You can find more information about APIs, policies, and integrations in the SAP Business Accelerator Hub. The SAP Business Accelerator Hub is a central place where you can discover, explore, and consume pre-built integrations, APIs, and best practices for various business scenarios and industries. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP

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

To use an HTTPS endpoint from an integration flow, you can use the Open Connectors capability within SAP Integration Suite. Open Connectors is a feature that allows you to connect to over 160 third-party applications using standardized and normalized APIs. You can use the HTTP client connector to make HTTP or HTTPS requests to any endpoint that supports these protocols. You can configure the HTTP client connector with various parameters, such as URL, method, headers, query parameters, body, and authentication. References: Open Connectors | SAP Help Portal, HTTP Client Connector | SAP Help Portal

To use an API key for authentication in an HTTPS API call, you must include the API key in the message header of the content modifier step. The message header contains information related to the message, such as addressing, routing, or metadata. You can use the content modifier step to create or modify message headers using expressions or constants. The API key is typically passed as a value of a specific header field, such as Authorization or X-API-Key, depending on the API provider’s requirements. You can use the Camel Simple Expression Language to access or construct the API key value from variables, properties, or system information. References: Content Modifier | SAP Help Portal, Using Camel Simple Expression Language | SAP Help Portal

In the SAP Integration Suite, you can change the virtual host name in the Settings APIs. The Settings APIs allow you to configure various aspects of your API provider, such as the virtual host name, the base path, the authentication method, and the CORS settings. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP

The condition ProductSet/count(Product)>0 checks if the number of Product elements in the ProductSet element is greater than zero, which means that a child element “Product” exists. This condition can be used to dispatch messages only when a Product element is present. References: SAP Integration Suite | SAP Community, Integration Software | SAP Integration Suite

To examine the payload at specific processing steps in an integration flow, you must use the Trace log level. The Trace log level provides the most detailed information about the message processing, including the payload content and the headers at each step. You can use the Message Processing Log to view the trace logs for a specific message. References:  Modernize Integration with SAP Integration Suite | openSAP

To test a connection to a backend system that is provided by a Cloud Connector, you must specify the location ID as a parameter for the connection test. The location ID is a unique identifier that represents a Cloud Connector instance in a specific network location. It is used to route requests from SAP Integration Suite to the correct Cloud Connector instance and then to the backend system. You can find the location ID in the Cloud Connector administration UI under Configuration Location ID. References: Cloud Connector Connectivity Tests | SAP Help Portal, Cloud Connector Configuration | SAP Help Portal

The “Trace” log level expires after 10 minutes and the log files are removed after 1 hour. The “Trace” log level is the most detailed log level that can be set for an integration flow. It records all the information about the message processing, such as headers, properties, payloads, attachments, and exceptions. However, it also consumes more resources and storage space than other log levels. Therefore, it is recommended to use it only for troubleshooting purposes and for a short duration. The “Trace” log level can be activated from the Monitor Message Processing view or from the integration flow editor. References: Log Levels | SAP Help Portal, Activating Trace Log Level | SAP Help Portal

The following capabilities within SAP Integration Suite are core for integration: Integration Assessment, Cloud Integration, and API Management. Integration Assessment allows you to evaluate your integration landscape and strategy and identify the best-fit integration technologies and tools for your scenarios. Cloud Integration allows you to design, deploy, and monitor integration flows between cloud and on-premise systems using various adapters and protocols. API Management allows you to create, publish, secure, and monitor APIs across different environments and platforms. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP
