通过本教程可以快速上手Wyre MassPay API.
什么是MassPay?

客户可以使用MassPay在不同货币间转账。如果您有跨国转账汇款的需求，MassPay是您的首选。

目录：

  1. 开设Wyre账户
  2. 发送API请求
  3. 创建第一笔转账请求
  4. 转账示例
  5. 代码示例
  6. 相关链接和联系方式

1. 开设Wyre账户

首先，如果您没有账户，需要创建一个账户。这个过程中需要核对email和手机号。
开始转账前您需要有以下的信息：

  • API Key
  • SECRET Key
  • ACCOUNT ID

这些信息可以在登陆后的Your Account | API Keys里找到。
当生成一个API key后，页面显示如下图。

494

最后还需要AccountID。可以从key的details链接里找到。

667

注意
请不要包含"account:"字符串。
例如：account:pm9ddj8jr8rrq53fsk9v4bfhunieu72t应为pm9ddj8jr8rrq53fsk9v4bfhunieu72t。

2. 发送API请求

Wyre API文档链接为https://api.sendwyre.com/v2/。返回格式为JSON。
Wyre利用如下的HTTP头字段作为安全措施。

头字段描述
X-Api-Key您的Wyre API key
X-Api-Signature用secret key计算得到的密钥散列消息认证码

计算您的密钥散列消息认证码的步骤如下（代码示例在页底）：

  1. 在请求URL后加上毫秒时间戳。例如为了得到账户细节，请求URL为https://api.sendwyre.com/v2/account?timestamp=1426252182534。
  2. 将请求的URL和HTTP请求内容合并成一个UTF-8字符串。GET请求内容为一个空字符串。
  3. 用SHA-256和您的API Secret Key计算签名。
    以下是Wyre MassPay API节点。点击名称链接进入相应文档。
名称API节点HTTP方法描述
账户详情https://api.sendwyre.com/v2/accountGET账户详情包括联系方式，所有货币的结余，相关授权和支付方式。
实时价格https://api.sendwyre.com/v2/ratesGET不同交易所的比特币价格。
创建转账https://api.sendwyre.com/v2/transfersPOST创建两种货币间的转账。目的地可以是email地址，比特币钱包地址或者银行账户。可以开启自动确认功能，但并不推荐。
转账确认https://api.sendwyre.com/v2/transfer/:transferId/confirmPOST转账只会在您确认所有细节之后的30秒内执行。
转账状态https://api.sendwyre.com/v2/transfer/:transferIdGET如果您不想用callbackUrl，您可以通过本API获得订单状态。不同订单状态种类在这里。

创建第一个转账请求

一个转账请求是一个包含最多7个字段的JSON POST请求。

  • sourceAmount - 只需要选择 sourceAmount 或者 destAmount中一个。sourceAmount是从主账户中扣除的用来转账的金额。这种情况下您可以指定从账户中扣除的金额，入账金额将由交易费用和汇率确定。
  • sourceCurrency - 转出货币代码ISO 3166-1 alpha-3
  • dest - 转账地址。可以是email地址，电话号码，blockchain地址，或银行账户。
  • destAmount - 只需要选择 sourceAmount 或者 destAmount中一个。destAmount是将被转入目标地址的金额。sourceAmount可以由destAmount，交易费用和汇率计算出。
  • destCurrency - 转入货币代码。可以和转出货币代码不同。如果不同则汇率会被自动计算。
  • callbackUrl - 可选，Wyre返回转账状态的Url。
  • autoConfirm - 可选，默认自动确认转账的参数。不推荐。

以下例子将巴西雷亚尔转换为美元并发送到我们工程师的银行账户。

{
  "dest": {
    "paymentMethodType":"INTERNATIONAL_TRANSFER",
    "country": "US",
    "currency": "USD",
    "firstNameOnAccount": "Sam",
    "lastNameOnAccount":"Schlachter",
    "accountNumber": "1234dinosaur",
    "routingNumber": "0000000000",
    "accountType": "savings",
    "bankName": "Bank of 'murrrica",
    "bankStreet": "112 Brannan St",
    "bankCity": "San Francisco",
    "bankPostal": "94108",
    "accountHolderPhoneNumber": "+14102239203",
    "beneficiaryType": "INDIVIDUAL",
    "priority":"HIGH"
  },
  "sourceCurrency": "BRL",
  "destCurrency": "USD",
  "destAmount": 10,
  "message":"Here's your $10!"
}

返回值类似。最重要的返回值是id字段。我们用这个值确认转账并获取转账状态。

如果转账金额和汇率满足我们的要求，我们需要点击[转账确认]（或者用自动确认功能）来确认转账。

最后一步是从转账状态获取转账的状态--完成，过期，或者失败。或者你可以在callbackUrl字段填入一个URL。Wyre会将包含订单状态的HTTP POST请求发送到该URL。

以下是包含银行账户的转账示例。
