Validate Email OTP API
Validate an email one-time password and confirm the customer controls the address they supplied, completing email ownership verification.
What the Validate Email OTP API does
Validate Email OTP checks the code entered against the one sent and confirms whether email verification succeeded.
A successful validation is the record that the address is genuinely reachable and controlled by the customer, which is what makes it usable for statements, notices and account recovery.
Where teams use the Validate Email OTP API

Frequently Asked Questions (FAQs)
What if the code is wrong?
Validation fails and the customer can retry until the code expires, after which you should send a new one.
How long should verification last?
Treat it as valid until the address changes. Re-verify on any change.
Is email verification enough on its own?
It confirms a communication channel, not identity. Pair it with document and mobile verification for KYC.
