API access

sub personalized template variable allows each recipient to receive customized email content based on their specific replacement value.

x_smtpapi = {
	"to": ["d@163.com", "i@163.com"],
	"sub": {
		"%name%": ["jack", "rose"],
		"%money%": ["199", "299"]
	}
}

params['xsmtpapi'] = simplejson.dumps(x_smtpapi)

pubsub common template variable, all recipients receive the same replaced content

x_smtpapi = {
    "to": ["d@163.com", "i@163.com"],
    "pubsub": {
        "%productName%": "huawei watch",
        "%discountedPrice%": 1989.0,
        "%discount%": "8.5"
    }
}

#OR:
x_smtpapi = {
    "pubsub": {
        "%productName%": "huawei watch",
        "%discountedPrice%": 1989.0,
        "%discount%": "8.5"
    }
}

params['xsmtpapi'] = simplejson.dumps(x_smtpapi)

Note: Pubsub has a higher priority than sub. If both Pubsub and sub are passed simultaneously, sub will be ignored.

SMTP access

x_smtpapi = {
	"to": ["d@163.com", "i@163.com"],
	"sub": {
		"%name%": ["jack", "rose"],
		"%money%": ["199", "299"]
	}
}

#OR：
x_smtpapi = {
    "to": ["d@163.com", "i@163.com"],
    "pubsub": {
        "%productName%": "huawei watch",
        "%discountedPrice%": 1989.0,
        "%discount%": "8.5"
    }
}

#Custom header
msg['SC-Custom-key1'] = "value1"; 
msg['SC-Custom-key2'] = "value2";

msg['X-SMTPAPI'] = Header(base64.b64encode(simplejson.dumps(x_smtpapi)))

The SMTP server will check the format of the header field with the key of X-SMTPAPI in the email. If it doesn't meet the above requirements, an xsmtpapi error will be reported.
It should be noted that:

1. When making an SMTP call, X-SMTPAPI must be the last header field. Otherwise, it may lead to an xsmtpapi error.
2. When making an SMTP call, X-SMTPAPI must be encapsulated in base64 encoding. Otherwise, after a successful SMTP request, it will be intercepted by SendCloud during delivery and judged as an invalid email - a worker:invalid XSMTP - API error.
3. When making an API call, simply pass in a JSON string without base64 encoding encapsulation.
4. The total length of X-SMTPAPI cannot exceed 1M.
5. If a customer wants the data from the WebHook to include information embedded in the email, they can add a custom header during SMTP sending. The Key should start with "SC-Custom-", and this Key:Value will be returned to the user through the WebHook. The Key:Value should be a string.
6. Pubsub has a higher priority than sub. If both Pubsub and sub are passed simultaneously, sub will be ignored.

The structure and use of the JSON string encapsulated by value are shown below :

to Contains an array of recipient addresses to specify the recipients of the message.


    {
        "to": ["ben@ifaxin.com", "joe@ifaxin.com"]
    }

Attention:

to here will override the recipient parameter to
The number of to recipients here cannot exceed 100

Sub is an associative array its key is a variable' and value is a 'replacement value array'

Usage explanation: each "variable" corresponds to a "replacement value array". When replacing the contents of e-mail, each "Recipient" replaces the value of "variable" with the corresponding value in the "replacement value array" according to its position in the "recipient array"

Example :


# Email content

Dear %name%:

    Hello! Your consumption amount in ifaxin this month : %money% .

#---------------------------------------------------

# X-SMTPAPI

{
"to": ["ben@ifaxin.com", "joe@ifaxin.com"],
"sub":
{
"%name%": ["Ben", "Joe"],
"%money%":[288, 497]
}
}

#---------------------------------------------------

# ben@ifaxin.com will receive:

Dear Ben:

    Hello! Your consumption amount in ifaxin this month: 288 .

#---------------------------------------------------

# joe@ifaxin.com will receive:

Dear Joe:

    Hello! Your consumption amount in ifaxin this month: 497 .

apps Tracking items and switches during sending “apps” is an associative array that contains a set of app names (unsubscribe, open, click) and their settings. These settings will override the settings in the user's account. The enable parameter can only take effect when the tracking domain is successfully configured.


x_smtpapi =
{

    "to": ["xxx@qq.com"],
    "sub": {"%name%": ["Joe"]},
    "filters": {
    "subscription_tracking": { # Unsubscribe tracking
    "settings": { "enable": "1" }
    },
    "open_tracking": { # Open tracking
    "settings": { "enable": "1" }
    },
    "click_tracking": { # Click tracking
    "settings": { "enable": "1" }
    }
    }
}

page_id The unsubscribe page specified during sending

Explanation of usage:

The "page_id" corresponds to the ID field of a specific unsubscribe page created under "Unsubscribe Settings" - "Unsubscribe Page" in the "Sending Settings" of the Aurora SendCloud console.
Customers need to create an unsubscribe page in advance in the Aurora SendCloud console before they can set the "page_id" to the corresponding ID during sending.
When sending, pass the parameter "page_id" and set the value to the ID of a certain unsubscribe page. At this time, both the unsubscribe link and the unsubscribe page will be in the configured language and style.
The priority of passing the "page_id" parameter is higher than the default unsubscribe page setting corresponding to the API_USER during sending.
An array form is supported to specify the unsubscribe page, and the number of elements in the array needs to be the same as the number of "to" in x_smtpapi. The position of the element in the array corresponds one - to - one with the position of each "recipient" in the "recipient array". If the number of elements in the array does not match the number of "to", the default "page_id" of the customer under this apiUser will be used instead.

Example :

x_smtpapi =
{
    "to": ["xxx@qq.com"],
    "sub":{"%name%": ["Joe"]},
    "settings": 
    {
        "unsubscribe": 
            {"page_id": 562}
    }
}

send_domain The sending domain name specified during sending

Explanation of usage:

Contact the customer service to activate relevant permissions before using this extended field.
The domain name passed as send_domain should be added in advance on the "Settings" - "Domains" page in the Aurora SendCloud account and configured to pass as required.
Customers can use the same API_USER. By means of the send_domain field, they can make emails be sent from the domain name specified by the customer.
If customers pass in the send_domain field when sending emails, the sending resources and settings configured for that domain name will be used for scheduling. See the following example:


x_smtpapi = 

{
    "send_domain":"customer.domain.com"
}
