SIGMA API (S-API): Efficient Data Access for Professional Partners

With the SIGMA API (S-API), our bank provides a powerful interface that enables asset managers, family offices, and fiduciaries to securely and efficiently integrate up-to-date banking data into their systems.

The S-API delivers daily consolidated data on positions, transactions, assets, and market prices in a standardized CSV format.

In addition, all bank documents are available as PDF files – including corresponding index files for automated processing within internal systems.

Another key advantage: Historical transaction data can also be retrieved – going back to the client's initial onboarding date.

Your benefits at a glance:

• Daily data delivery: Positions, transactions, asset, and market data
• Full document access: All bank documents as PDFs – incl. structured index files
• Historical data access: Complete tracking of all transactions since client onboarding
• Secure transmission: Data delivery via SFTP – either via our server or the client's
• Standardized format: Uniform, structured CSV files for seamless integration
• Transparent documentation: Technical specifications and integration guide provided in a comprehensive API documentation

With the SIGMA API, we lay the foundation for modern, digital collaboration – reliable, secure, and fully integrated into your existing system landscape.
