POSTBank Account Verification

Verify a bank account by transferring ₹1 (penny drop) and retrieve the account holder name, account status, and branch details in real time.

POST/tools/kyc/bank-account/sync

Performs a live penny-drop transaction of ₹1 to the specified bank account and returns the account holder name as registered with the bank, account status, IFSC details, and the UTR of the debit. Use this before payouts to prevent failures and fraud. The ₹1 is credited to the beneficiary — no refund occurs. Supports all IMPS-enabled banks in India.
