Sandbox (Test API Key)

Introduction 
14-June-2021: we have updated our Sandbox number to 4930609859535 
We provide a developer-friendly test environment, for anyone that wants to check out the usage of our WhatsApp API. The WhatsApp API allows for direct-like access to the WhatsApp Business API. In the test environment, you can test sending messages and templates as described in the WhatsApp messages docs and receive a Webhook as described in the WhatsApp Webhook docs.
Sandbox Base Path: https://waba-sandbox.360dialog.io/
Because of security reasons, in the sandbox environment, each phone number has its own Test API-KEY, and you are able to test sending messages/templates only to your phone number.
Limitations
What you can do in the Sandbox 
1.You can use the Test API-KEY to send text messages and text templates to your own phone number. 
2.An unlimited amount of messages can be sent with the sandbox.
3.Your phone number acts like a user and can send and receive messages. 
4.The number can be a landline number, as long it is able to use WhatsApp.
5.You can switch the endpoint at any time. If you don't have one yet you can use a free service like RequestBin to set up an endpoint. 
6.Each Sandbox API Key is linked to one phone number and you can only send test messages to that phone number. If you wish to test messages with more than 1 number then it is advised to set up a test WhatsApp Business Account (Staging WABA) to use instead of the Sandbox.
What you can't do with the Sandbox
1.The Sandbox is a test environment only. You will not be able to use it to send messages to your clients. You can only send messages to your own phone number. 
2.Templates messages can be sent a maximum of 10 times. You can choose between 2 predefined templates. 
3.Messages and Templates can be sent only to your own phone number.
4.We will only forward and trigger an API when your given number is involved. 
5.We do not yet provide response information when you use the WhatsApp API.
6.You only have access to the WhatsApp API. 
7.Our Sandbox is available to test via the API, but any automated tests would have to be configured from your end. 
1. Get a Test API Key
To get a test API-KEY you can:

Send a WhatsApp message from your phone to the phone number 4930609859535  with the contentSTART
Use this link: https://wa.me/4930609859535?text=START​
Use this QR code: 
​
​
​
As a response, you will receive your TestAPI-KEY.This API-KEYis associated with your phone WhatsApp number. Now you are able to use the 360dialog WhatsApp API. You can set your own Webhook or send an unlimited number of messages and limited (10) templates.
2. Set your Sandbox Webhook URL

3. Send a Message to the Sandbox
Now, send another message (any message) from your device to the Sandbox number: 4930609859535.You will receive the Inbound Message Notification on your webhook 😀
4. Respond using the Sandbox API

Example Request Payload  
1
{
2
    "recipient_type": "individual",
3
    "to": "insert_your_number",
4
    "type": "text",
5
    "text": {
6
        "body": "Hello, dear customer!"
7
    }
8
}
Copied!
5. Send a Template Message (optional)
There are 3 templates available to test in the Sandbox. There is no possibility to add or edit a Sandbox templates, you must use the predefined templates.

Templates are: 
disclaimer 
Using this template will just send a regular text message, which can’t be edited.

first_welcome_messsage  
This is an example of a template with a personalization possibility (you can personalize the receiver's name). 

interactive_template_sandbox
This template contains 2 buttons for which you can pass customer URLs. 
You always have to use the predefined namespace which is c8ae5f90_307a_ca4c_b8f6_d1e2a2573574.

            "code": "de"
9
        },
10
        "name": "disclaimer"
11
    }
12
}
Copied!
Note that this example covers first_welcome_messsage with personalization. In the case of the disclaimer template, the payload is similar but without the componentsobject (it holds personalization parameters which are not used in disclaimer).
Get new Sandbox API Key
You may recreate / get a new Sandbox API Key at any time by re-sending a WhatsApp message with content START to number 4930609859535. When you create a new API Key for your WhatsApp Number any existing Sandbox Keys associated with your number will be revoked. 
Code Examples For Developers
Python
Creating an API key
Send a WhatsApp message START to the number 4930609859535. In the following examples, we assume your phone number is 49YOURNUMBER. Save the D360-API-KEY (in the examples it is described as YOUR_API_KEY).
Setting your Callback URL (optional)
Use an external service (such as requestbin.com) to test webhook responses, or create your own webhook server for tests. In the case you want to test with localhost, you may use an external service (such as ngrok).
