STEX provides all the core exchange functionality, and additional merchant tools available via the HTTP API where all returned messages are in JSON. It's much easier to work with the API by using one of the clients provided by STEX, so while this page describes the API in case you want or need to build your own client, the examples use the PHP or NodeJS client. To view and downloads the clients, please visit:
In order to use the API functions, you must have an API key and API secret, which is generated in the user profile.
