Frequently Asked Questions
Common developer queries about the Retry Mandate Installment API and automated recovery workflows.
What is the Retry Mandate Installment API?
The Retry Mandate Installment API is an automation endpoint designed to re-initiate failed recurring payment collections. It allows merchants to trigger a fresh debit attempt against an existing mandate after an initial installment failure.
2. When should I trigger a retry attempt?
You should trigger a retry when an installment fails due to soft declines such as 'Insufficient Funds' or temporary technical errors. It is best used within the grace period allowed by your service agreement and NPCI guidelines.
3. Is a new customer authorization required for retries?
No. The Retry API utilizes the original mandate authorization (E-Mandate/NACH). As long as the mandate remains 'Active' and the retry amount is within the authorized limit, no further customer intervention is needed.
4. How many times can I retry a failed installment?
While our API supports multiple attempts, NPCI and banking regulations typically limit the number of retry attempts per installment cycle. We recommend following a T+2 or T+5 retry schedule to maximize success.
5. What happens if a retry fails again?
If a retry fails, the API returns a detailed decline code. Depending on the reason (e.g., 'Account Closed'), you may choose to halt further retries and move the account to a manual collection or suspension workflow.
6. Can I retry a partial amount of the installment?
Yes, the API allows you to specify the amount for the retry attempt, provided it does not exceed the maximum authorized limit defined in the original mandate registration.
7. Are there additional charges for using the Retry API?
Retry attempts are treated as standard transaction requests. However, frequent failures might incur bank-level bounce charges for the customer. It is advisable to use retry logic judiciously.
8. How do I reconcile a successful retry?
Each retry request generates a unique 'retry_id' which is linked to the 'original_txn_id'. You can use our webhooks or reconciliation reports to match these IDs and update your billing records.
9. Does the API support bulk retry requests?
Yes, for large-scale recovery operations, the API can process batch retry instructions. This is ideal for managing thousands of subscription renewals or loan repayments simultaneously.
10. How soon after a failure can I initiate a retry?
Technically, a retry can be initiated as soon as you receive the failure notification. However, for fund-related failures, waiting 24-48 hours often yields higher success rates as it aligns with typical customer salary cycles.
