OTP means OTP
Keep the public API and customer experience centred on user-requested authentication, not unrelated message categories.
About MeraOTP
Authentication messaging with a narrower, safer focus.
MeraOTP helps Indian developers and businesses add transactional one-time-password delivery without turning a critical security flow into a general-purpose messaging tool.
Why we exist
OTP infrastructure should be understandable.
Authentication messaging sits at an important boundary: it has to be quick for a real user, difficult for an attacker to abuse, clear for an operator to process, and accountable for the business sending it.
MeraOTP is designed around that boundary. The product focuses on a single authentication OTP workflow, verified account context, approved integration sources, useful delivery records, and billing that a small team can understand.
That focus also means being direct about limits. MeraOTP is not a promotional bulk-SMS platform, does not replace a Customer's security programme, and does not erase applicable TRAI, DLT, consent, privacy, or telecom-provider obligations.
The principles behind the product
Commercial software earns trust through its defaults.
Know the source
Bind traffic to customer-managed server IPs and project domains. Localhost works automatically, and newly added hosted sources are enforced immediately.
Show the record
Give customers useful status, usage, plan, and transaction context without forcing them to reconstruct an event from scattered tools.
Collect with purpose
Request information needed for service, safety, billing, support, and compliance—and explain how it is handled.
Make abuse costly
Review suspicious use, enforce a clear Acceptable Use Policy, and preserve appropriate evidence for complaints and investigations.
No false guarantees
Communicate that delivery depends on networks, providers, approvals, device state, and good integration—not just an API response.
What the platform brings together
Built for the whole OTP operating loop.
Onboarding and verification
Account, contact, business, domain, and source context before production use.
Developer integration
A focused JSON endpoint, API-key controls, server-side guidance, and actionable responses.
Operations
Delivery records, credit balance, transaction history, plan validity, and support access.
Commercial access
Prepaid OTP credit with transparent rate tiers, plus a separate optional Payment Tools product.
Responsible use
OTP-only product rules, sender/template guidance, server IP allowlisting, and abuse review.
Trust also means saying what remains your responsibility.
MeraOTP generates, protects, expires, and verifies the OTP. Customers remain responsible for application and session security, the recipient relationship, lawful basis, privacy notice, acting on the verification result safely, and every PE, sender-header, content-template, consent, chain, and telecom-provider requirement that applies to their use.
