C_CPI_15 SAP Certified Development Associate - SAP Integration Suite Questions and Answers

An API proxy is an API that acts as a proxy for another API, which is usually the backend service that provides the actual functionality. An API proxy can be used to add security, monitoring, caching, transformation, and other features to the backend API. An API provider is a logical grouping of APIs that share a common connection to the backend service. An API provider can be used to discover and import APIs from the backend service into the API Management capability within SAP Integration Suite. The relationship between an API provider and an API proxy is that the API proxy uses the API provider as a source of information and configuration for accessing the backend service. The API proxy also provides a unique URL that can be used by clients to invoke the API without exposing the details of the backend service. References: SAP Integration Suite | SAP Community, Create an API Proxy | SAP Tutorials

he target endpoints of an API are the API provider, the API proxy, and the URL of the original API. The API provider is the system or application that exposes the interface and functionality of the API. The API proxy is the intermediary component that mediates the requests and responses between the API consumer and the API provider. The URL of the original API is the address that identifies the location and resource of the API. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP

To find out which entity sets are available in the OData V2.0 interface, you must retrieve the metadata document from the interface. The metadata document is an XML document that describes the data model of the OData service, including the entity types, entity sets, associations, functions, and actions. The metadata document can be accessed by appending $metadata to the service root URL of the OData service. For example, if the service root URL is https://services.odata.org/OData/OData.svc/, then the metadata document URL is https://services.odata.org/OData/OData.svc/$metadata. The metadata document can be used to discover the structure and capabilities of the OData service and to generate client code or proxies. References: Overview (OData Version 2.0) | OData - The Best Way to REST, OData API v2 Reference | SAP Help Portal

To configure a SOAP adapter for asynchronous processing, you must set the message exchange pattern to one-way and the process settings to WS standard. The message exchange pattern defines how the sender and receiver communicate with each other using SOAP messages. The one-way pattern means that the sender sends a message to the receiver without expecting a response. The process settings define how the SOAP adapter handles errors and acknowledgements during message processing. The WS standard setting means that the SOAP adapter uses WS-ReliableMessaging protocol to ensure reliable delivery of messages and WS-Addressing protocol to identify the endpoints and actions of messages. References: Configure the SOAP (SOAP 1.x) Sender Adapter | SAP Help Portal, Configure the SOAP (SOAP 1.x) Receiver Adapter | SAP Help Portal

To save a customer ID in a data store, you can use the WRITE operation. The WRITE operation allows you to store a value in a data store entry with a specified key. You can use the WRITE operation to create or update a data store entry with a customer ID as the key and a value as the payload. References:  Modernize Integration with SAP Integration Suite | openSAP

A Timer event allows you to run integration flows directly after deployment. A Timer event is triggered by a predefined schedule or interval, such as every hour, every day, or every month. You can use a Timer event to initiate an integration process based on a time-based condition. References:  Modernize Integration with SAP Integration Suite | openSAP

If no namespace mapping exists, you must remove the namespaces to access individual entities of an HTTP call over XPath. Namespaces are prefixes that identify the source or context of an XML element or attribute. If the namespaces are not mapped to a URI, they can cause errors or conflicts when using XPath expressions. Therefore, you must remove the namespaces before applying XPath queries.

A product in the API Management capability within SAP Integration Suite is a bundle of one or more API proxies that are grouped together for a specific business scenario or use case. A product is a separate artifact that can be deployed to the API business hub enterprise, which is a centralized platform for discovering, consuming, and managing APIs. A product can have its own metadata, such as name, title, description, quota limits, and so on. A product can also have its own policies that apply to all the APIs included in it. References: Create a Product | SAP Help Portal, API Business Hub Enterprise | SAP Help Portal

The API Management capability within SAP Integration Suite supports the following message protocols: SOAP, REST, and Data. SOAP is a protocol for exchanging structured XML messages between web services. REST is an architectural style for designing web services that use HTTP methods and formats. Data is a protocol for sending and receiving binary or text data over HTTP or HTTPS. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP

To split a message that contains recurring child nodes, you can use a General Splitter or an Iterating Splitter. A General Splitter allows you to split a message based on an XPath expression that defines the splitting criteria. An Iterating Splitter allows you to split a message based on an XPath expression that defines the repeating element. References:  Modernize Integration with SAP Integration Suite | openSAP

To connect an SAP backend system through the Cloud Connector with an API provider, you must use the on-premise connection type. The Cloud Connector acts as a link between SAP Integration Suite and on-premise systems, enabling secure and controlled access to the backend resources. The on-premise connection type allows you to specify the internal host and port of the backend system, as well as the virtual host and port that will be exposed to SAP Integration Suite. You can also define access control rules and protocols for the on-premise connection. References: Part 2: Connect to on-premise APIs from SAP Cloud Platform API Management Cloud Foundry Environment | SAP Blogs, How to configure SAP Cloud Connector & Create API using SCP API Management | SAP Blogs

You can use an HTTPS adapter to call an OData v4.0 interface in the Cloud Integration capability within SAP Integration Suite. An HTTPS adapter allows you to send and receive messages over HTTP or HTTPS protocols. You can use an HTTPS adapter to communicate with RESTful services, such as OData v4.0, that support HTTP methods and formats. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP

In the Cloud Integration capability within SAP Integration Suite, you can do the following things:

• Connect to multiple endpoints. You can use various adapters and protocols to connect to different systems and applications, such as SAP S/4HANA, Salesforce, SuccessFactors, and more.
• Develop custom adapters. You can use the Adapter Development Kit (ADK) to create your own adapters for specific integration scenarios and requirements. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP

 Some advantages of creating an OData interface through an API provider are automatic creation of a Swagger UI and an openAPI specification. A Swagger UI is a web-based tool that allows you to interact with the OData service and test its functionality. An openAPI specification is a standard format for describing the OData service and its metadata, which can be used by other tools and applications. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP
