Leveraging the Twitter Adapter in ICS – Tweeting through Oracle Integration Cloud Service by Lucas Jellema

The Oracle Integration Cloud Service – ICS – comes loaded with a rich collection of Cloud Adapters. These adapters facilitate the integration with SaaS applications and internet services of various natures. These include Oracle SaaS applications (such as RightNow, Eloqua, ECommerce Cloud, ERP Cloud, HCM Cloud), on premises ERP applications (SAP, EBusiness Suite, Siebel) and assorted third party applications such as SalesForce, Facebook, Google Mail and Task, LinkedIn and Evernote. Through these adapters, interacting with said applications and services becomes a simple, declarative operation instead of a custom programming effort.

In this article, I will use the Twitter Adapter to create a connection to a Twitter Account (leveraging the Twitter API under the covers). The Twitter Adapters exposes over a dozen operations. I will use just the operation to publish a message (aka Tweet) in this example. From ICS, I will expose an integration through a simple REST connection. This allows trusted consumers to publish Tweets in a very easy way – leaving the authorization details and the API intricacies to ICS.

The steps I went through:

• Grant access to [ICS Connection] app in the Twitter developer page and generate API Key and Consumer Key
• Create a new ICS Connection based on Twitter Adapter; set up the API Key and Consumer Key
• Create an ICS REST Connection (to expose)
• Create an integration – between REST Connection as inbound (source) to Twitter Connection (as outbound destination); configure the endpoint (inbound) and operation (inbound and outbound)
• Create the mappings for request and response
• Define the tracking – business identifiers
• Activate the integration
• Test the exposed REST connection from any REST client, for example SoapUI, to Tweet a message through a simple REST POST call

Most of these steps are explained by the screenshots you will find below. Read the complete article here.

Create an Integration on ICS to expose a REST API for a SOAP Connection for an external web service by Lucas Jellema

In this article, I will show a little bit more of ICS – the Integration Cloud Service. In a previous article, I have introduced some concepts – such as Connection, Integration, Business Identifier. I have shown how to create an integration connecting two connections – an inbound and an outbound one (both of type SOAP).

In picture, that looks like this:

In this article, I will create a new connection (REST API style) and create an integration to expose this connection, leveraging the same outbound connection:

After creating the integration, I will activate it and invoke the new REST API from a web browser and from SOAP UI.

The steps are:

• Create REST Connection
• Create and activate the Integration (with the mappings for request and response and the business identifiers for tracking)
• Invoke the REST API

Configure REST Connection

Go to the ICS Home Page and navigate to the Connections page.

Create a New Connection. Read the complete article here.

The quick introduction to the Integration Cloud Service (Oracle PaaS– ICS) by Lucas Jellema

Integration is the term we employ for ‘what ties systems together into end-to-end interaction flows’. Integration describes what we have to do to make applications in one domain talk to those in another, or systems in one enterprise talk to those in another. And to systems running in one cloud interact with those running in another cloud or those running on premises. Integration is ideally approached based on standard based service interfaces and encapsulated implementations. With generic integration facilities handling most of the protocol, format, and technology specific details, and translating interactions as much as possible to standard SOAP and REST exchanges. And with that generic platform handling monitoring, security, system errors and state when asynchronous exchanges are required.

The Oracle Integration Cloud Service (ICS from now on) provides the cloud based integration platform that can run and manage these integration flows. ICS exposes a browser based user interface through which the integration is first designed, then activated and managed. ICS provides adapters to easily interact with a number of popular SaaS applications (Salesforce, Oracle HCM Cloud, Oracle ERP Cloud, Oracle SalesCloud, Service Cloud | Right Now, Eloqua, CPQ, Gmail & Google Task, Evernote, …) and Platform Services and technologies (Oracle Database, Oracle Messaging Cloud Service, FTP, SOAP and REST services) as well as a collection of Social Networks (Twitter, Linked In, Facebook). With ICS it is straightforward to connect to any of these as a target and expose an tailor made, easy to use interface to ICS consumers. Some of these can also be a source for interactions: events in SaaS applications  – such as creation or update of a business object – can trigger ICS to perform an integration flow – pushing data derived from the event to some target.

In this article I will introduce some of the core terminology for ICS and demonstrate my first steps. I will create a SOAP service that exposes a simple operation to convert distances in meters to their equivalent in yards. This service is the based on an existing conversion service offered by a third party. ICS is used to virtualize this service and map to and from between the business friendly interface that I have devised and the pre-existing service interface.

Overview

You will see how I have to first create two connections. Connection is the ICS term for an external link – either outbound from ICS to target systems  (comparable to business services in Service Bus or a Reference in SCA composites) or inbound into ICS (from external consumers), similar to Proxy Service in Service Bus and Service in SCA composites. One connection is outbound, to the third party service that does distance conversions. The other connection is inbound – it describes the SOAP interface that I want to expose from ICS to my consumers. Read the complete article here.
