Sending an SMS message

To send an SMS, you need to call the GET or POST address method: https://smscentre.com/sys/send.php?login=<login>&psw=<password>&phones=<phones>&mes=<message>
To get the SMS cost, you need to call the GET or POST address method: https://smscentre.com/sys/send.php?login=<login>&psw=<password>&phones=<phones>&mes=<message>&cost=1
Description of the parameters passed to the Server :

OptionThe value
loginCustomer Login.
pswClient Password (you can add or change it on this page).
phonesThe 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 .
mesThe 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 Ц 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.
Additional options
idThe message ID. Assigned by the Client. Serves for further identification of the message. If not specified, it will be assigned automatically. Not necessarily unique.

This function, for example, is useful in order to prevent subscribers from receiving SMS messages at night.
  3. 0ts, where ts is timestamp, the time in seconds since January 1, 1970.
  4. +m. Sets the relative time offset from the current time in minutes. The + character must be encoded as %2B in the http request.

To be able to pass the pid and dcs parameters, you need to add a special combination "\n~~~\n" (line feed, 3 tilde characters, and again line feed) to the end of the binary message, and then the text "pid: value1, dcs: value2" with the exact preservation of spaces.

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, you must additionally pass the nl parameterequal to 1 in the request.

Server response and error codes

The server sends the response as a string:

If an error occurred, the response will be one of the following:

When fmt = 0:
  • ERROR = N (description) Ц for 1,2,4,5,9 errors;

  • ERROR = N (description), ID - <id сообщени€> Ц for 3 errors,6,7,8.
When fmt = 1:
  • 0,-N Ц for errors 1,2,4,5,9;
  • <id сообщени€>,-N Ц for 3 errors,6,7,8.
When fmt = 2:
  • For 1 errors,2,4,5,9:

    <result>
    <error>description</error>

    "id": <id сообщени€>
    }
N Ц error number, can take the following values:

9Sending more than one identical SMS message request or more than five identical requests to receive the cost of a message within a minute.
This error also occurs when you try to send fifteen or more requests simultaneously from different connections under the same username (too many concurrent requests).

If the request is processed successfully, a string of the following format is returned:
  • when cost = 0 and fmt = 0: OK - <n> SMS, ID - <id>

  • when cost = 1 and fmt = 0: <cost> (<n> SMS)

    }

  • when cost = 1 and fmt = 3:
    {
    "cost": "<cost>",
    "cnt": <n>
    }

  • when cost = 2 and fmt = 3:
    {
    "id": <id>,

    {
    "id": <id>,
    "cnt": <n>,
    "cost": "<cost>",
    "balance": "<balance>"
    }

  • when op = 1 and fmt = 0 or 1, the information is added to the end of the normal output from a new line:
    <phone>,<mccmnc>,<cost>,<status>,<error>

  • when op = 1 and fmt = 2, an array is added to the response:
    <phones>
    <phone mccmnc="mccmnc" cost="cost" status="status" error="error">phone</phone>
    ...
    </phones>

  • when op = 1 and fmt = 3, an array is added to the response:

    "phone": "<phone>",
    "mccmnc": "<mccmnc>",
    "cost": "<cost>",
    "status": "<status>",
    "error": "<error>"
    },
    ...
    ]

Where:
<n><n> is the number of SMS sent, calculated as the number of SMS messages in the message multiplied by the number of recipients.
<id> Ц the message ID sent by the Client or assigned automatically by the Server.
<cnt> Ц the number of parts (when sending an SMS message) or the number of seconds (when sending a voice message (call)).
<balance> Ц new Customer Balance.
<phone> Ц phone number.
<mccmnc> Ц the numeric code of the subscriber's country plus the numeric code of the subscriber's operator.
<cost> Ц the cost of SMS-messages.
<status> Ц sMS Message status code.
<error> Ц error code in the status.

The server does not accept more than one identical request 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 spend 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 60 seconds, 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.
