The Basics (Overview)

This document will help you to get started with the basics such as authorization, sending and receiving messages.

Base URL https://waba-v2.360dialog.io

If you want to send a message using the /v1/messages endpoint, you must append the endpoint to your base URL then make the POST request.

Below is an example of a full POST request to the resource:

https://waba-v2.360dialog.io/messages

Authorization

Currently, there is only 1 method of authorization available, which is the API Key.

Retrieve your API Key

Refer to our documentation for API KEY generation.

When making POST requests, JSON data specified must be sent as POST data payload.

Each request to the needs to be authorized by adding D360-API-KEY in the header with your unique API Key as a value will grant access.

Example for POST request with curl:

curl \
    -H "D360-API-KEY: {{your-api-key}}" \
    -X POST \
    https://{{base-url}}/v1/messages \
    -H "Accept: application/json"
    ...

Example using Postman

Sending Messages

You can send messages by making a POST call to the /messages node regardless of message type. The content of the JSON message body differs for each type of message (text, image, etc.).

The request is as follows:

{ 
   "messaging_product": "whatsapp", 
   "recipient_type": "individual", 
   "to": "PHONE_NUMBER", 
   "type": "text", 
    "text":  {
        "body": "Hello, dear customer!"
    }
}

Receiving Messages

You must configure a callback (webhook URL) to receive messages.

Webhooks are used for:

• Inbound message notifications: Use it to get a notification you when you have received a message + message content

• Message status notifications: Monitor the status of sent messages.

If a webhook event isn't delivered for any reason (e.g., the client is offline) or if the webhook request returns a HTTP status code other than 200, we will retry the webhook delivery. We continue retrying delivery with increasing delays up to a certain timeout (typically 24 hours, though this may vary), or until the delivery succeeds.

Webhook Requirements

To deploy a live webhook that can receive webhook events from the WhatsApp Business API, your code must have the following:

• HTTPS support

• A valid SSL certificate

Your webhook must respond with status 200 for all incoming requests. It must also respond to requests in less than 80 milliseconds to prevent errors or delayed messages.

Webhooks (Incoming messages)

In the Cloud API it's possible to set WABA level webhook or phone number level webhook.

Webhook URLs for Cloud API do not support "_"(underscore) or ":xxxx"(port)in (sub)domain names. Invalid webhook URL: https://your_webhook.example.com Valid webhook URL: https://yourwebhook.example.com Invalid webhook URL:https://subdomain.your_webhook.example.com:3000 Valid webhook URL: https://subdomain.yourwebhook.example.com

Callback URL Header Authentication (Optional)

If the callback URL needs to be authorized by user, USER and PASS should be provided in the header Authorization that contains Basic base64(USER:PASS).

Request body example for USER=testuser and PASS=testpass

{
  "url": "{{your-callback-url}}",
  "headers": {
    "Authorization": "Basic {{token}}"
  }
}

Now, when a message is sent or received, you will receive a message notification to your webhook URL 😀
