Cloud Integration: OData API on API Business Hub
The OData API of SAP Cloud Integration enables you to access the stored data (e.g. to implement a monitoring project) or to update data (e.g. to create/update/delete partner directory content). In the past these OData API entities were only described in SAP Help Portal (see SAP Help Portal: SAP Cloud Integration – OData API), but with SAP Cloud Integration 14-Apr-2018 release (v2.39.x) the first version of this API is published in the SAP API Business Hub.
New with SAP Cloud Integration 7 July 2018 release:
API package of SAP Cloud Integration is enhanced by access to “Design” section. These API enhancements are further detailed in Blog: Cloud Integration – Remote OData API’s for Integration Flows and in SAP Help Portal: Integration Content Designtime – OData API.
New with SAP Cloud Integration 4 August 2018 release:
Integration Flow entity is added to “Integration Content” API.
The new API “Security Content” is provided with “Certifacte-to-User-Mapping” entity.

Image 1: API Package “SAP Cloud Integration” in SAP API Business Hub
You have two different opportunities to test APIs directly in the API Business Hub. Either you use the API Sandbox or you configure an API environment for your tenant account. For both options you need to be logged on with your SAP Community User.
It is possible to directly test the provided GET methods via API Sandbox (see SAP Help Portal: SAP API Business Hub- Trying Out PIs in Sandbox Environment), which is the default “Try out” feature.
The API Sandbox contains all test data for the provided APIs.
Example: GET All Deployed Integration Artifacts
Select the API, which you want to test.
Image 2: Select API
In “API References” select the required entity to get the corresponding method list.
Image 3: Open method list of an entity
Click on “Try out” of a “GET” method.
Image 4: Start test by clicking on “Try out”
Enter possibly required parameter values for the request and click on “Execute” button.
Image 5: Trigger request by clicking on “Execute” button
Afterwards you could see the received response directly underneath.

Your Tenant Account
Alternatively to API Sandbox, you could test all methods (GET, POST, PUT and DELETE) in your SAP Business Technology Platform account by configuring API environment (see SAP Help Portal: SAP API Business Hub – Trying Out APIs in a Productive Environment).
For enabling tests with your account, click on “Configure Environments” for an opened API.
Image 7: Configure an API environment for “Integration Content” API
Select the region specific starting URL of your tenant account:
Image 8: Select region specific starting URL of your tenant account
Enter a display name, the account short name and the SSL host to complete the required URL for the API call and add your user credentials to complete the configuration.
The API environment contains the list of the display names for your configured environments plus Sandbox, which is selected by default. For test the API in your account you need to select the relevant environment display name before executing the method calls.
Image 9: Select display name of your account
As prerequisite for API test via your configured API environment your user needs to be assigned to the required roles (see SAP Help Portal: SAP Cloud Integration – Tasks and Required Roles).
CSRF Token Handling
For each write access a CSRF token is required. The corresponding fetch method “CSRF Token Handling” is part of each API with at least one write method.
To get the required CSRF token, at first the GET method needs to be called with the parameter X-CSRF-Token = Fetch.
Image 10: Fetch CSRF-Token
The received token must be copied from the response header.
Image 11: Copy CSRF-Token from response header
Afterwards this copied token needs to be entered into the X-CSRF-Token parameter of the POST, PUT or DELETE method.
Image12: Example: Paste the copied CSRF-Token into the corresponding X-CSRF-Token parameter field of DELETE IntegrationRuntimeArtifacts to undeploy an integration flow.
It is planned to further enhance the OData API of SAP Cloud Integration and to update this package in the SAP API Business Hub accordingly.
For example the API “Integration Content” will be further enhanced by new entity for designtime packages.
