SAP CPI Integration is a cloud-based approach for connecting SAP applications, non-SAP applications, APIs, databases, and business processes. SAP CPI is a commonly used term for SAP Cloud Platform Integration. In the current SAP product structure, Cloud Integration is a capability within SAP Integration Suite, which runs on SAP Business Technology Platform (SAP BTP). Cloud Integration supports application-to-application (A2A), business-to-business (B2B), and business-to-government (B2G) integration scenarios across cloud, on-premise, and hybrid environments.
Businesses often use several applications for ERP, CRM, human resources, finance, e-commerce, logistics, and customer service. These applications can use different data formats, APIs, protocols, and authentication methods. An integration platform provides a central layer for exchanging and processing information between these systems.
This guide explains the key concepts, features, architecture, and practical use cases of SAP Cloud Integration. It also covers AEO and GEO considerations for creating clear, technically accurate content that can be understood by users and modern search systems.
What Is SAP CPI Integration?
SAP CPI Integration is the process of connecting different applications and systems through SAP Cloud Integration. The platform receives messages from a sender system, processes the information according to an integration flow, and delivers the resulting message to a receiver system.
A simple integration can look like this:
SAP S/4HANA → Cloud Integration → Third-Party Application
For example, an organization may use SAP S/4HANA for ERP and a separate CRM platform for customer management. Customer, order, product, or invoice information may need to move between the two systems.
Cloud Integration can receive the information, transform its structure, route it to the correct destination, and process the message according to the configured integration logic.
SAP describes Cloud Integration as a capability for connecting SAP and non-SAP systems and for transforming, routing, orchestrating, and processing messages across different environments.
SAP CPI and SAP Integration Suite
The term SAP CPI remains widely used in technical searches and discussions. Current SAP documentation places Cloud Integration within SAP Integration Suite.
SAP Integration Suite is an enterprise integration platform as a service (iPaaS). Its capabilities include Cloud Integration, API Management, Open Connectors, Integration Advisor, Trading Partner Management, Integration Assessment, and Migration Assessment, among others.
Cloud Integration focuses on message-based application and process integration. API Management provides capabilities for managing APIs, including security, traffic management, monitoring, and lifecycle governance. Open Connectors provides prebuilt connectivity for more than 160 non-SAP applications according to SAP documentation.
Therefore, when someone searches for SAP CPI Integration today, the relevant current technology is generally SAP Cloud Integration within SAP Integration Suite.
Key Concept: Integration Flow
An integration flow, commonly called an iFlow, is one of the central concepts in SAP Cloud Integration.
An integration flow defines how a message is processed. It identifies the sender and receiver, establishes connectivity through adapters, and defines the processing steps applied to the message. SAP provides a graphical editor for modeling these processing steps.
A basic flow can contain:
Sender → Adapter → Processing Steps → Adapter → Receiver
For example:
E-commerce System → HTTPS → Mapping → Routing → S/4HANA
The sender provides the source message. The adapter establishes the technical connection. Processing steps modify or evaluate the message. The receiver adapter delivers the processed information to the target system.
Integration flows are stored inside integration packages, which can also contain artifacts such as value mappings and APIs.
Key Concept: Senders and Receivers
A sender is the system that provides a message to an integration flow. A receiver is the system that receives the processed message.
A sender or receiver can represent an SAP application, third-party application, API, file server, database, or another supported endpoint.
For example:
SAP SuccessFactors → SAP Cloud Integration → SAP S/4HANA
In this scenario, SuccessFactors can act as the sender, while S/4HANA can act as the receiver.
A single integration flow can also contain multiple receivers when the business scenario requires information to be delivered to more than one destination.
SAP documentation describes sender and receiver elements as representations of remote systems connected to the integration flow.
Key Concept: SAP CPI Adapters
Adapters provide the technical connection between an integration flow and an external system.
The adapter determines how the message is communicated between the sender or receiver and Cloud Integration. SAP documentation identifies adapters as the mechanism used to specify the technical protocol for connecting systems to an integration flow.
Common technologies used in SAP integration scenarios include HTTPS, REST, SOAP, SFTP, OData, IDoc, and JDBC, depending on the system and integration requirement.
For example, an external application may provide a REST API. An integration flow can communicate with that API using an appropriate HTTP-based connection.
Another system may exchange files through SFTP. The integration flow can use the relevant file-transfer connectivity for that scenario.
The correct adapter depends on the source, target, protocol, authentication requirements, and data-exchange method.
Key Concept: Message Mapping
Message mapping changes the structure of information from a source format into a target format.
Different systems may use different field names.
For example, a source system could send:
customer_id
while the target application expects:
CustomerNumber
A mapping can connect these fields.
Mapping can also involve data transformation, field conversion, value mapping, and structural changes. SAP Cloud Integration provides mapping capabilities as part of integration-flow development.
Mapping becomes particularly important when integrating systems from different vendors because each application can use its own data model.
Key Concept: Message Transformation
Message transformation changes the format or content of a message so that the target system can process it.
For example, one application may send XML while another application expects JSON.
An integration flow can process the message and convert or restructure the information according to the target interface.
Transformation can also involve filtering unnecessary information, adding required values, combining information, splitting messages, or modifying individual fields.
The transformation requirements depend on the source and target systems.
Key Concept: Message Routing
Message routing determines where a message should be sent based on defined conditions.
For example, an organization may process orders differently based on country, customer type, product category, or another business value.
A content-based router can evaluate information inside a message and send it to the appropriate receiver. SAP documents content-based routing as one example of an enterprise integration pattern supported by Cloud Integration.
A simplified scenario could be:
Order → Country Check → Domestic System / International System
Routing allows one integration flow to handle different processing paths.
Key Concept: Integration Packages
Integration packages provide an organizational structure for integration artifacts.
A package can contain integration flows, value mappings, APIs, and other related content. SAP also provides prepackaged integration content for certain business scenarios.
Using a structured package system can make it easier to organize integration content according to business processes, departments, or applications.
For example, an organization could maintain separate packages for:
Finance
Sales
Human Resources
Procurement
The actual structure depends on the organization’s integration architecture and governance model.
Key Features of SAP CPI Integration
Cloud Integration provides capabilities for designing and running integration flows across cloud, on-premise, and hybrid landscapes.
One important feature is data transformation. Messages can be modified to meet the requirements of different applications.
Another feature is message routing, which allows messages to be directed according to defined conditions.
Connectivity through adapters allows integration flows to communicate with different systems and protocols.
Message monitoring provides information about integration processing and supports troubleshooting.
API integration allows Cloud Integration to work with API-based applications. SAP Integration Suite also provides API Management for API security, traffic management, monitoring, and lifecycle governance.
Prebuilt integration content can also reduce development work for supported business scenarios. SAP provides integration packages containing artifacts such as integration flows, mappings, and documentation.
SAP CPI Integration in Cloud and Hybrid Environments
Cloud Integration can connect applications located in different environments.
For example:
Cloud Application → Cloud Integration → Cloud Application
It can also support:
Cloud Application → Cloud Integration → On-Premise SAP System
SAP’s standard cloud deployment model allows sender and receiver systems to reside either in cloud environments or on-premise landscapes.
This makes Cloud Integration relevant for organizations that are moving applications to the cloud while continuing to operate existing on-premise systems.
The exact connectivity architecture depends on network configuration, authentication, security requirements, and the technologies used by the connected applications.
SAP CPI Integration and API Management
APIs are a major part of modern application integration.
Cloud Integration can process API-based messages and integrate API endpoints into business processes. SAP Integration Suite also provides API Management for managing APIs.
API Management can apply authentication and authorization controls, traffic policies, monitoring, and lifecycle governance. SAP describes API Management as a complementary capability to Cloud Integration.
For example:
Mobile Application → API Management → Cloud Integration → SAP S/4HANA
The API layer can control access to the service while Cloud Integration handles backend connectivity and processing.
This separation can help organizations manage integration logic and API governance as separate but connected concerns.
SAP CPI Integration and Open Connectors
Third-party applications can have different APIs and authentication models. Creating custom connectivity for every application can increase integration complexity.
SAP Integration Suite includes Open Connectors, which provide prebuilt connectivity for more than 160 non-SAP applications according to SAP documentation.
Open Connectors can be relevant when organizations need to connect applications from different vendors.
For example, a company may operate an SAP ERP system and several non-SAP cloud applications. Prebuilt connectors can provide an additional connectivity option where supported.
The exact availability and capabilities depend on the application and connector.
SAP CPI Integration Use Cases
SAP CPI Integration can support many business and technical scenarios.
SAP S/4HANA Integration
Organizations can connect S/4HANA with other SAP applications, third-party systems, APIs, and business services.
A typical scenario could involve sending sales order information from an external platform into S/4HANA.
CRM Integration
A CRM application can exchange customer and sales information with SAP systems.
For example:
CRM → Cloud Integration → S/4HANA
Customer or order information can be transformed before reaching the target system.
E-Commerce Integration
An online store can exchange product, inventory, customer, and order data with SAP systems.
A typical process may look like:
E-commerce Platform → Cloud Integration → SAP S/4HANA
Cloud Integration can process the incoming order and convert its structure into the format required by the SAP application.
Human Resources Integration
HR applications can exchange employee-related information with SAP and non-SAP systems.
Integration can support processes such as employee data synchronization, organizational information exchange, and other supported HR scenarios.
File-Based Integration
Some applications continue to exchange data through files.
An integration flow can process files from supported locations and transform the information before delivering it to another application.
SFTP is one technology commonly used for secure file exchange.
B2B Integration
Businesses can exchange documents and information with suppliers, customers, logistics companies, and other trading partners.
SAP Integration Suite provides capabilities for B2B integration and trading partner management.
SAP CPI Integration Monitoring
Monitoring is important for understanding whether integration flows are processing messages successfully.
Cloud Integration provides monitoring information for integration content and message processing. SAP also provides an OData API that can be used to access Cloud Integration resources, including monitoring data, subject to authorization.
Monitoring can help identify issues such as:
Authentication errors
Unavailable endpoints
Invalid message structures
Mapping problems
Application errors
Configuration issues
A monitoring process should be designed around the business importance of each integration.
SAP CPI Integration Error Handling
Errors can occur at different stages of an integration.
A source application may send invalid information. A target application may reject a message. An API may become unavailable. A certificate may expire. Network connectivity may fail.
Cloud Integration provides processing and error-handling capabilities that can be incorporated into integration flows.
Enterprise-grade integration design should account for resilience, resource management, loose coupling, monitoring, and graceful failure handling. SAP’s design guidance emphasizes these qualities for mission-critical integration flows.
For example, a temporary endpoint problem and an invalid business record should not necessarily be handled in the same way.
SAP CPI Integration Performance Considerations
Integration performance depends on factors such as message size, message volume, processing steps, mappings, external systems, and the design of the integration flow.
SAP notes that processing steps consume tenant resources and that some operations, including mapping, security processing, XPath-related operations, and validation, can have specific resource impacts.
A complex integration flow with many processing steps may require more resources than a simple flow.
For this reason, integration design should consider the expected number of messages, message size, processing frequency, external endpoint behavior, and required transformations.
SAP CPI Integration Best Practices
A well-designed integration should start with a clear definition of the source, target, business process, data structure, protocol, authentication method, and expected message behavior.
Integration flows should remain readable and maintainable. SAP recommends considering readability, resilience, high availability, resource management, loose coupling, and graceful failure handling when designing enterprise-grade integration flows.
Clear naming is also useful. SAP provides naming guidance for integration packages, flows, message queues, and related resources.
Monitoring and error handling should be considered during the design stage. Security requirements should also be defined before an integration is deployed to production.

Using both the familiar term SAP CPI and the current term Cloud Integration can also help address historical search terminology while accurately describing SAP’s current product structure.
SAP CPI Integration vs Point-to-Point Integration
Point-to-point integration creates direct connections between applications.
For example:
System A → System B
System A → System C
System B → System C
As the number of applications increases, managing individual connections can become more complex.
An integration platform provides a centralized layer for connectivity, transformation, routing, processing, and monitoring.
The suitable architecture depends on the number of applications, business processes, security requirements, data volume, integration patterns, and governance requirements.
SAP Integration Suite is designed to support integration across SAP and non-SAP applications in cloud, on-premise, and hybrid environments.
