OTPs that arrive in under 5 seconds.

Yes — Meta requires opt-in for business-initiated messages, and the cleanest pattern is a channel picker at signup or login where the user chooses WhatsApp. InfiQ stores consent records with timestamps so you can evidence opt-in later.

Authentication templates use Meta's fixed copy, so approval usually takes minutes rather than the days free-form templates can need. You pick the button type (copy code or one-tap autofill), expiry warning and security disclaimer, then submit through InfiQ's dashboard or API.

InfiQ fires a delivery webhook within seconds of each send, so your system knows immediately whether a code landed. Most teams trigger SMS fallback if no delivered status arrives within 10–15 seconds, which keeps login success higher than either channel achieves alone.

Not freely — Meta locks authentication template copy to keep the category fast and abuse-resistant. You can add an expiry warning and a security disclaimer, and the code placeholder is filled per message through the API.

In India and many emerging markets, Meta's authentication rates typically come in 30–40% below A2P SMS, though pricing varies by country. Run both routes side by side during the 7-day free trial and compare cost per delivered code from your own dashboard.

Messages are encrypted in transit, and you can set a code expiry window so stale OTPs can't be reused. InfiQ adds consent records, audit logs and access controls, with API keys scoped per application.
