Synchronous Web Service
A Synchronous web service is used when a client or a calling system is expecting an immediate process response for a process request. The client or a calling system blocks on the called thread and waits until it receives a response or times out. A synchronous web service can be used to retrieve information from a business process. Boomi allows us to expose an existing process as either a SOAP or a RESTful web service.
Building a Simple Hello Synchronous RESTful Web Service.
1. Create sample json request file “hellorequest.json” and response file “helloresponse.json” in a text editor.
Add the following text to the hellorequest.json file
"firstName" : "Smith",
"lastName" : "Jones"

"message" : "Hello Smith Jones! Welcome to the Dell Boomi Platform."

Deploying the Hello web service to a Local Atom in TEST Environment for testing.
1.Please setup a Local Atom in a TEST Environment and verify that it’s is up and running. Please refer to my post on Installing Dell Boomi Local Atom on Windows. on how to setup local atom in TEST Environment.
Navigate to Manage -> Atom Management
Click on local atom that you have created ( Local_Atom_MG is the local atom that I have created for my testing ) and verify that the status of the local atom is online.
2. Open the Hello Process in the process editor and click on View Deployment.
3. Click on Attachments.
4. Select Local-Dev under Unattached Environments and click on to move it under Attached Environments.
5. Click on Deployments.
6. Click on Deploy Latest Revision of Process.
7. A Deployment Confirmation dialog box appears. Enter Initial Version in the Deployment Notes text area and click OK. The service gets deployed to the Local Atom.
The available authentication type options that are available in Boomi are None, Basic, Client Certificate Header, Client Certificate, Custom, and External Provider. We will be using Basic authentication type in our example. Please visit the Authentication types section in the link Shared Web Server panel for more information on Authentication type.
1. Navigate to Manage -> Atom Management -> Local_Atom_MG. Click on Shared Web Server under Settings and Configuration. Select Basic for Authentication Type under Authentication settings. Copy the Base URL to a text editor to be used later in the Http Client connector call.
2. Click on User Management.
3. Click on next to Users to add a new test user account to test Hello service.
4. Enter Username – testuser1. Copy testuser1@xxxxxxxxxxx-XXXX to a text editor to be used later in the Http Client connector call.
