Architectural & Delivery Breakdown
The Challenge
Reaching thousands of rural farmers and grassroots stakeholders via standard email or SMS suffered from low open rates (under 15%) and high recurring telecom costs.
Architectural Solution
Built an automated communication gateway using WhatsApp Cloud API:
- Engineered webhook endpoints in PHP to handle incoming delivery status updates and user responses.
- Implemented template-based broadcast messaging adhering to Meta compliance guidelines.
- Connected the pipeline to program database records to personalize messages and track engagement metrics.
Strategic Impact
Achieved an 88% message open and engagement rate within 30 minutes of broadcast, reducing communication costs by over 70% compared to traditional SMS gateways.
