Sending SMS Messages with EasySendSMS REST API
Sending SMS is one of the core functionalities of the EasySendSMS API. Here’s a detailed look at how to send SMS using the REST API.
API Endpoint for Sending SMS
The endpoint for sending an SMS is:
POST https://restapi.easysendsms.app/v1/rest/sms/send
Required Headers
Your API requests must include the following headers:
apikey: Your API key for authentication.
Content-Type: application/json
Accept: application/json
Request Body Schema
All SMS requests should use the application/json content type, and the request body should be formatted in JSON. The following parameters are required:
from: The sender's name or number. For numeric values, the max length is 15 characters. For alphanumeric values, the max length is 11 characters. If you want the sender's name to appear with a plus sign, prefix it in the request (URL encoded).
to: The recipient’s mobile number in international format, without the plus sign or leading zeros. You can send messages to multiple numbers by separating them with commas (maximum 30 numbers per request).
text: The message content. It can be plain text or Unicode, with a maximum length of 5 parts (concatenated messages).
type: The message type. Use 0 for plain text (GSM 3.38 encoding) and 1 for Unicode.
scheduled (optional): The scheduled date and time for sending the message in ISO 8601 format. The time is in UTC.
Example Request
Here’s an example of how to send an SMS using the API in Python:
python
import requests
headers = {
'apikey': 'YOUR_API_KEY',
'Content-Type': 'application/json',
'Accept': 'application/json'
}
data = {
"from": "YourSenderName",
"to": "12345678900,19876543210",
"text": "Hello, this is a test message!",
"type": "0"
}
response = requests.post('https://restapi.easysendsms.app/v1/rest/sms/send', headers=headers, json=data)
print(response.json())
Handling Responses
The API returns a JSON response indicating the success or failure of your request. The response will include message IDs for successful sends or error codes if the request fails.
Example Success Response:
json
{
"status": "OK",
"scheduled": "Now",
"messageIds": [
"OK: 69991a73-a560-429f-9c5a-3251dc1522bb"
]
}
Example Error Response:
json
{
"error": 4012,
"description": "Invalid mobile number."
}
Performing HLR Lookup Using EasySendSMS REST API
HLR (Home Location Register) lookup is used to verify the status of a mobile number, including whether it is active, its network operator, and whether it is currently roaming. This can help reduce SMS delivery failures.
API Endpoint for HLR Lookup
To perform an HLR lookup, send a request to:
POST https://restapi.easysendsms.app/v1/rest/hlr/query
Request Body Schema
The request body should be in JSON format and include the following parameter:
number: The mobile number(s) to be checked, formatted without the plus sign or leading zeros. You can check multiple numbers by separating them with commas (maximum 30 numbers per request).
Example Request
Here’s how to perform an HLR lookup in PHP:
php
<?php
$apiKey = "YOUR_API_KEY";
$url = "https://restapi.easysendsms.app/v1/rest/hlr/query";
$data = array(
'number' => '19876543210'
);
$options = array(
'http' => array(
'header' => "apikey: $apiKey\r\n" .
"Content-Type: application/json\r\n",
'method' => 'POST',
'content' => json_encode($data),
),
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { /* Handle error */ }
var_dump($result);
?>
Understanding the HLR Response
The response will provide details about the mobile number, including:
status: Whether the number is live or not.
country: The country of the mobile number.
operatorName: The network operator.
roaming: Whether the number is currently roaming.
Example Success Response:
json
{
"12345678900": {
"number": "12345678900",
"country": "United States of America",
"err_desc": "Live",
"operatorName": "First Communications",
"type": "Landline",
"mccmnc": "-",
"roaming": "False",
"err_code": "0",
"status": "Delivered",
"ported": "True"
}
}
Number Validation with EasySendSMS REST API
The Number Validation (NV) feature allows you to validate the format and status of a phone number before sending an SMS. This is especially useful for ensuring that messages are sent to valid and reachable numbers.
API Endpoint for Number Validation
To validate a number, use the following endpoint:
POST https://restapi.easysendsms.app/v1/rest/nv/query
Request Body Schema
The request body should include:
number: The mobile number(s) to be validated, without the plus sign or leading zeros. Multiple numbers can be separated by commas (maximum 30 numbers per request).
Example Request
Here’s how to perform number validation using the API in C#:
csharp
using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
class Program
{
static async Task Main(string[] args)
{
var client = new HttpClient();
client.DefaultRequestHeaders.Add("apikey", "YOUR_API_KEY");
var content = new StringContent("{\"number\":\"19876543210\"}", Encoding.UTF8, "application/json");
var response = await client.PostAsync("https://restapi.easysendsms.app/v1/rest/nv/query", content);
var responseString = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseString);
}
}
Analyzing the Validation Response
The validation response will include the status of the number, the country, the network operator, and other relevant information.
Example Success Response:
json
{
"results": [
{
"status": "VALID",
"country": "United States of America",
"iso3166_2": "US",
"cc": "1",
"netName": "",
"mcc": "310",
"mnc": "316",
"operator": "",
"type": "FIXED",
"netType": "",
"msisdn": "12345678900"
}
]
}
Best Practices for Using EasySendSMS REST API
To make the most of the EasySendSMS API, it’s important to follow best practices:
API Key Security: Keep your API key secure and never expose it in client-side code or public repositories.
Rate Limiting: Respect the API’s rate limits to avoid your requests being rejected. Implement a queuing system in your application to manage the rate at which requests are sent.
Error Handling: Implement robust error handling to manage different types of errors, such as invalid numbers, insufficient credits, or network issues.
Monitor Usage: Regularly monitor your API usage and SMS credits to avoid unexpected disruptions.
Use Valid Numbers: Validate phone numbers before sending SMS to reduce the number of failed deliveries.
