Figure 1: Validation Flow

VERSION 2 (CURRENT VERSION)

By default, all requests receive the v2 version of the REST API. Requests will be made with version number via the Accept header.

Accept: application/vnd.faraday.spectrum.v2+json

VERSION 1

Accept: application/vnd.faraday.spectrum.v1+json

SCHEMA

Communication with Spectrum is done in JSON format, every request and response must have Content-Type: application/json;charset=UTF-8 in header.

SECURITY

Spectrum takes some security measures to be sure that responses to API calls belongs to our customers.
Every customer is given two system-wide-unique keys: public and secret keys.
Public key is sent with Spectrum requests. It can be used in customer's service to verify if request is made from Spectrum:

Accept: application/vnd.faraday.spectrum.v2+json 
Content-Type: application/json;charset=UTF-8 
X-Api-Key: fJLFhUWTxF8LdNZnvG23

Private key resides in service to be integrated. It's used to verify response is generated by customer.

Spectrum expects to get two headers in response:
• X-Timestamp, UNIX timestamp value.
• X-Auth: Value of following function: SHA-256(<API Secret>-<UNIX Timestamp>)

Example: If your API secret is OeaH2OTRCJa8REtSvKXb then you can use following Java code to generate X-Auth value.

char[] DIGITS = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f' };
MessageDigest digest = MessageDigest.getInstance("SHA-256");
byte[] bytes = digest.digest("OeaH2OTRCJa8REtSvKXb-1501580580".getBytes());
int length = bytes.length;
char[] out = new char[length << 1];
int i=0;
for(intj=0;i<length;i++){
    out[(j++)] = DIGITS[((0xF0 & bytes[i]) >>> 4)]; 
    out[(j++)] = DIGITS[(0xF & bytes[i])];
}
return new String(out);

Accept: application/vnd.faraday.spectrum.v2+json
Content-Type: application/json;charset=UTF-8
X-Timestamp: 1501570580
X-Auth: f7cd126b700c2626b71dfd65ba6acc7e51f340c7872e7af5a0af249d80271c15
