DecisionTelecom SMS API allows you to send SMS messages to any country in the world via API. Each message is identified by a unique random ID, so users can always check the status of a message using given endpoint.
The SMS API uses HTTPS with access key that is used as the API authorization. Request and response payloads are formatted as JSON using UTF-8 encoding and URL-encoded values.
API Authorization - Base64 access key.
Please contact your account manager to get an API key.

You can create analytics on your SMS traffic by using event-based webhooks — user-defined HTTP callbacks — to track the delivery status of outgoing messages.
For every SMS message you send, IT-Decision Telecom sends a status update to a URL you configure as a callback. You can store the information on your server for delivery status analysis. Upon one of these events, IT-Decision Telecom makes an HTTP request (POST) to an endpoint URL you’ve configured for the webhook. To handle a webhook, you must create a listener (web app) that can accept these HTTP requests from IT-Decision Telecom. IT-Decision Telecom automatically retries webhooks three times if an HTTP 200 status code is not returned:
Interval - 15 minutes, 12 hours , 1 day, If your URL is not available for the whole retry period, the data will be lost (Delivery Reports).

}
message_id int A unique random ID which is created on the DecisionTelecom platform.
Phones arrayThe telephone number that you want to do a network query on.
sender string The sender of the message. This can be a mobile phone number (including a country code) or an alphanumeric string. The maximum length of alphanumeric strings is 11 characters.
text string Each multi-part text message is limited to 153 characters rather than 160 due to the need for user-data headers (UDHs) information.( 306 (2x153 characters) ,459 characters (3 x 153)…)
Mobile phones use UDH information to enable them to link long messages together so that they appear as single SMS messages in recipient’s phone inbox. Using Unicode, for languages such as Hindi, restricts your message to a maximum of 70 characters per SMS .
The maximum lengths of two-part and three-part multi-part Unicode text messages are 134 (2 x 67) and 201 (3 x 67) characters, respectively.
part_count int Count of parts
concat_part int Part number
validity_period int SMS lifetime min 2 minute max 4320

SMPP SMS API
Short Message Peer-to-Peer (SMPP protocol)
Used to send and receive large volumes of SMS traffic. The SMPP protocol is especially popular among SMS providers and telecom operators.
Please contact one of our consultants to get the data for connecting via the SMPP protocol.
SMPP Server
Below you can find the data for connection to the DecisionTelecom SMPP server:
Host name port TLS port
web.it-decision.com 2888 2999
User name and password
Your account manager in DecisionTelecom will provide you with a username (system_id) and password. If you haven't received them yet, or if you still need to make a request, simply send us an email at support@it-decision.com; We will be happy to help you.
Bindings and throughput
Whenever an SMPP account is set up for you, you will get the required number of connections (binds) and throughput. In most cases these values will be 1 bind and 50 messages per second.
It is interesting to note that these values can be higher at the request of the client.
Security
If you are connecting to any server via a TLS connection, be sure to select TCP port 2999. Also be aware that servers only accept methods SSLv1, SSLv2 and SSLv3.
Bind PDU
The bind_receiver, bind_transceiver, or bind_transmitter SMPP PDU request has a fixed set of fields. Most of the fields don't matter to us; in fact, we only read the system_id, password, and interface_version fields, and ignore the rest.
Interface_version
The DecisionTelecom SMPP server supports SMPP protocol version 3.4. Be aware that if you configure your SMPP client for version 3.3, you will miss out on some features, primarily the TLV information in the Deliver_sm PDUs.
Submit_sm PDU
You can use the submit_sm PDU to send us your messages. The submit_sm PDU request also has a couple of fields that are not used by our platform and can be safely ignored.
Data_coding
The values of the data_coding field are not explicitly declared in the SMPP specification, so each SMPP server is required to give its own definition. Below is a list of data encodings that we accept as input.
