This blog is the Part 3 of the 5-part blog-series. In this blog, we will introduce SOAP Interfaces which are exposed from SAP Process Orchestration (from 7.40 onwards) (SAP PO) can be exposed as Open APIs and managed through SAP Cloud Platform, API Management. Here with this blog you will be able to connect SAP Cloud Platform, API Management to your backend (SAP PO System) using cloud connector and will be able to manage SOAP Endpoints exposed in SAP PO
With SAP Process Orchestration 7.5 SP00 you can now deploy and run the cloud integration content also on SAP Process Orchestration benefiting from the investment that we do on HCI.

Cloud Connector Overview
The SAP Cloud Platform cloud connector (cloud connector) serves as the link between on-demand applications in SAP Cloud Platform and existing on premise systems. The cloud connector runs as on premise agent in a secured network and acts as a reverse invoke proxy between the on-premise network and SAP Cloud Platform. Due to its reverse invoke support, you don’t need to configure the on-premise firewall to allow external access from the cloud to internal systems
To know more on SAP Cloud Platform, SAP API Management refer
In this blog I have taken an example of my (******) hanatrial account for SAP Cloud Platform, API Management, N75 as a backend(PO) system and an internal tenant for HCI Content.
- You have access to N75 or any of the PO system
- IFLOW with Soap end point should be available on HCI tenant
Let’s get started!
For Downloading and configuring cloud connector refer
Type https://localhost:**** on your browser following screen should come up
Enter User name and password to login as Admin
Click on Add Account to add an account
Fill in the appropriate details as shown below for your account
Here for SAP Cloud Platform, API Management I have taken example of my hanatrial account
Under Account Dashboard; Account should be added
As I have added my hanatrial account as host so my hanatrial account should be added as shown below
Now we will be adding the On Prem system for eg N75 (PO system)
Click on Cloud To On-Premise
Add Backend System as SAP Process Integration and Click Next
Select Protocol as HTTP and click Next
Add host and port of Backend System and click Next
In Virtual Host and port don’t put the same name and port as above
Select Principle Type as None and Click Next
Check the summary, select internal host checkbox and select Finish
System should get added
Click on Add button under Resources Accessible to add url path as”/” this is to consider all the resources after “/”
With this we have configured our backend system and now we will check in SAP Cloud Platform, API Management whether we can access SOAP services from PO system
Let’s take one step back and deploy IFLOW from HCI tenant in PO system
Log-on to N75 system and click on Deploy, fill in the details and click Next
Now the IFLOW with SOAP End point should be available in PO system and should be in started state
Click on the IFLOW and say View End points
Copy the SOAP Endpoint URL as we will be using the same SOAP endpoint in API Management
For More Details Refer Documentation
Let’s start Managing SOAP Endpoints from SAP Cloud Platform, API Management!
Open SAP Cloud Platform Cockpit from where I can see under Connectivity – Cloud Connectors the successful connection to the on-prem system.
That’s All you need now let’s go to API Portal ->Services->click on API Management Tile->click on Access API Portal.
Click on Develop and Navigate to API Providers
Create API Provider and fill in the following details
Navigate to Authentication and give backend system details
In my case I am connecting to N75 PO system and catalog service settings look like this
To test the new connectivity, just create a new API Proxy. Give API Provider as “PISYS” and give URL(which we have copied above from PO system) for eg
and Save it.
Navigate to Test and click on the API provide Basic Authorization
Post a request by giving payload in Body and a response 200 OK should come
Let’s Manage our SOAP Endpoint!
Now I want to prevent unauthorized access to our API hence would enforce verification of the application key in order to access SOAP Endpoint.
