Code Examples
Below are very simple example secret key signature authentication implementations of authentication in a couple of different languages.
Each example is annotated with todo
notes that you must address before the code is usable. Examples contain at least an HTTP JSON API call with a signature against the Wyre production API (the testwyre.com environment URI is commented out but included).
