M419: Starting Automatically when Cross-Domain Communication is Received

 

For automating inquiry handling or brochure request handling there are methods of automatically starting a Case that can be used, triggered by a notification email from a web server or iframe embedding on a website. If more complex handling is required consider triggering the [Message Start Event (HTTP)] with CORS AJAX communication.

1. Advantages of CORS Start

a. From the aspect of eliminating emails (compared to email notification)

Direct storage in each Data Item, avoiding email delay, etc.

b. From the aspect of eliminating iframe (compared with iframe embedding)

Design uniformity, dynamic displaying according to the browser setting of the user, etc.

• Compared to notification email (M218) and iframe embedding (M220 / M222) the technical requirement level is higher

2. Overview of CORS Technology

a. Confirmation of Cross-Origin Resource Sharing (CORS) Specification

Mechanism of client-side Cross-Origin requests (W3C)

b. Learn how to implement JavaScript

MDN web docs or jQuery API etc.

3. Permit CORS Communication (System Administrator authority)

1. Enable throughout the Workflow Platform

Becomes capable of receiving CORS communication.

2. Register the permitted server URLs

URL of the company's own website, etc.

3. Make a Start Event in a Workflow App

Place a [Message Start Event (HTTP)] at the beginning of the flow (M221)

System Settings – CORS

• In cases where the page is public the app key will be publicly visible. If necessary, construct a mechanism to eliminate spam in downstream of the Workflow.

4. Monitor CORS Communication

a. Check the Message Start Event (HTTP) summary

Public node list in administrative menu [App External Connectivity]

b. Filtered display of all Cases (System Administrator authority)

Narrow down the display at the administrative menu [Case log] (M313)

• Normal users with the App privilege [Data Viewer] authority can also filter and display all Cases（M117）
