Design and Deploy Your First Integration Flow

Click on the URL in the integration capability. Click the Design tab (pencil icon) to access your workspace. This is where you will create your integration package and integration flow.

This is the space where you will work on your integration flows and where you can access all your integration projects.

1. Choose Create to create a new integration package.

   An integration flow should be associated with an integration package.

   

   In the Header tab, provide a Name and Short Description for your integration package.

   The Technical Name gets populated automatically based on the name that you provide.

   Choose Save and then choose Artifacts to navigate to the artifacts tab. In this tab, you will create your first integration flow.

   

2. Choose Add > Integration Flow.

   

   Enter a Name for the integration flow and choose OK.

   

3. Save the integration package by choosing Save and open the integration flow by selecting it.

   You can then edit the integration flow to add the required steps to create your integration scenario.

   

1. Access your integration package by choosing Design > (Integration package name).

2. Access your integration flow by choosing Artifacts > (Integration flow name).

3. Start editing the integration flow by choosing Edit.

   

1. Create the sender channel by clicking the arrow icon on Sender and dragging it to the Start Message step.

   

2. In the Adapter Type prompt, select the HTTPS adapter.

   

3. Select the Connection tab. In the Address field, enter /products/details.

   Optionally, you can enter any value of your choice, but ensure that you use “/” symbol before specifying the endpoint name. Deselect the CSRF Protected checkbox (this will be selected by default).

   

1. From the palette (the grey bar on the top containing integration flow steps), choose Message Transformers > Converter > JSON to XML Converter.

   You add this converter because the input to the integration flow is sent in JSON format. After the input is converted into XML, the message is sent as header information to the OData service to fetch the required product details.

2. Connect the converter to the message path by clicking on the message path.

   TIP: When you place your cursor on the message processing path, you see it change to green color.

   

1. Choose Message Transformers > Content Modifier and add it to the message path, as you did for the JSON to XML Converter.

   

2. Configure the Content Modifier by selecting Message Header > Add and entering the following parameters:

   Field Name	Description
   Name	productIdentifier
   Type	Select XPath from the dropdown list
   Data Type	java.lang.String
   Value	//productIdentifier

   

From the palette, choose Call > External Call > Request Reply. Connect it to the message path, similar to the previous steps.

1. Move the Receiver step below the Request Reply step by selecting it and dragging it to the desired position on the palette. You do this to ensure that your integration flow is elegantly designed.

   TIP: Use the pan and zoom controls (highlighted in yellow) for resizing the canvas. Use the guidelines to ensure that Receiver is aligned with the Request Reply step.

   

2. Connect the Request Reply to Receiver by dragging the arrow icon on Request Reply to the Receiver.

   

3. In the Adapter Type prompt, select OData. In the Message Protocol prompt, select OData V2.

   

4. Select the Connection tab. In the Address field, enter https://refapp-espm-ui-cf.cfapps.eu10.hana.ondemand.com/espm-cloud-web/espm.svc. This is the URL of the online web shop from which you will fetch the product details.

   

5. Select the Processing tab and choose Select in the Resource Path field.

   

6. Ensure the connection details are the same and choose Step 2.

   

7. Click the Select Entity field and choose Products from the dropdown list.

   

8. Enable the Select All Fields checkbox and choose Step 3.

   

9. Choose the Select Field icon.

   

10. Select Product ID and choose OK.

    

11. In the dropdown list, select Equal. In the value field, enter ${header.productIdentifier}. Choose Finish.

    

Now you have configured the OData adapter to fetch the details of the product based on the product ID that you send as input while making the HTTP call.

1. Choose Deploy to deploy the integration flow. Choose Yes in the confirmation dialog for deployment. Once you see the deployment confirmation, choose the Operations View tab to access the monitoring view.

   

2. In the Monitor view, under the Manage Integration Content section, choose All to access all the artifacts that you have deployed. You will also see the integration flow that you have deployed here.

   

3. Please wait till the integration flow is in status Started. Then, select the integration flow and in the Endpoints tab, choose the Copy icon.

   

   You will use this endpoint in a subsequent step. You define the integration flow endpoint as application programming interface (API). You can, finally, call the integration flow API using API Management.
