Đặc tả API

• Content-Type: application/x-www-form-urlencoded

Dữ liệu truyền vào api

Tạo thông tin chứng thực

mac = HMAC(hmac_algorithm, key1, hmac_input)

Trong đó:

• hmac_algorithm: Là phương thức bảo mật do ứng dụng đăng ký với ZaloPay, mặc định là HmacSHA256
• key1: Là Mac Key do ZaloPay cung cấp cho ứng dụng lúc đăng ký ứng dụng
• hmac_input: appid +”|”+ apptransid +”|”+ appuser +”|”+ amount +"|"+ apptime +”|”+ embeddata +"|"+ item +"|"+ paymentcoderaw

Tham số api trả về

• Content-Type: application/json
