SMTP протокол (E-mail)
Sending a message
Для отправки SMS необходимо послать e-mail на адрес
sendsend.smscentre.com с текстом в формате:
It is possible to use our SMTP server directly. Address: send.smscentre.com. Authorization is not required.
The message must be transmitted in plain text with the encoding specified, by default koi8-r. The encoding is set in the Content-Type header
(Content-Type: text/plain; charset="CHARSET"). The maximum email size is 100 KB.
If it is not possible to transmit the text of the message with "Content-Type: text/plain", it is necessary to enclose the text in special tags "[text]message text[/text]".
Description of the parameters passed to the Server :
|psw||Client Password (you can add or change it on this page).
|phones||The number or comma-separated or semicolon-separated list of mobile phone numbers in international format
to which the message is sent. Numbers can be passed without the "+ " sign.
If the number is passed without the " + " sign, it can be corrected by automatic formatting
and converted to the correct international format. Thus, some
errors when entering phone numbers can be corrected automatically.
To disable auto-correction, pass the number with the "+ " sign.".|
You can also send a message to a group of numbersby specifying a special code " G<номер группы>".
The message will be sent to all numbers belonging to this group. For an e-mail message, a list of recipients' e-mail addresses is transmitted
|mes||The text of the message being sent. The maximum size is 1000 characters. If
necessary, the message will be divided into several SMS messages sent to the subscriber and paid separately. Size of one
SMS – 160 characters in Latin or 70 characters in Cyrillic. When splitting a message into multiple SMS
messages, a header is added to each part to combine the parts into a single message on the recipient's phone, and the maximum length becomes
67 for Cyrillic and 153 for Latin letters. You can add comments to the message text
that are intended for the sender to view the history in the personal account.
|id||The message ID. Assigned by the Client. Serves for further identification of the message. If not specified, it will be assigned automatically. Not necessarily unique. The identifier is a 32-bit number in the range from 1 to 2147483647, or a string up to 40 characters long consisting of Latin letters, numbers, and symbols ."-_".
|sender||The sender's name displayed on the recipient's phone.
English letters, numbers, spaces, and some characters are allowed. Length – 11 characters or 15 digits.

will be sent to the subscriber when the time h1 occurs, if the current time falls in the interval from h1 to h2,
that message will be sent immediately, otherwise the message will be sent the next day when
the h1 time is reached. This function, for example, is useful in order to prevent subscribers from receiving SMS messages

- +m. Sets the relative time offset from the current time in minutes. The + character must be encoded as %2B in the http request.

If it is not possible to correct the text of a multi-line message, it is possible to enable a special mode for transmitting this type of message. To do this, pass a value equal to 2 in the test parameter.
The list parameter allows you to send multiple messages with different messages to multiple phones with a single
request. The messages in the request are assigned a single identifier. Some parameters (for example, subj, voice) are passed
at the end of the list message list via a line feed.
The parameters must go strictly in the specified order. Login, psw are required,
phones and mes. If some optional parameter is missing, then the colon must remain.
Example (<id><id>, field <time><time>,<tz><tz> and field <translate><translate>,<format><format>,<sender><sender>,<test><test> are not specified):
In the composite field <translate><translate>,<format><format>,<sender><sender>,<test><test>, any parameter can be omitted,

If an error was made in the parameters or any other error occurred, and the test parameter was requested
for a response, it will be as follows:
N – error number, can take the following values:
- ERROR = N (description) – for 1,2,4,5,9 errors;
- ERROR = N (описание), ID - <id сообщения> – для ошибок 3,6,7,8.
|1||Error in parameters.
|2||Invalid username or password. Also occurs when trying to send a message from an IP address that is not included in the list of allowed by the Client (if such a list was previously configured by the Client).
|3||Insufficient funds in Customer account.
|4||IP address is temporarily blocked due to frequent errors in the queries. read More
|5||Invalid date format.
|6||Denied message (by text or by sender name).
|7||Invalid phone number format.
|8||The message to the specified number can not be delivered.
|9||Sending more than one identical request for the transmission of SMS messages within minutes.
If the message is successfully accepted and the response request is requested, the test parameter returns a string of the following format:
- OK - <n> SMS, ID - <id>
<n><n> is the number of SMS sent, calculated as the number of SMS messages in the message multiplied by the number
<id> – the message ID sent by the Client or assigned automatically by the Server.
The server does not accept more than two identical requests for sending SMS messages within a
minute to protect against errors and loops in the Client-side program in order to reduce the load and not waste
the Client's funds, as well as to prevent multiple messages from being sent to the same subscriber.
The server also blocks sending more than 50 messages to one subscriber, which were sent with a break
between messages of less than 2 minutes, to protect against flooding and unnecessary debiting of funds from the Client's account,
since many operators do not pass a large number of messages to one subscriber in a short period of time.
To send an HLR request, use the normal SMS message sending command, specifying format as 3.
The <mes><mes> parameter with the message text is not used and can be empty.
The result of the request can be obtained via the HTTP protocol by automatically calling the handler, or you can independently request the status
of the sent SMS message with a special command. Since the HLR request is executed asynchronously, and the result may not return from the operator immediately,
it is important to make a loop of several iterations with falling asleep (the sleep command) when requesting the status independently.).
Function E-mail2smsIn the Client's personal account in "In the user settings" it is possible to specify a list of phone numbers to which
the text of emails sent to the address will be forwarded in the form of SMS messages
This function can be used, for example, to receive notifications to the phone about various events from
programs or Internet services, in which it is possible to specify only the E-mail address.
