WhatsApp Broadcast Message System Development

PROJECT: Simple WhatsApp Broadcast Sender Using WhatsApp Cloud API

We need a developer to set up a very simple system to send WhatsApp messages using the WhatsApp Cloud API.

Scope of work:

• Connect our WhatsApp number to the WhatsApp Cloud API via Meta Developers.
• Configure the API credentials and required setup.
• Create a simple tool/script that allows us to send WhatsApp messages to multiple phone numbers.
• The system should allow uploading a CSV file containing phone numbers.
• The system should send an approved WhatsApp message template to the numbers in the list.
• Provide basic logging showing which messages were sent successfully and which failed.

Requirements:

• Experience working with WhatsApp Cloud API
• Knowledge of API integration (Node.js / Python / PHP acceptable)
• Ability to deploy on a VPS server.

Environment:

We will provide a small VPS server where this system will be installed.

Deliverables:

• Fully working WhatsApp message sending system
• API setup completed
• Basic instructions on how to upload contacts and send broadcasts.

This is intended to be a lightweight internal tool, not a full CRM or chatbot platform.
