Request Parameters

The parameters are applicable for POST and GET requests.

Parameter	Required	Type	Description
clientId	yes	string	Subscriber’s phone number, no more than 25 characters. More details Examples: 79036550550, +79036550550, 8-903-655-05-50, 89036550550.
message	yes	string	Message to send to the subscriber. More details To send in this parameter: for the GET method, the text must be encoded in UTF-8 while sending a text message; for the POST method, the text must be encoded in UTF-8, which is specified in the request header. Maximum allowed message length for SMS: 2000 characters. Important When sending SMS messages with the flash attribute set the message length should not be more than 70 characters (for Cyrillic text) or 140 characters (for Unicode text).
serviceId	yes	string	ID of the Partner’s service (login), which is used to send a message. More details The Service Provider establishes serviceId while enabling the Partner’s service and reports it to the Partner.
pass	yes	string	Password for authorization in the service. More details The Service Provider establishes the password while enabling the service and reports it to the Partner.
ptag	no	string	Message identifier in the Partner’s system. More details It may contain from 1 to 50 characters. Valid characters: 0...9a...zA...Z- It may be any identifier in the Partner's system. Note For example, it may be the unique identifier of a message or the identifier of subdivision, which initiates the request for sending. In contrast to the partnerMsgId parameter, which is needed to control resending and duplication, the Service Provider does not control values sent in the ptag parameter (only format compliance is checked). The Service Provider optionally returns this identifier to the Partner as part of the request for receiving the message delivery status (this functionality is described in the section Delivery Status Service).
sending_time	no	string	Local time to send a message to a subscriber. More details Specified in the hh_hh format, where two hour values specify the time period in which the message should be sent. Warning If the parameter is specified, then its value cannot be empty. Note For example, if the parameter value is sending_time = 10_20, the message will be sent within the period from 10:00 to 20:00 local time in the time zone of the subscriber. The time zone of the subscriber is determined not by actual location of the subscriber. If the Partner doesn't send the time_zone parameter, the time zone of the subscriber will be determined by the phone number. If the Partner sends the time zone in the time_zone parameter, the message will be sent to the subscriber according to local time of this time zone.
time_zone	no	string	Time zone of the subscriber. More details Specified in the ±hh:mm format. For details see ISO 8601. If the Partner sends the value time zone in this parameter, the message will be sent to the subscriber according to local time of this time zone, otherwise the time zone of the subscriber will be determined by the subscriber's phone number. Note The subscriber with the number from Khabarovsk is in Moscow. The following sending options are available: The values are received: sending_time = 10_20, time_zone = +04:00 (Moscow time). The message will be sent within the period from 10:00 to 20:00 Moscow time. The sending_time = 10_20 value was received and the time_zone parameter wasn't passed. The message will be sent within the period from 10:00 to 20:00 (Khabarovsk time). For the zero zone it is necessary to specify a "+" or "–" sign. The "+" sign will be transformed into %2B when encoded in URL. For example, the +04:00 time zone will be sent as time_zone = %2B04:00.
flash	no	string	Attribute of sending Flash-SMS. More details If flash = 1, Flash-SMS will be sent to the subscriber. If the parameter is missing or not equal to 1, a common SMS message will be sent. The maximum length of SMS messages with the flash attribute set: 70 characters (for Cyrillic text); 140 characters (for unicode text).
source	no	string	Service name of the sender. More details This parameter is optional. If the parameter is missing in the request, the message will be sent to the subscriber from the default service name (setting on the Service Provider's side). Important This parameter is not available for the Partner by default. This feature can be activated only after approval by the Service Provider. In this case, the list of allowed sender names is set for the Partner's service or the dynamic signature feature is activated.
output	no	string	Request response format. More details If output = xml, the response to request will be formed as XML, see Response in the XML Format. If the parameter is not defined or is different, the default format is used: text/plain (see Response to the request).
partnerMsgId	no	string	Message unique identifier in the Partner’s system. More details Allowed length: from 1 to 50 characters. This parameter is required for resending and duplicate control. The Partner can send a request to send a message several times with the same partnerMsgId. In this case: the message will be sent to the subscriber only once (when the first request is received); in responses to requests the Service Provider will return to the Partner the same message identifier in the Service Provider system (the same that was sent for the first request). The Service Provider as an option returns this identifier to the Partner as part of the request for receiving the message delivery status (see section Delivery Status Service). This parameter is not available by default. To enable this functionality, please consult with your manager.
smsPriority	no	integer	Parameter indicates the priority of the message. More details Messages with a higher priority are sent to the operator first. Possible values: 0 is the lowest priority; 1 is a normal priority; 2 is a high priority. This parameter is not available by default. The connection of this functionality should be agreed with your supervising manager.
shortenLinks	no	boolean	Parameter controls the automatic shortening of long links in the message. More details Important It is used for single messages only. If cascade resending, you need to use the shorten_list parameter (see Cascading Message Sending). Important This option is not available by default. The connection of this functionality should be agreed with your supervising manager. For more details: see Link Shortening Service.

Requests with Binary Data

When transmitting binary data, a sequence of bytes in the hexadecimal number system is transmitted in the message text.

To send binary data in a POST or GET request, you need to indicate additional parameters specified in the table below.

Request Examples

}

Parameters for Binary Data

Parameters for binary data sending in a request.

Parameter	Required	Type	Description
message	yes	string	Message to be sent to the subscriber. More details When sending binary data, the parameter contains a sequence of bytes in hexadecimal representation (standard HEX Decimal). Other characters in the text is unacceptable. To send a binary SMS message, the text must be in UTF-8 encoding. Maximum allowed message length for SMS: 2000 characters.
smpp_encoding	no	integer	Interpretation of data More details For the correct delivery of a binary SMS message additional parameters in the request must be transmitted that ensure the correct interpretation of the data after sending using the SMPP protocol version 3.4. For certain types of messages, one of the parameters (or both at the same time) is specified. Many of the values for these parameters are specified by SMPP version 3.4 in sections for the smpp_encoding and smpp_esm_class parameters. When sending a binary message to a subscriber, the specified values of the smpp_encoding and smpp_esm_class parameters are put in all its parts. If none of the smpp_encoding and smpp_esm_class parameters are specified, the message will be processed as the text message.
smpp_esm_class	no	integer

Response

After receiving and processing the request, the Service Provider synchronously returns the response to the Partner.

By default, the response from the Service Provider comes in the text/plain format.

In agreement with the Partner, the response can be generated in XML format.

Note

The Service Provider sends messages to subscribers only if the request is successfully processed.

Response exampleError codes when sending the request

An example of an error response – invalid serviceId/pass combination:

{
    Invalid password
}
