Processor now supports
multiple endpoint.
● Message processors now persist
active/inactive state.

31. Message Store/Processor Improvements
● Forwarding Processor
○ Separate intervals for message
consumption and retrying messages.
● Multiple message processors per message
store
● Support for applying security policies to
incoming and outgoing messages.

32. JSON Improvements

Log mediators.
● Payload Factory supports mixing XPath and JSON
Path.

33. New Mediator: Call
● Call Mediator
○ Changes the way we think of service
orchestration.

HTTP.
○ Calls backend service and on response,
continues mediation flow following call
mediator.
○ More intuitive service chaining.

34. New Mediators: Respond & Loopback
● Two mediators useful during development and
testing.
● Respond
○ Immediate response to client sending current
message in Message Context.
● Loopback
○ Move mediation flow to beginning of out flow.
