WestWallet API expects to receive X-API-KEY, X-ACCESS-SIGN and X-ACCESS-TIMESTAMP in the header of each of your request.

X-API-KEY - your public key;

X-ACCESS-TIMESTAMP - timestamp (use unix timestamp);

X-ACCESS-SIGN - HMAC-sha256 request body signature (composed of lines, comprising the timestamp and JSON-representation of the request body data) signed by your private key. For GET requests it should be made with JSON-dump of query parameters.

See an example how to form a string for generating signature at Python examples
