Send Whatsapp Message via PHP Code

 

How to Send and Receive Messages in WhatsApp using PHP

In this tutorial you will see How to Send and Receive Messages in WhatsApp using PHP.

Prerequisite :-

# Chat-API Token , Refer : https://www.phphive.info/255/get-whatsapp-password/

PHP Snippet for Sending Messages
Docs : http://chat-api.phphive.info/docs#/message/sendTextMessageRequest

Code:

<?php

 

$chatApiToken = ""; // Get it from https://www.phphive.info/255/get-whatsapp-password/

 

$number = "919999999999"; // Number

$message = "Hello :)"; // Message

 

$curl = curl_init();

curl_setopt_array($curl, array(

  CURLOPT_URL => 'http://chat-api.phphive.info/message/send/text',

  CURLOPT_RETURNTRANSFER => true,

  CURLOPT_ENCODING => '',

  CURLOPT_MAXREDIRS => 10,

  CURLOPT_TIMEOUT => 0,

  CURLOPT_FOLLOWLOCATION => true,

  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,

  CURLOPT_CUSTOMREQUEST => 'POST',

  CURLOPT_POSTFIELDS =>json_encode(array("jid"=> $number."@s.whatsapp.net", "message" => $message)),

  CURLOPT_HTTPHEADER => array(

    'Authorization: Bearer '.$chatApiToken,

    'Content-Type: application/json'

  ),

));

 

$response = curl_exec($curl);

curl_close($curl);

echo $response;

Sample Output :

1 2 3 4 5 6 7

{    "error":0,    "response":{       "message":"Message sent successfully",       "messageID":"string"    } }

For Receiving Messages

Refer : http://chat-api.phphive.info/docs#/device/messagesRequest

Q : Is There any Daily Limit for Using this API ?

Ans : No! There’s No Daily Limit. But Spamming is Obviously not allowed. We are keeping records of IP’s, if we find someone Spamming our Service then that IP will be Banned.

Drawing driving route directions between two locations using Google Directions in Google Map Android API V2

by

Karthikeyan R

In this article, we will develop an Android application which facilitates users to tap two locations in the Google Map. On taping the second point, a driving route will be drawn in the Google Map Android API V2 using Google Directions API.

This application is developed in Eclipse (4.2.1) with ADT plugin (21.1.0) and Android SDK (21.1.0) and tested in a real device (Android 2.3.6  -  GingerBread ).

Get the API key for Google Maps Android API V2

We need to get an API key from Google to use Google Maps in Android application.

Please follow the given below link to get the API key for Google Maps Android API v2.

https://developers.google.com/maps/documentation/android/start

Add Android Support library to this project

By default, Android support library (android-support-v4.jar ) is added to this project by Eclipse IDE to the directory libs. If it is not added, we can do it manually by doing the following steps :

• Open Project Explorer by Clicking “Window -> Show View -> Project Explorer”
• Right click this project
• Then from popup menu, Click “Android Tools -> Add Support Library “

Update the layout file res/layout/activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context=".MainActivity" >

    <fragment

        android:id="@+id/map"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        class="com.google.android.gms.maps.SupportMapFragment" />

                            path.add(hm);
