批量 SMS API 文件

快速開始

1. 在控制台創建帳戶並為您的餘額充值。
2. 打開 API 密鑰 並創建一個密鑰。首次充值後即可創建密鑰。密鑰僅顯示一次；請將其存儲為秘密。
3. 向 /sms 發送 POST 請求，包含號碼和文本。讀取返回的推廣活動 ID，然後在控制台或通過網頁掛鉤跟蹤送達情況。

身份驗證

除公開費率列表外，每個請求都需在 Authorization 標頭中攜帶您的密鑰。密鑰以 sbk_live_ 開頭。新密鑰會立即替換舊密鑰。

Authorization: Bearer sbk_live_YOUR_KEY

發送短訊

POST/sms

創建推廣活動，從餘額中扣除費用並將每條短訊排隊。號碼會被清理和去重；無法使用的號碼將在 dropped 中返回原因且不會收費。

估算發送

POST/estimate

接受與 /sms 相同的主體，並返回收件人、段數、編碼、總費用和每個國家的費用，但不收費或發送任何內容。

{ "recipients": 2, "dropped": [], "segments": 1, "encoding": "GSM-7", "cost": "0.01078", "balance": "248.31500",
  "countries": [ { "country": "GB", "recipients": 1, "cost": "0.00819" }, { "country": "BR", "recipients": 1, "cost": "0.00259" } ] }

短訊狀態

GET/sms/{message_id}

返回一條短訊：號碼、國家、段數、價格、狀態、失敗短訊的錯誤以及每個步驟的時間。

推廣活動

GET/campaigns/{campaign_id}

推廣活動及其費用、退款和每種狀態的短訊計數。

GET/campaigns/{campaign_id}/messages?offset=0&limit=100

按排隊順序的短訊，每頁最多 1,000 條。

POST/campaigns/{campaign_id}/cancel

取消尚未開始的預定推廣活動，並將其全額費用退還至餘額。

餘額及費率

GET/balance

{ "balance": "248.31500", "currency": "USD" }

GET/rates

送達網頁掛鉤

在控制台的 API 密鑰下設置網頁掛鉤 URL。當短訊達到最終狀態（送達或失敗）時，我們會將報告 POST 到該 URL。在 8 秒內以任何 2xx 狀態回應；否則將在約 11 小時內重試最多 8 次。使用 id 忽略您已處理的報告。

POST https://your-server.example/sms-status

在信任報告之前檢查簽名：使用您的網頁掛鉤秘密對 t + "." + raw body 進行 HMAC-SHA256 計算，並在恆定時間內進行比較，拒絕超過 5 分鐘的時間。

import { createHmac, timingSafeEqual } from "node:crypto";

// raw = the request body exactly as received (string), header = X-SendBulkSMS-Signature
export function verify(raw, header, secret) {
  const m = /^t=(\d+),v1=([0-9a-f]{64})$/.exec(header || "");
  if (!m || Math.abs(Date.now() / 1000 - Number(m[1])) > 300) return false;
  const want = Buffer.from(createHmac("sha256", secret).update(m[1] + "." + raw).digest("hex"));
  const got = Buffer.from(m[2]);
  return want.length === got.length && timingSafeEqual(want, got);
}

import hmac, hashlib, re, time

def verify(raw: bytes, header: str, secret: str) -> bool:
    m = re.fullmatch(r"t=(\d+),v1=([0-9a-f]{64})", header or "")
    if not m or abs(time.time() - int(m.group(1))) > 300:
        return False
    want = hmac.new(secret.encode(), m.group(1).encode() + b"." + raw, hashlib.sha256).hexdigest()
    return hmac.compare_digest(want, m.group(2))

<?php
function verify(string $raw, string $header, string $secret): bool {
  if (!preg_match('/^t=(\d+),v1=([0-9a-f]{64})$/', $header, $m) || abs(time() - (int)$m[1]) > 300) return false;
  $want = hash_hmac('sha256', $m[1] . '.' . $raw, $secret);
  return hash_equals($want, $m[2]);
}

狀態

錯誤

錯誤使用HTTP狀態碼和JSON主體：{ "error": { "code": "insufficient_balance", "message": "..." } }。返回錯誤的請求不會扣除餘額。
