OTP / TAC Messaging via WhatsApp Business API (WABA)
for Malaysia, Singapore and Indonesia

Official, Compliant OTP / TAC — Sent From Your Own Verified WhatsApp Business Account Sample of compliant OTP/TAC over WhatsApp Business API

WhatsApp no longer permits generic, shared or unofficial senders for business messaging. Every OTP / TAC must now be delivered through a WhatsApp Business Account (WABA) registered under your own Meta (Facebook) Business Account, from your own verified business number, using Meta-approved authentication templates. We handle the entire setup for you — Meta Business Account, business verification, number registration and template approval — typically within 1–3 business days.

Important Update — Generic WhatsApp Senders Are No Longer Available

Meta has tightened WhatsApp business messaging requirements. Shared sender pools and unofficial gateways are no longer permitted for OTP / TAC. To send on WhatsApp today, three things must belong to your company:

1. Your Meta Business Account

A Meta (Facebook) Business Account under your company name, with business verification completed. Mandatory for every sender — no exceptions.

2. Your Own WhatsApp Number

A dedicated number registered to your business — brand new, or ported from the WhatsApp Business App. Your customers see your brand, not a shared number.

3. Your Approved Templates

OTP / TAC content must be submitted as an Authentication template and approved by Meta before the first message is sent.

Good news: our team guides you through all three at no extra charge — most clients go live in 1–3 business days.

Why Choose Our WABA OTP / TAC Service?

WhatsApp Platform Rules & Eligibility

WABA runs on the official WhatsApp platform, and its rules apply equally to every business and every provider.

Rules That Apply to Everyone

  • Opt-in consent required — message only customers who agreed to hear from you.
  • Templates are pre-approved — Meta reviews every template and may pause or reject one at any time.
  • Quality rating is enforced — user blocks and reports reduce your messaging limits.
  • 24-hour window — free-form replies are allowed only within 24 hours of the customer’s last message.
  • Policies can change without notice — Meta updates rules and pricing at its sole discretion.

Restricted — Not All Businesses Qualify

  • Gambling and real-money gaming
  • Alcohol, tobacco and drugs
  • Medical and healthcare products
  • Firearms and hazardous goods
  • Crypto, ICOs and currency exchange
  • Adult products and dating services
  • MLM, payday loans and debt collection
  • Political parties, candidates and campaigns

Beyond our control: WABA account approval, template approval, quality enforcement, pricing and policy changes rest solely with the WhatsApp platform. We pass platform pricing changes through with appropriate notice, per the Mobiweb User Agreement.
