API Endpoint

All API requests should use the application/json content type, and must be encrypted with SSL (HTTPS).

API Authentication

CoinStep API requires authentication, by providing 3 parameters API Key, Signature and Nonce. You can generate your API keys from your account section by visiting the 'API Keys' page.

  1. API Key

    This is simply found in your account area.

  2. Signature

    The signature is a HMAC-SHA256 encoded message which contains your nonce, user id and API key, which is generated using a secret key that can be found also on the 'API Keys' page in your account.'

  3. Nonce

    A nonce is an integer that must be increasing with every request.

A pseudo code example:

message = nonce + userid + apikey
signature = CreateSignature(message, apisecret)
