Frequently Asked Questions

Payment Handling & Reconciliation

How does LetKnow Pay handle underpayments and overpayments?

LetKnow Pay’s payment page provides a configurable underpayment threshold (0% by default), notifying clients immediately if their payment is insufficient and allowing 60 minutes to complete the full amount. For overpayments, the exact requested amount is sent via webhook, while excess funds are displayed in the merchant dashboard for manual credit or refund. Exchange rates are locked for 60 minutes, ensuring the webhook amount always matches the original payload, eliminating reconciliation issues.

Is the payment page compatible with subscription or fixed-price models?

Absolutely. LetKnow Pay ensures exact payments for subscriptions or fixed-price goods by locking exchange rates for 60 minutes and enforcing a 0% underpayment tolerance by default. This guarantees that payments are processed only when the exact amount is received, preventing CRM mismatches and manual errors.

What happens if a customer sends crypto via the wrong network?

LetKnow Pay intelligently handles common mistakes, such as sending USDC on the wrong network (e.g., ERC20 instead of BEP20). The platform treats tokens as unified currencies, automatically reconciling cross-network payments to reduce failed transactions and refund requests.

How are duplicate deposits managed?

Duplicate deposits are flagged in your merchant portal, and you can choose to refund or manually credit the funds. Webhooks are triggered only after your action, ensuring accurate financial tracking and clean CRM data. This feature prevents disruptions and maintains operational efficiency.

Cryptocurrency & Network Flexibility

Can I add new cryptocurrencies or networks without development work?

Yes. Merchants can instantly enable newly supported assets without additional development, and currency offerings can be customized per merchant for greater flexibility.

Does LetKnow Pay support unhosted wallet verification?

Yes, the platform supports unhosted wallet verification through digital signatures or wallet ownership screenshots. This feature helps meet compliance requirements while simplifying the onboarding process for traders.

Merchant Operations & Compliance

How does LetKnow Pay simplify setup and configuration?

The payment page eliminates complexity by requiring merchants to define only the fiat/CRM currency displayed to users. Settlement currencies are managed automatically by LetKnow Pay on a per-merchant basis, reducing onboarding time and minimizing configuration errors.

How does LetKnow Pay ensure compliance?

LetKnow Pay handles compliance entirely, enforcing geo-based currency restrictions (e.g., disabling USDC for EU users) and supporting unhosted wallet verification through digital signatures or screenshots. This removes the compliance burden from merchants, mitigating legal risks and enabling safe global operations.

How does LetKnow Pay help reduce support workload?

By automating underpayment resolution, cross-network reconciliation, and duplicate deposit handling, LetKnow Pay minimizes manual intervention. Traders receive real-time guidance, reducing the need for support tickets and streamlining operations for your team.
