Send pdf invoice to my client through whatsapp

Job ID: 37584705

Budget: ₹1,500 – ₹12,500 INR

I'm seeking an experienced developer to integrate WhatsApp with my ERP software. The goal is to send PDF invoices to my clients via WhatsApp, a functionality that currently isn't available. I'm already using the ERP to send them confirmation messages on WhatsApp. The software is developed with PHP & JSON.

Requirements:
- Expertise in WhatsApp integration
- Strong skills in PHP & JSON
- Familiarity with ERP systems

Please note that there's a sense of urgency to this project, and I need it to be completed as soon as possible. The ERP software in use is currently undisclosed, thus flexibility and adaptability are key.
