  • To write an application around a Daml ledger, you’ll need to interact with the Ledger API from another language. Every ledger that Daml can run on exposes this same API and the set of services.

  • Learn how to interact with a Daml ledger using a simpler API - the JSON API. It provides the basic functionalities such as creating contracts, exercising choices, querying the active contract set, and listing all known parties. Make sure you go over the HTTP status codes and error messages.

  • JavaScript libraries are the recommended way to build a frontend that interacts with Daml. Make sure you understand what each of the libraries offers.
