SMS Gateway Developers' API

1.0 Introduction

This document describes how to programmatically interact with the SMS server (You should have registered, and created a sub-account that you'll use for accessing this API ).
NEWS!: You can now access the API functions directly on your main account (rather than creating sub-account), to do this, replace the sub-account name with 0, and replace sub-account password with your main account password.
Typical credentials as follows:
sub_account: 001_0
sub_account_pass: MyMainPa$$

Interaction of this sort might be useful to those desiring to automate SMS sending, fetch the information about sent messages, or pull SMS log into a third party program.
This document is intended to be utilized by technical personnel with programming knowledge; specifically with a working knowledge of HTML forms and JSON.

NOTE: Examine your automation program closely for problems. You are just as responsible for the SMS commands initiated by an automation program as if you had performed the action manually.

1.1 Automation Details

In the following sections, you will find the parameters for using the API and some sample codes.
All API request must be sent to http://cheapglobalsms.com/api_v1 via HTTP POST or GET method and the response will be returned in a JSON format.

NOTE: If for any request, the error key is present in the JSON response, then the process was NOT successful, and the value of error key is the description of what went wrong.

2.0 SMS Automation

This section describes how you can automatically send SMS, fetch SMS information and delivery statistics, stop / delete SMS / get total units spent or get the balance and other information of the sub-account.

2.1 Sending SMS

The following parameters can be sent, through HTTP GET or POST request to the URL: http://cheapglobalsms.com/api_v1

Input Field Name Description Example Value
sub_account A sub_account name that you have created 001_mysub1
sub_account_pass Sub account password pa55w0Rd
action The value for this key must be send_sms send_sms
message The message to be sent. Hello, there will be a meeting today by 12 noon.
recipients The recipient's phone numbers. Multiple numbers can be separated by comma (,).
Any mobile numbers starting with zero will have the zero stripped and replaced with the sub-account's default dial code.
If the mobile number does not start with a zero, the default dial code will not be applied.

E.G if the sub-account's default dial code is '+234',
08086689567,+2348094309926,4478128372838 will be converted to, 2348086689567,2348094309926,4478128372838 		+2348094309926
Optional Fields
type 0 means normal sms, while 1 means flash-message.
If this was not supplied, the message will be assumed to be normal SMS. 		0
unicode 0 means non-unicode sms, while 1 means that the message contains some special characters (e.g chinese, korean,...) that must be preserved (hence the character encoding of the HTTP request is also UTF-8)
Please note that when a message is in unicode format, the character limits of the messages reduces to 72 characters per page. 		0
route 0 means standard route, 1 means financial route, 2 means corporate route TIPS: TIPS: While using CORPORATE ROUTE helps your budget (economizing by sending through standard channel if the destination has already been found to be unrestrictive). FINANCIAL ROUTE doesn't do such fallback (typically used for OTP/Transactional messages). 0
sender_id What will appear to the recipient as the sender of the SMS. 3 to 11 characters (or 3 to 14 digits if numeric).
If this was not supplied, the sub-account's default sender_id will be used. 		President
default_dial_code The number that will replace the leading-zero on the recipient's phone number.
If this was not supplied, the sub-account's default_dial_code will be used. 		234
send_at The message will be on queue, to be sent on the specified date.
If this was not supplied, or if the value is a past date, the message will be sent immediately. 		2016-04-22 13:45
or
2016-04-22
or
13:45
timezone_offset The timezone to be used for send_at.
If this was not supplied, the sub-account's timezone_offset will be used. 		+1
contact_groups Includes all numbers from the supplied contact groups of the sub-account with the recipients default,My Customers
ignore_groups Excludes all numbers that appears in supplied contact groups of the sub-account from the recipients My Customers,My Customers2
contacts A JSON Array of contacts, E.G:
[{"phone":"+2348093216754","firstname":"Pearl"},{"phone":"08086689567","firstname":"Ibukun","lastname":"Oladipo","group_name":"Client","extra_data":"USER001"},{"phone":"+2348094309926","override_message":"Hello, bro. Please be around before 11:00am","override_date_time":"2016-04-22 09:30"}]
** 'phone' is the only compulsory field in a contact, when sending contacts in JSON format.
** If you include 'override_message' in a contact when sending message, it is the override_message that will be sent to that contact instead of the original message.
** If you include 'override_date_time' in a contact, message will rather be sent to the contact at the supplied override_date_time.
** If you include 'extra_data' (maxmum of 60 characters) in a contact when sending message, the value of the extra_data you supplied will be available in the record of the message when you later fetch_sms.
save_as If this is supplied, the recipient phone number(s), will be saved under the group-name; specified as the value of this field, otherwise the numbers will not be saved to contacts default
callback_url If a url-encoded, valid url is specified, the delivery report will be sent as an encoded string of JSON Array, in an HTTP POST request to this supplied URL; under a POST key 'result'. (typically $_POST['result'] in php)
Sample format of the JSON string posted to the callback_url: 
[
                {
                "sms_id":"137072",
                "batch_id":"1_1_1462391634",
                "units":1,
                "pages":1,
                "status":2,
                "status_msg":"DELIVERED",
                "info":"Message delivered to handset",
                "extra_data":""
                },...
            ]
 http%3A%2F%2Fcheapglobalsms.com%2Fprocess_sms_callback
NOTE: All duplicate numbers will be automatically removed for you and SMS will be sent to unique recipients only.
