Capability Overview

Cloud Integration

Build and run integration flows across cloud, on-premise, and hybrid landscapes for A2A, B2B, and B2G scenarios. Supports 80+ adapters and real-time message processing.

Core Components:

• Integration Flows (iFlows) - Visual message processing pipelines
• Adapters - Protocol/application connectors (SFTP, HTTP, OData, RFC, AMQP, Kafka, etc.)
• Message Mapping - Graphical/XSLT/Groovy transformations
• Data Stores & Variables - Persistence for stateful processing
• Security Material - Keystores, credentials, PGP keys

API Management

Complete API lifecycle management with security, traffic control, and developer engagement.

Core Components:

• API Proxies - Facade layer for backend services
• Policies (34 types) - Security, traffic, mediation rules
• Developer Hub - API portal for developers
• Products - API bundles with access control
• Analytics - Usage metrics and insights

Event Mesh

Publish and consume business events across your enterprise ecosystem for event-driven architectures.

Edge Integration Cell

Hybrid runtime for processing data within private landscapes while designing in the cloud. Deploy on Kubernetes (EKS, AKS, GKE, OpenShift, RKE2).

Integration Advisor

AI-powered B2B content development supporting UN/EDIFACT, SAP IDoc, ASC X12. Creates Message Implementation Guidelines (MIGs) and Mapping Guidelines (MAGs).

Trading Partner Management

Streamline B2B relationships with partner profiles, agreement templates, and automated runtime artifact generation. Supports AS2, SFTP, FTP protocols.

Integration Flow Structure

Sender → [Adapter] → Integration Process → [Adapter] → Receiver
                           ↓
              ┌────────────┴────────────┐
              │  Message Processing     │
              │  - Content Modifier     │
              │  - Router/Filter        │
              │  - Mapping              │
              │  - Splitter/Aggregator  │
              │  - Script               │
              │  - External Call        │
              └─────────────────────────┘

Common Flow Steps

| Category | Steps | |----------|-------| | Routing | Router, Filter, Multicast, Recipient List | | Transformation | Content Modifier, Mapping, Converter, Script | | Splitting | General Splitter, Iterating Splitter, EDI Splitter | | Persistence | Data Store, Write Variable, JMS Send | | External | Request Reply, Send, Poll Enrich, Content Enricher | | Security | Encryptor, Decryptor, Signer, Verifier | | Error Handling | Exception Subprocess, Escalation Event |

Adapter Categories

Protocol Adapters: HTTP, HTTPS, SFTP, FTP, AMQP, JMS, Kafka, AS2, AS4, SOAP, OData Application Adapters: SuccessFactors, Ariba, Salesforce, ServiceNow, Workday Database Adapters: JDBC (Oracle, SQL Server, PostgreSQL, HANA, DB2) Cloud Adapters: AWS (S3, SQS, SNS), Azure (Service Bus, Storage), Google Cloud

Scripting Guidelines

Prefer standard steps over scripts. When scripting is necessary:

// Access message body
def body = message.getBody(String.class)

// Access headers
def header = message.getHeader("HeaderName", String.class)

// Access properties
def prop = message.getProperty("PropertyName")

// Modify body
message.setBody(newBody)

// Add header
message.setHeader("NewHeader", "value")

// Logging (use SLF4J)
def log = org.slf4j.LoggerFactory.getLogger("script")
log.info("Processing message")

Best Practices:

• Use XmlSlurper.parse(Object) instead of parseText(String) for large payloads
• Use StringBuilder for string concatenation
• Never use TimeZone.setDefault() (VM-wide impact)
• Never write credentials to headers (tracing exposes them)

API Management Development

Client → Proxy Endpoint → [Policies] → Target Endpoint → Backend
              ↓                              ↓
         PreFlow                        PreFlow
         Conditional Flows              Conditional Flows
         PostFlow                       PostFlow

         Fault Rules                    Fault Rules

Policy Categories

| Category | Policies | |----------|----------| | Security | OAuth 2.0, Verify API Key, Basic Auth, SAML, Access Control | | Traffic | Quota, Spike Arrest, Concurrent Rate Limit, Response Cache | | Mediation | Assign Message, Extract Variables, JSON/XML Transform, XSL Transform | | Extension | JavaScript, Python Script, Service Callout | | Threat Protection | JSON/XML Threat Protection, Regular Expression Protection | | Logging | Message Logging, Statistics Collector |

Common Policy Attributes

<PolicyName enabled="true" continueOnError="false" async="false">
  <!-- Policy configuration -->
</PolicyName>

Message Quality of Service

Exactly-Once Processing

Use when duplicates must be prevented:

1. JMS Queues - Transactional message storage
2. Idempotent Process Call - Duplicate detection via ID mapping
3. Data Store - Persistent message tracking

Idempotent Pattern

Sender → [ID Mapping] → Check Duplicate → Process → [ID Mapping Complete]
                              ↓ (duplicate)
                         Return Cached Response

Troubleshooting

Common Issues

Monitoring Hierarchy

Integration Suite → Monitor → Integrations and APIs
    ├── Message Processing → All Integration Flows
    ├── Manage Integration Content → Deployed Artifacts
    ├── Manage Security → Keystores, Credentials
    └── Manage Stores → Data Stores, Variables, Queues
