Download OpenAPI specification:Download

URL: https://www.six-group.com/en/products-services/banking-services/blink.html

This is the specification of the bLink 'custody-services' module API. (as implemented by providers (e.g. financial institutions) and used by SIX) It is part of the OpenWealth APIs for the connectivity between custody banks and WealthTechs (e.g. Portfolio Management Systems). This API allows the user to receive data from custody banks regarding accounts and positions. The API is designed to be used for either update end of day data batches or single near-realtime account/position information. Furthermore, this API allows the user to receive data from custody banks regarding transactions. In this version only transactions which include effective cash or securities movements are in scope and corporate actions are delivered only on a informative basis.
