Sending Whatsapp Messages

Textly also allows you to send text messages via whatsapp to one or more targets which you can do by dispatching a post request to /api/v1/client/whatsapp/send_plain

TypeScript

const myApiToken = await getApiToken(); // See authentication guide to learn how to get a token

const response = await fetch(
  "https://api.textly.ly/api/v1/client/whatsapp/send_plain",
  {
    method: "POST",
    headers: new Headers({
      "Content-Type": "application/json",
      Authorization: `Bearer ${myApiToken}`,
    }),
    body: JSON.stringify({
      target_numbers: ["09100000"],
      content: "Hello world",
      wait_for_send: true,
    }),
  }
);

PHP (Laravel)

use Illuminate\Support\Facades\Http;

$token = getApiToken();

$response = Http::withHeaders([
  "Authorization" => "Bearer $token"
])->post('https://api.textly.ly/api/v1/client/whatsapp/send_plain', [
    "target_numbers" => ["09100000"],
    "content" => "Hello world"
    "wait_for_send" => true,
]);

Curl

$ curl -X POST https://api.textly.ly/api/v1/client/whatsapp/send_plain \
     -H "Content-Type: application/json" \
     -H "Authorization: Bearer <YOUR API TOKEN>" \
     -d '{
           "target_numbers": ["09100000"],
           "content": "Hello world",
           "wait_for_send": true
         }'

VB.NET

' Required Imports
Imports System
Imports System.Net.Http
Imports System.Net.Http.Headers
Imports System.Text

Private Sub SendSms()
    Using client As New HttpClient()
        client.DefaultRequestHeaders.Authorization = New AuthenticationHeaderValue("Bearer", "<api-key>")

        Dim requestBody As String = $"{{""target_numbers"":[""<phone-number>""],""content"":""test"",""wait_for_send"":true}}"
        Dim content As New StringContent(requestBody, Encoding.UTF8, "application/json")
        Dim response As HttpResponseMessage = client.PostAsync("https://api.textly.ly/api/v1/client/whatsapp/send_plain", content).Result

        Console.WriteLine(response.Content.ReadAsStringAsync().Result)
    End Using
End Sub

C#

using System.Net.Http.Headers;
using System.Text;
using System.Text.Json;

string token = "<your-api-key-here>";

using (HttpClient cl = new HttpClient())
{
    cl.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
    cl.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

    var requestBody = new
    {
        target_numbers = new[] { "<number1>", "<number2>" },
        content = "Hello world",
    };

    var json = JsonSerializer.Serialize(requestBody);
    var content = new StringContent(json, Encoding.UTF8, "application/json");

    HttpResponseMessage response = await cl.PostAsync("https://api.textly.ly/api/v1/client/whatsapp/send_plain", content);

    if (response.IsSuccessStatusCode)
    {
        Console.WriteLine("Message sent successfully.");
    }
    else
    {
        Console.WriteLine($"Error: {response.StatusCode}");
    }
}

As we can see from the code snippet the /api/v1/client/whatsapp/send_plain expects a json body that contains

{
  "target_numbers": ["09100000"],
  "content": "4501",
  "wait_for_send": true
}

• Target_numbers: an array of phone numbers which the message will be sent to (must contain at least one number)
• content: is the content of the text message
• wait_for_send: whether or not to immediately send the message or have it be scheduled to send 3 to 5 seconds (optional)
