You can send an SMS by calling the URL in your browser or by submitting automatic HTTP-requests at the URL: 

http://www.sms4.de/cgi-bin/sms_out.pl
The following CGI-parameters are processed:

 

1.) Parameters for text-SMS

If you do not have access yet, please register here.

Sample request Text-SMS (GET)

The HTTP request must be URL-encoded. For example don´t use Ä but %C4 etc.
You can see the complete list here: urlencode-chart.
There are appropriate functions for url encoding in PHP, Perl and most other programming languages.
In PHP you can use fopen(), in Perl module HTTP::Request (read more in examples).

Line breaks in the text can be generated with %0A in the URL-String.
The parameters can be submitted using GET or POST.

 

 

Statuscodes

If the request was delivered successfully to our gateway, you get the following HTTP response: 

<smsout>
  <status>0</status>
  <statustext>SMS erfolgreich versendet</statustext>
</smsout>
or in extended format with v=1: 
<smsout>
  <status>0</status>
  <statustext>SMS erfolgreich versendet</statustext>
  <smsid>123456789</smsid>
</smsout>
or with displayed account balance guthaben=1: 
<smsout>
  <status>0</status>
  <statustext>SMS erfolgreich versendet</statustext>
  <guthaben>23.35</guthaben>
</smsout>
Defined statuscodes: 
 0 = SMS erfolgreich versendet
10 = Falsche Authentifzierung, Ungueltige Kombination User/Passwort/Kundennummer
11 = Falsche Authentifzierung, User fehlt
12 = Falsche Authentifzierung, Passwort fehlt
13 = Falsche Authentifzierung, Kundennr fehlt
20 = Handynummer fehlt
21 = Ungueltige Handynr
22 = Handynummer zu kurz
23 = Handynummer zu lang
25 = SMS Text fehlt
30 = Ungueltiger Tarif
31 = Ungueltige Kombination Tarif/Handynummer
40 = Test SMS aufgebraucht
41 = Guthaben aufgebraucht
42 = Monatslimit erreicht
51 = Ungueltige Absenderkennung
52 = Absenderkennung zu kurz
99 = Stoerung beim SMSC
