Integration Options with Zalion (Overview)
Zalion integrates flexibly into existing enterprise environments — whether ERP, SRM, email, or file systems. All data exchange is encrypted, auditable, and fully isolated per customer within Zalion's AWS environment (eu-central-1).
Depending on your system landscape and requirements, three fundamental integration methods are available:
1. Cloud-Based API Integration
Zalion connects directly to your cloud systems via secure API interfaces. This method offers real-time read and write access, full control over data scopes and permissions, and trigger- or schedule-based interaction.
Typical authentication: OAuth 2.0, API keys, or custom tokens
Recommended for: Modern cloud systems (e.g., SAP S/4HANA Cloud, Microsoft 365, Google Workspace) where real-time interaction and full integration depth are required.
2. File-Based Integration
Zalion supports secure file-based data exchange via SFTP servers, network folders (SMB/NAS), or SharePoint/OneDrive. Exchange typically follows a fixed schedule (e.g., 4× daily) in formats such as XML, JSON, or CSV.
Typical authentication: SSH keys (SFTP), network credentials, or OAuth 2.0 via Microsoft Entra ID (SharePoint)
Recommended for: On-premise systems (e.g., SAP ECC, Navision) or environments where API integration is not possible.
3. Middleware Integration
Organizations using integration platforms such as Boomi, MuleSoft, SnapLogic, Lobster, or myOpenFactory can connect Zalion via secure middleware endpoints. This leverages existing transformation logic and routing.
Typical authentication: Tokens, keys, or signed payloads
Recommended for: Organizations with standardized IT architectures or complex system landscapes.
Comparison Table
| Integration Method | System Type | Real-Time Capable | Access Requirement | Encryption |
|---|---|---|---|---|
| API Integration | Cloud systems | Yes | Firewall whitelisting, OAuth | TLS 1.3 |
| SFTP File Exchange | On-premise/Cloud | No (batch) | SFTP credentials & IP whitelist | AES-256 |
| Network Folder Access | On-premise systems | No (batch) | Folder access & IP whitelist | Internal policy |
| SharePoint/OneDrive | Microsoft 365 | Limited (webhooks) or batch | Entra ID admin consent | TLS 1.2+/1.3 & OAuth 2.0 |
| Middleware | Hybrid/Cloud/On-premise | Depends on configuration | Middleware endpoint | Platform-dependent |
Core Principles
All integration options follow Zalion's core principles:
- Isolated data environments per customer
- End-to-end encryption (AES-256 / TLS 1.3)
- Strict access control (RBAC, IP filtering, auditing)
- Jointly defined data contracts (file structure, access windows, frequency)
We work closely with your IT and procurement teams to define the most suitable integration path — with security and compliance always at the center.
