Integration with the service (API)

The API allows you to send messages through your projects and services over the HTTP/HTTPS, SMTP, and SMPP protocols. Ready-made libraries in different programming languages connect to your project and help you send messages from anywhere with a single command.

Sending an SMS message

To send an SMS message, use the SUBMIT_SM command according to the specification.

The following encodings are supported:
  • 7-bit GSM for Latin text with support for European characters − (coding = 0);
  • 8-bit ISO-8859-1 (ASCII) for Latin text or binary data − (coding = 1);
  • UCS2 (UCS-2BE or UTF-16BE) for national alphabets (for example, Russian) − (coding = 2).
The coding field is encoded by two bits in the composite data_coding field, so data_coding = coding * 4.

To use the ISO-8859-1 (ASCII) encoding instead of GSM when connecting, you need to specify:
system-type = "ISO"
You can add comments to the text of the SMS message , which are intended for the sender to view the message history in the personal account.

The SUBMIT_MULTI command for multiple mailing is not yet implemented.

The server does not accept more than one identical request to send 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 one subscriber.

The server also blocks sending more than 50 messages to one subscriber, which were sent with a break between messages of less than 30 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.

When sending a composite message, all SMS parts must be transmitted to the server within a minute. Otherwise , the operator may reject the message, since to check for filters and templates, all SMS parts must first be glued together, and most operators wait no more than a minute.
