Integration with the service (API)

The API allows you to send messages through your projects and services over 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. For simplified authorization, instead of a login and password pair, you can use a special API key.

Managing message templates

To manage message templates, call the appropriate address with the required command and parameters using the GET or POST method.

To create a template: https://smscentre.com/sys/templates.php?add=1&login=<login>&psw=<password>&name=<name>&msg=<msg>
To change the template: https://smscentre.com/sys/templates.php?chg=1&login=<login>&psw=<password>&id=<id>
To delete a template: https://smscentre.com/sys/templates.php?del=1&login=<login>&psw=<password>&id=<id>
To get a list of templates: https://smscentre.com/sys/templates.php?get=1&login=<login>&psw=<password>
The following parameters are passed to the server:

Option	The value
login	Customer Login.
psw	Client Password (you can add or change it on this page).
apikey	A special API key used for simplified authorization instead of the "login+password" pair (you can create it on this page).
name	Template Name.
msg	The text of the message.
format	Message format: empty string – not specified. sms – SMS. flash – Flash-SMS. bin – Binary SMS. push – Wap-push. mms – MMS. call – Call. mail – E-mail. viber – Viber.
sender	Sender ID.
fl[1]	Use for auto-signing.

If an error occurs, the Server returns the following string:

when fmt = 0:
ERROR = N (description)
when fmt = 1:
0,-N
when fmt = 2:
<result>
<error>description</error>
<error_code>N</error_code>
</result>
when fmt = 3:
{
"error": "description",
"error_code": N
}

N – error number, can take the following values:

The value	Description
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	The record was not found.
4	The IP address is temporarily blocked.
5	Save or delete error.
9	Attempt to send more than three identical template action requests. 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 successful, the Server returns a response in the form of a string:

When creating a template:

when fmt = 0: ID - <id>
when fmt = 1: <id>
when fmt = 2:
<template>
<id>id</id>
</template>
when fmt = 3:
{
"id": <id>
}

When changing or deleting a template:

when fmt = 0, 1: OK
when fmt = 2:
<result>OK</result>
when fmt = 3:

{
"result": "OK"
}

When requesting a list of message templates:

when fmt = 0:
id = <id>, name = <name>, format = <format>, sender = <sender>, flag = <flag>, message = <message>
...
when fmt = 1:
<id>,<name>,<format>,<sender>,<flag>,<message>
...
when fmt = 2:
<list>
<template>
<id>id</id>
<name>name</name>
<format>format</format>
<sender>sender</sender>
<flag>flag</flag>
<message>message</message>
</template>
...
</list>
when fmt = 3:
[{
"id": <id>,
"name": "<name>",
"format": "<format>",
"sender": "<sender>",
"flag": <flag>,
"message": "<message>"
},
...]

Where:
<id> – the template ID assigned by the system automatically.
<name> – template Name.
<format> – message format.
<sender> – sender ID.
<flag> – flag for the template. Setting the first bit of the flag (fl[1]=1) assigns the use of the template for auto-signing.
<message> – the text of the message.

The server does not accept more than three identical requests for actions with templates within a minute to reduce the load and protect against errors and loops in the Client-side program.
