Penny Drop Initialize API
Start an asynchronous penny-drop verification and receive a reference ID you can poll, built for bulk and queue-based account checks.
What the Penny Drop Initialize API does
Penny Drop Initialize begins a verification without waiting for the bank to respond. You submit the account number, IFSC, expected holder name and amount, and immediately receive a reference ID.
Splitting initiation from the result suits batch processing: you can queue thousands of accounts without holding open connections, then collect outcomes with Penny Drop Verify as they settle. Interbank transfers can take time, and this pattern stops that latency blocking your own workers.
Where teams use the Penny Drop Initialize API
Queueing overnight verification of a large beneficiary file
Verifying accounts from a background worker rather than a web request
Handling banks whose responses are too slow for a synchronous call
Building a retry-safe verification pipeline
Frequently Asked Questions (FAQs)
How long should I wait before checking the result?
Most verifications settle within seconds, but interbank timing varies. Poll with a short backoff rather than a fixed delay, and treat pending as a normal intermediate state.
How long is the reference ID valid?
Long enough to cover any realistic settlement window. Store it against your own record so a result is never orphaned.
Can I use the synchronous version instead?
Yes. Bank Verification Penny Drop performs the same check in a single call and suits interactive flows where the customer is waiting.
