Quick Navigation
Interoperability Layer
- All APIs return results using Ledger’s corresponding IDs instead of Transak’s unique IDs. An interoperability layer is implemented to translate conventions supported by Transak into those supported by Ledger.
- For blockchain networks, mappings of naming conventions are maintained to consistently represent the same blockchain in both Transak and Ledger systems. This mapping is utilized across various APIs, such as Capabilities and Quote.
- For cryptocurrencies, the naming conventions follow Ledger’s standard, retrieved from Ledger’s currency API based on cryptocurrency symbols and associated networks.
Authorization
All requests require authentication via an API key in the header.
