Send WhatsApp using an Infobip MCP server and an AI client

This tutorial will teach you how to prompt an AI client to send a WhatsApp message. In this example, we use Claude Desktop but you can use any AI client that supports MCP integrations.

Prerequisites

Infobip account (opens in a new tab). If you do not have one, create a free trial account (opens in a new tab).
Infobip API key with the whatsapp:message:send scope. Find out more about API keys and scopes.
An AI client (e.g., Claude Desktop) with the Infobip WhatsApp MCP server. For integration details, see the MCP integration guide.
Sender. If in a free trial, use the Infobip test sender 447860099299 and activate it (opens in a new tab). If you want to configure a custom sender, request a new number or an alphanumeric sender through the Infobip account (opens in a new tab) or use the Infobip Numbers API (opens in a new tab).
Destination - a phone number to which the message will be sent. If in a free trial, you can only send messages to a verified phone number.

Integrate the Infobip WhatsApp MCP server with your AI client

Navigate to your AI client's MCP settings and add the Infobip WhatsApp MCP server.

json

{
  "mcpServers": {
    "ib-whatsapp": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.infobip.com/whatsapp",
        "--header",
        "Authorization: App ${INFOBIP_API_KEY}"
      ],
      "env": {
        "INFOBIP_API_KEY": "<Your Infobip API Key here>"
      }
    }
  }
}

Restart your AI client and you should see the Infobip WhatsApp MCP server on the list of available tools. For more integration details, see the MCP integration guide.

Send a WhatsApp message

In your AI client, write a prompt to send a WhatsApp message.

Key points about the prompt:

Specify the sender and destination(s).
Specify additional features you wish to include. Ask AI to show you available features or call the MCP server directly.

cURL

curl -X POST "https://mcp.infobip.com/whatsapp" \
  -H 'Authorization: App e08545ef7f5ffa50a4470da8388776e1-1391ec96-f7c1-43f9-8304-96880ab047d4' \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/list",
    "id": 1
  }'

Describe your use case so that the AI can craft an adequate message.
Include limitations (e.g., one message, specific delivery window) and personalized details (e.g., specific URL, image, etc.); otherwise, the AI will use made-up details to fill in the gaps.

AI prompt example

Create a WhatsApp message that advertises Shift Conference ticket options.
* Use this site for reference: https://shift.infobip.com/.
* Use this sender number 447860088970.
* Send to this number 447415774332.
* Include a brief conference description and a link to the conference website.
* use this image: https://shift.infobip.com/Infobip-Shift.jpg

The AI will choose an endpoint and create a request based on your specifications. Review and change it if need be. Once approved, the AI will send the message.

In this example, since the prompt specified an image, the AI chose an endpoint that allows for sending images over WhatsApp.
