🚀 Additional Context (Performance & Customization)

Universal Auth: Accepts credentials via Headers (Authorization: Bearer), JSON Body, or Query parameters.
Custom Message Templates: Pass a custom 'message' parameter using placeholders {{otp}} (for the 6-digit code) and {{site_link}} (for your site URL).
Toggleable Unique ID: Control whether to append ID: XXXX at the end of the message via 'include_id' (true or false).
Configurable Cooldown: Set a custom resend delay via 'cooldown' parameter in seconds (Range: 10 to 600s, Default: 30s).
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.

Anti-Ban & Deliverability Engine 🛡️

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

Template Rotation & Custom Text: Supports template rotation or exact custom template formatting.
Mathematical Uniqueness: Option to append unique transaction IDs (ID: XXXX) to prevent hash-matching by WhatsApp.
Smart Delays: Messages are queued with random millisecond delays (3-8 seconds) to mimic human typing patterns.
