Resolve Crypto Wallet Webhook Duplication Issue
Budget: $250 – $750 USD
Fix bugs in crypto wallet using webhook When a webhook gives extra credits when a deposit is replaced, it could be due to a few potential issues:
1. Duplicate Event Handling
Problem: If your webhook system is not idempotent (i.e., it doesn't prevent the same event from being processed more than once), it might be treating a "replace" event as a new deposit, rather than an update to the existing one.
Solution: Implement idempotency in your webhook system, so the same event doesn't trigger multiple crediting actions. Each deposit or transaction should have a unique identifier, and your system should check if that identifier has already been processed.
2. Incorrect Event Mapping
Problem: The webhook may be configured to handle different deposit-related events in a similar way, so when a deposit is replaced, the webhook might interpret this as a new deposit.
Solution: Ensure that the "replace" event is treated differently from "new deposit" events. For example, a "replace" event should adjust or update the original deposit rather than adding new credits.
3. Business Logic Errors
Problem: The logic in your system may not be correctly distinguishing between an initial deposit and a replacement event, causing credits to be applied twice.
Solution: Review your business logic and ensure that a replaced deposit results in the adjustment of credits, not a new addition. You might need to implement checks to see if the original deposit is being replaced, and adjust the credit balance accordingly.
4. API Miscommunication
Problem: If your system relies on an external API for deposits and credits, there could be miscommunication between your system and the API when handling replaced deposits.
Solution: Check the API documentation to see how deposit replacement is handled and ensure your system correctly interprets those events.
5. Concurrency Issues
Problem: If multiple webhook events are processed simultaneously, race conditions can occur, where two instances of the same event result in extra credits being added.
Solution: Implement locking mechanisms or queuing to ensure that events are processed in the correct order and without duplication.
By diagnosing and addressing these potential issues, you can ensure that deposit replacements don’t incorrectly result in extra credits.
Also other bugs that can repeat in transaction log of failed withdrawal. Correct message when it's a successful withdrawal. Fix bug in crypto invoice. Add amounts to deposit received by customers
