OTP delivery failures
SMS OTPs get delayed or filtered. WhatsApp Authentication templates often deliver faster with higher read rates — when the customer has WhatsApp active.

Can WhatsApp API send OTP for banking?
WhatsApp Business API for finance supports OTP delivery, loan application updates, KYC reminders, and account notifications — with authentication templates and encrypted messaging via Meta's Cloud API. Not every use case qualifies for every template category; plan Meta review time.
Yes. Meta provides an Authentication template category for OTP and verification codes. Ominiflow supports programmatic OTP delivery via API. Fallback SMS is still wise for customers without WhatsApp.

Challenges We Solve
Loan application drop-offs
Applicants abandon mid-KYC. Automated nudges recover a share of incomplete applications; complex cases still need human underwriters.
Manual status updates
Call centre agents repeat "your application is under review" hundreds of times daily.
Document collection
Collecting KYC documents via email is slow. WhatsApp forms streamline upload — with secure handling per your policy.
Regulatory compliance
Financial messaging requires audit trails and consent management.
Payment reminders
EMI due dates need reliable, timely notification channels with clear opt-in.

Can WhatsApp API send OTP for banking?+
Yes. Meta provides an Authentication template category for OTP and verification codes. Ominiflow supports programmatic OTP delivery via API. Fallback SMS is still wise for customers without WhatsApp.
Is WhatsApp secure for financial messaging?+
WhatsApp Cloud API uses encryption in transit. Ominiflow adds role-based access, audit logs, and consent management. Your compliance team must approve which data appears in message body text vs secure links.
Can NBFCs collect KYC documents on WhatsApp?+
Yes. Use WhatsApp forms to collect Aadhaar, PAN, and income documents with secure upload and CRM sync. Document retention and verification rules remain your responsibility.
How do loan status updates work?+
Ominiflow triggers Utility templates at each application stage — submitted, under review, approved, disbursed — via CRM webhooks or API. Stages must map to approved template content; ad-hoc free text outside the 24-hour window is not allowed.
Does Ominiflow integrate with loan origination systems?+
Yes. Webhooks and REST API connect to custom LOS, Zoho, and enterprise banking systems. Integration scope and timeline depend on your LOS API maturity.
