ZebPay Trade API

This endpoint allows users to read order data, create a new order, or cancel a previously placed order.Signature Generation for POST Methods:The following JavaScript code should be added to the Pre-request Script tab in Postman. It automatically generates the required signature and includes the API key and signature in the request headers.// Import crypto for HMAC-SHA256 signature calculationconst CryptoJS = require('crypto-js');// API key and secretconst APIKEY = '';const SECRET = '';// Generate the current timestampconst timestamp = Date.now(); // Unix time in milliseconds//read boday data and pass update timestampconst body = pm.request.body.rawconst payload = JSON.parse(body);payload.timestamp = timestamp;// Stringify the payloadconst payloadString = JSON.stringify(payload);// Function to calculate HMAC-SHA256 signaturefunction calculateSignature(payload, secret) { const hash = CryptoJS.HmacSHA256(payload, secret); return hash.toString(CryptoJS.enc.Hex);}// Calculate the signatureconst signature = calculateSignature(payloadString, SECRET);// Set headers dynamicallypm.request.headers.upsert({ key: "X-AUTH-APIKEY", value: APIKEY,});pm.request.headers.upsert({ key: "X-AUTH-SIGNATURE", value: signature,});// Replace request body with the dynamically generated payloadpm.request.body.update(payloadString);Signature Generation for GET Methods:// Import crypto for HMAC-SHA256 signature calculationconst CryptoJS = require('crypto-js');// API key and secretconst APIKEY = '';const SECRET = '';// Function to calculate HMAC-SHA256 signaturefunction calculateSignature(payload, secret) { const hash = CryptoJS.HmacSHA256(payload, secret); // Use CryptoJS for HMAC return hash.toString(CryptoJS.enc.Hex); // Convert to hexadecimal}// Generate a timestampconst timestamp = Date.now(); // Current Unix timestamp in milliseconds// Access the query parameters from the request URLlet queryParams = pm.request.url.query;// Convert query parameters into a key-value objectlet queryObject = {};queryParams.each(param => { queryObject[param.key] = param.value;});// Update or set the parameter dynamicallyqueryObject['timestamp'] = Date.now() // Update 'timestamp' parameter// Convert query parameters to query stringconst queryString = Object.entries(queryObject) .map(([key, value]) => `${encodeURIComponent(key)}=${encodeURIComponent(value)}`) .join('&');// Generate the signatureconst signature = calculateSignature(queryString, SECRET);// Set headers dynamicallypm.request.headers.upsert({ key: "X-AUTH-APIKEY", value: APIKEY,});pm.request.headers.upsert({ key: "X-AUTH-SIGNATURE", value: signature,});// Update the URL with the query parameterspm.request.url.query.clear(); // Clear existing query paramsqueryString.split('&').forEach((param) => { const [key, value] = param.split('='); pm.request.url.query.add({ key, value });});
