Mandrill 的 Render API 会忽略映射到 Handlebars 变量的 merge_vars 吗?

Does Mandrill's Render API ignore merge_vars that map to Handlebars variables?

Mandrill 的 Template API page, I plug in the following JSON to test the Render 方法点击 "Try it":

{
    "key": "MY VALID KEY",
    "template_name": "test1",
    "template_content": [

    ],
    "merge_vars": [
        {
            "name": "invoice_number",
            "content": "1001"
        }
    ]
}

测试结果与我的模板一起返回,但我正在测试的 merge_var 尚未合并,即结果仍然包含 {{invoice_number}}:

{
    "html": "<p style=\"font-family: sans-serif;\">Dear Customer,</p>\r\n\r\n<p style=\"font-family: sans-serif;\">Invoice {{invoice_number}} ...</p>"
}

Mandrill 的 Render API 会忽略映射到 Handlebars 变量的 merge_vars 吗?

根据 Mandrill 的支持:

As you noticed, the render API call does not currently support Handlebars templates. While I can't provide an exact ETA for when the render API call will work with Handlebars, I can tell you that it's something that our developers are working to extend support for very soon.

I would suggest keeping an eye on our Mandrill API Documentation as that support will be noted there as an additional parameter for the call as soon as it is supported.
