Base URL {{base\_url}} - Your server Address<br>

* Where the application is hosted

#### Master Key {{master\_key}} - Your secret key <a href="#master-key-master_key-your-secret-key" id="master-key-master_key-your-secret-key"></a>

***

**Step 1 - Generate API Key**

* Call to this enpoint is protected by an authorization header with the value of a master key
* API Key is equivalent to a WhatsApp Device
* **After generating an API please save it in a safe place as there is no list of API Keys generated**\
  **HTTP POST**

  ```
  http://{{base_url}}/api-keys/generate
  header: "Authorization": "{{master_key}}"
  body
  {
      	"whatsapp_device_no": "1"
  }
  ```

  **whatsapp\_device\_no** - this can be any number, it can represent user\_ids on your system. Each number is tied to an API Key<br>

  **Step 2 - Scan WhatsApp Device**

  * This requires an API Key and should be done from a browser
  * ***On successful connection, your API is ready to use***

  <http://{{base_url}}/connect-wa/scan-device?api_key=API-X-xxx>\
  \
  **Step 3 - Check if a number is on WhatsApp**

  * This requires an API Key in the query params

  **HTTP GET Request**

  ```
  http://{{
  base_url}}/connect-wa/scan-device?api_key=API-X-xxx
  ```

**Step 4 - Send WhatsApp Message** **HTTP POST Request**

* This requires an API Key in the body params

http\://{{base\_url}}/send-messages/send

```
{
	
	"api_key": "API-X-xxxx",
	"message": "Your OTP is *1234*",
	"to_phone": "111xxxxxxxx",
	"verify_check": true
