🚀 Additional Context (Performance & Security)

Universal Auth: This endpoint is universal. It accepts credentials via Headers (Authorization: Bearer), JSON Body, or Query parameters.
Anti-Spam Shield (60s): Strictly enforced 60-second cooldown per recipient to prevent automated abuse and protect your sender reputation.
Subscription Aware: Systems automatically detect your plan. Unlimited users bypass local rate-limiting queues for immediate dispatch.
Validations: Automatically formats and validates phone numbers before dispatching to ensure high success rates.

Anti-Ban & Deliverability Engine 🛡️

We utilize advanced heuristics to protect your WhatsApp numbers from being flagged:

Template Rotation: Every request picks a random phrasing among 5 variations.
Mathematical Uniqueness: Every message includes a unique invisible/visible transaction ID to prevent hash-matching by WhatsApp.
Smart Delays: Messages are queued with random millisecond delays (3-8 seconds) to mimic human typing patterns.
