The Transfers API allows for the automation of deposits and withdrawals to your account.


Endpoint


The Transfers API is a REST API. All its methods are accessible by the following endpoint:

https://api.xena.exchange/transfers/...


Authentication


Authentication for the Transfers API requires the same information as the Trading API. Instead of sending some initial message like Logon, each call to the REST Transfers API must contain 4 HTTP headers:

X-AUTH-API-KEY

X-AUTH-API-PAYLOAD

X-AUTH-API-SIGNATURE

X-AUTH-API-NONCE

Nonce (UNIX nanoseconds timestamp) must be unique for each request and no older than 60 seconds.
