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.
