Multi-Company WhatsApp API Integration

I’m upgrading our Laravel-based CRM so every client company can plug in its own WhatsApp Business number through Meta’s official Cloud API, not a reseller platform. The job starts with setting up Meta Embedded Signup inside our app, continues through webhook handling and message-template management, and ends with production-ready token storage that survives refreshes and keeps each tenant isolated.

You’ll be working on:
• Meta Embedded Signup flow embedded in our existing onboarding wizard
• Webhook endpoints that route messages and events to the correct tenant context
• Template creation, approval syncing, and marketing-style broadcast support inside the CRM UI
• Secure, encrypted token lifecycle management for multiple numbers across companies

Acceptance is simple: a new tenant should be able to sign up, connect its number, send and receive templated or session messages, and view logs—all without touching the codebase.

If you’ve shipped something similar, send over a link or demo, your estimated timeline, and a quote broken into milestones. I’m ready to start as soon as I see a proven track record with Meta’s Cloud API in a multi-tenant setting.
