This article illustrates how to set up your application to send Whatsapp messages via Elipse E3\/Power.<\/p>\n

First of all, you will need to know that WhatsApp, a free messaging and calling app, provides an API REST with JSON data formar; this API is what allows receiving and sending messages from your WhatsApp account.<\/p>\n

The API follows the default HTTP standard, based on request and response.<\/p>\n

<\/h2>\n

API do WhatsApp<\/b><\/h2>\n

1.<\/strong> Firstly, you must access<\/a> the WhatsApp API connecting the phone to the service:<\/p>\n

\"\"<\/p>\n

This access is free for the first three days<\/strong>. After this, you will need to purchase a service plan.<\/p>\n

2.<\/strong> Then, create your account and log in to it:<\/p>\n

\"\"<\/p>\n

3.<\/strong> On the Chat API panel, you will need to authorize using the API via WhatsApp Web. To do so, you will receive a QR code on the main page of your personal account.<\/p>\n

Then, follow the instructions and open WhatsApp on your phone, access \u00abSettings\u00bb -> WhatsApp Web -> Digitalize QR code.<\/p>\n

\"\"<\/a><\/p>\n

4.<\/strong> After reading the QR code, the authentication status will be displayed as “authenticated”, and you will see the URL and API token for using it with Elipse E3.<\/p>\n

\"\"<\/a><\/p>\n

5.<\/strong> To send a test message, access\u00a0 API Docs<\/strong> on the Admin panel and select\u00a0 \u201cPOST <\/span>\/sendMessage Send a message to a new or existing chat<\/span>\u201d<\/em>. Then, click \u201cphone\u201d, fill out phone *<\/strong> and body * <\/strong>parameters, and after that click\u00a0 SEND. The Request URL<\/strong> field displays the url that must be used at the http request\u00a0 http (POST) via Elipse E3.<\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

6.<\/strong> Then, you will receive the response to the send request:<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

<\/h2>\n

Using WhatsApp with Elipse E3\/Power<\/strong><\/h2>\n

1.<\/strong> To write the API, you will use the\u00a0 ServerXMLHTTP <\/strong>object, which supplies methods and properties that allow establishing an HTTP connection between files or objects in different web servers. The script below was used for sending messages to the desired phone number:<\/p>\n

Sub CommandButton1_Click()\r\n  ''' The first parameter is the recipient's number, including the country code.\r\n  ''' The second paramter is the content of the message.\r\n  number = Screen.Item(\"spNumber\").Value\r\n  msg = Screen.Item(\"spMessage\").Value\r\n\r\n  WhatsAppMessage_Send number, msg   \r\nEnd Sub\r\n\r\nfunction WhatsAppMessage_Send(strNumber, strMessage)\r\n  \r\n API_URL = \"https:\/\/api.chat-api.com\/instanceXXXXX\/sendMessage?token=1cwm5fzehdrmvowc\"\r\n strJson = \"{\"\"phone\"\": \"\"\" & strNumber & \"\"\", \"\"body\"\": \"\"\" & strMessage & \"\"\"}\"\r\n    \r\n   Set oHttp = CreateObject(\"Msxml2.ServerXMLHTTP\")\r\n   oHttp.Open \"POST\", API_URL, False\r\n   oHttp.setRequestHeader \"Content-type\", \"application\/json\"\r\n   oHttp.Send strJson\r\n\r\n  sHTML = oHttp.ResponseText\r\n  MsgBox sHTML\t\r\n  end function\r\n\r\nSub Vazia()\r\nEnd Sub<\/pre>\n
2.<\/strong> After the request for sending the message, the following response is displayed:<\/p>\n
\"\"<\/a><\/p>\n
<\/h2>\n
Using WhatsApp with Elipse E3\/Power via driver VBScript<\/strong><\/h2>\n
1.<\/strong> For performance reasons, we can implement text sending via the JSON-structured VBScript driver just by adding the lines below:<\/p>\n
\"\"<\/a><\/p>\n
DIM strMessage, strNumber, sHTML \r\n\r\nSub OnWrite_Number(r, v)\r\nstrNumber = v.Value\r\nEnd Sub\r\n\r\nSub OnRead_Number(r, v)\r\n v.Value = strNumber \r\nEnd Sub\r\n\r\nSub OnWrite_Message(r, v)\r\nstrMessage  = v.Value\r\nEnd Sub\r\n\r\nSub OnRead_Message(r, v)\r\n v.Value = strMessage  \r\nEnd Sub\r\n\r\nSub OnRead_Response(r, v)\r\nv.Value = sHTML \r\nEnd Sub\r\n\r\nSub OnWrite_Send(r, v)\r\n API_URL = \"https:\/\/api.chat-api.com\/instanceXXXXX\/sendMessage?token=1cwm5fzehdrmvowc\"\r\n strJson = \"{\"\"phone\"\": \"\"\" & strNumber & \"\"\", \"\"body\"\": \"\"\" & strMessage & \"\"\"}\"\r\n    \r\n   Set oHttp = CreateObject(\"Msxml2.ServerXMLHTTP\")\r\n   oHttp.Open \"POST\", API_URL, False\r\n   oHttp.setRequestHeader \"Content-type\", \"application\/json\"\r\n   oHttp.Send strJson\r\n\r\n  sHTML = oHttp.ResponseText\r\nEnd Sub\r\n\r\n<\/pre>\n
2.<\/strong> After that, create four tags in the driver and set them up via Item column (ParamItem <\/em>property), as seen below:<\/p>\n
\"\"<\/a><\/p>\n
 <\/p>\n
Finally, you will find a demo application attached to this article. This application was developed with v5.0.437, <\/strong>and it will demonstrate how to send WhatsApp messages via Elipse E3\/Power.<\/p>\n
