Enhance & Migrate WhatsApp API Software

WhatsApp API Software – Upgrade & Server Migration Project
Project Requirement
We have an existing WhatsApp API software platform and need an experienced developer/team to fix technical issues, improve performance, add new modules, and migrate the complete software to a new server without losing any existing data.

1. Existing Software Fixes
• Audit source code and database.
• Fix WhatsApp delivery-report issues.
• Correct Submitted / Sent / Delivered / Read / Failed status.
• Fix webhook and Message ID/WAMID tracking.
• Correct customer credit usage and billing.
• Fix existing loading/performance issues.
• Ensure software reports match WhatsApp/Meta data.

2. New Server Migration
• Configure new server.
• Migrate application, database and media.
• Configure domain, SSL, API, webhooks, queues and cron jobs.
• Test login, campaigns, WhatsApp sending and reports.
• Keep old server active until migration is fully verified.
• Complete final backup and data verification.
