SAP BTP Connectivity provides secure access from SAP BTP applications to remote services across cloud, on-premise, and VPC environments.
Core Components
| Destination Service | Manages connection metadata, authentication, routing
| Connectivity Service | Enables Kubernetes workloads via Cloud Connector
| Cloud Connector | Reverse proxy for secure on-premise tunneling
| Connectivity Proxy | Kubernetes component for on-premise access
| Transparent Proxy | Kubernetes component for unified destination access
Supported Environments: Cloud Foundry, ABAP Environment, Kyma Supported Protocols: HTTP/HTTPS, RFC, TCP (SOCKS5), LDAP/LDAPS, Mail
Quick Start
Create HTTP Destination (Cloud Foundry)
-
Navigate: Connectivity > Destinations in BTP Cockpit
-
Select: Create > From Scratch
-
Configure:
Name: my-destination
Type: HTTP
URL: [https://api.example.com](https://api.example.com)
ProxyType: Internet
Authentication: OAuth2ClientCredentials
clientId: <your-client-id>
clientSecret: <your-client-secret>
tokenServiceURL: [https://auth.example.com/oauth/token](https://auth.example.com/oauth/token)
Set Up Cloud Connector
-
Download from SAP Tools
-
Access:
[https://localhost:8443](https://localhost:8443`) -
Login:
Administrator/manage(change immediately) -
Add subaccount connection
Access Destination in Application (Node.js)
const { getDestination } = require('@sap-cloud-sdk/connectivity');
const destination = await getDestination({ destinationName: 'my-destination' });
Connectivity Scenarios
Cloud-to-Cloud
ProxyType: Internet
Authentication: OAuth2ClientCredentials | OAuth2SAMLBearerAssertion
Cloud-to-On-Premise
ProxyType: OnPremise
Authentication: BasicAuthentication | PrincipalPropagation
Requires Cloud Connector installation in on-premise network.
On-Premise-to-Cloud (Service Channels)
For on-premise systems accessing SAP BTP services via Cloud Connector.
Destination Types
| HTTP | REST/OData APIs | Internet/OnPremise | OAuth2, Basic, Certificates
| RFC | SAP systems | OnPremise | Basic, PrincipalPropagation
| LDAP | Directory services | Internet | Basic, NoAuth
| MAIL | Email protocols | Internet | Basic, NoAuth
| TCP | Generic TCP | OnPremise | Basic
Detailed configuration: See references/http-destinations.md, references/rfc-destinations.md, references/mail-tcp-ldap-destinations.md
Authentication Configuration
OAuth2ClientCredentials (Service-to-Service)
Authentication: OAuth2ClientCredentials
clientId: <client-id>
clientSecret: <client-secret>
tokenServiceURL: [https://auth.example.com/oauth/token](https://auth.example.com/oauth/token)
OAuth2SAMLBearerAssertion (User Propagation)
Authentication: OAuth2SAMLBearerAssertion
audience: <target-audience>
clientKey: <client-key>
tokenServiceURL: [https://auth.example.com/oauth2/token](https://auth.example.com/oauth2/token)
KeyStoreLocation: <certificate-location>
PrincipalPropagation (On-Premise SSO)
Authentication: PrincipalPropagation
ProxyType: OnPremise
Requires Cloud Connector X.509 certificate generation.

Cloud Connector Setup
Installation
-
Production: Windows MSI/Linux RPM packages (service registration)
-
Development: Portable archive (manual execution)
Initial Configuration
-
Access UI:
[https://<hostname>:8443](https://:8443`) -
Login:
Administrator/manage -
Change password immediately
-
Select mode: Master or Shadow
-
Add subaccount connection
Access Control
Configure on-premise resource access:
-
Backend Types: ABAP System, SAP Gateway, Non-SAP System, SAP HANA
-
HTTP Access Control: System mapping + resource paths + policies
High Availability
-
Master-Shadow: Primary + backup with synchronized config
-
Requirements: Stable network, separate machines, identical versions

Kubernetes/Kyma Connectivity
Connectivity Proxy
Enables Kubernetes workloads to access on-premise systems.
Installation:
helm install connectivity-proxy \
oci://registry-1.docker.io/sapse/connectivity-proxy \
--version <version> --namespace <namespace> -f values.yaml
Transparent Proxy
Exposes BTP destinations as Kubernetes Services.
Installation:
helm install transparent-proxy \
oci://registry-1.docker.io/sapse/transparent-proxy \
--version <version> --namespace <namespace> -f values.yaml
Usage: Create Destination Custom Resource, access as Kubernetes Service.
Complete configuration: references/kubernetes-connectivity.md
Common Issues & Troubleshooting
HTTP Error Codes
| 400 | Malformed request | Check request syntax
| 401 | Authentication failure | Verify credentials/tokens
| 405
| HTTPS instead of HTTP
| Use [http://](http://`) with port 20003
| 407
| Missing authorization
| Add Proxy-Authorization: Bearer <token>
| 503 | Cloud Connector offline | Check CC connection and Location ID
Cloud Connector Issues
Cannot connect to subaccount:
-
Verify region host URL
-
Check firewall allows outbound HTTPS
-
Verify subaccount credentials
Access denied to resource:
-
Check access control configuration
-
Verify virtual host mapping
-
Check resource path policy

Security Best Practices
Cloud Connector
-
Deploy in DMZ under IT control
-
Change default password immediately
-
Configure LDAP for user management
-
Enable audit logging (All level for production)
-
Deploy high availability (master + shadow)
Destinations
-
Use OAuth over basic authentication
-
Store credentials in Destination Service, not code
-
Enable TLS for all connections
-
Use mTLS for enhanced security
Critical Rules
Always Do
-
Change Cloud Connector default password immediately
-
Use HTTPS for all external connections
-
Configure access control before exposing resources
-
Enable audit logging in production
-
Cache tokens and destinations appropriately
Never Do
-
Expose Cloud Connector UI to internet
-
Store credentials in application code
-
Skip access control configuration
-
Modify Cloud Connector Tomcat config files
-
Run multiple master instances (split-brain)
