# Checklist Before initiating live payments, our integration team needs to verify your integration to ensure all essential steps are completed accurately. This verification involves a 30-minute call where we'll explore the following areas: * [ ] **User Onboarding and KYC:** Describe your approach to onboarding new users and conducting Know Your Customer (KYC) checks. * [ ] How do you handle PAD pre-authorized-debits for EFT and ACH? * [ ] **Transaction Idempotency:** Explain your methods for preventing duplicate transaction processing to maintain data integrity. * [ ] **Transaction Failures:** Outline your strategy for managing transactional errors and ensuring error resilience. * How do you handle failures, specifically late failures for EFT and ACH? * [ ] **Webhooks Implementation:** * How do you manage webhook delivery failures? * What security measures have you implemented for webhooks, such as HMAC signatures or IP restrictions? * Have you configured email notifications to be alerted about failed webhook events? * [ ] **Wallet Balance Management:** * Have you set up email notifications to alert you when wallet balances become negative? * [ ] **Production Account Limits:** Confirm your awareness and understanding of the current limits on your production account. * [ ] **Zūm Rails API Usage:** Confirm which Zūm Rails APIs your system interacts with and the frequency of these calls. * [ ] **Status Page Subscription:** Confirm your subscription to our status page to stay informed about system updates and issues. This discussion will help ensure a robust and secure integration. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
