Buying cryptocurrency on platforms like OKX can be fast and convenient, but mistakes happen. One common issue users face is making a payment error during a peer-to-peer (P2P) transaction—such as overpaying, underpaying, or sending funds to the wrong account. While these situations can feel stressful, there are clear steps you can take to resolve them quickly and securely.
In this guide, we’ll walk through what to do if you make a payment mistake on OKX, including how to handle overpayments, underpayments, and incorrect transfers. We’ll also cover how to use the platform’s built-in tools like IM chat,申诉 (appeal), and customer support to protect your assets.
Overpaying for a Cryptocurrency Order
It’s not uncommon for users to accidentally send more money than required when purchasing crypto. Whether due to a typo or misreading the amount, overpayment can happen—but the good news is that recovery options exist depending on the status of your order.
1. If the Order Is Still Pending
When you’ve completed the bank transfer and clicked "I have transferred the money", but the seller hasn’t released the cryptocurrency yet, the order remains in a pending state.
- Use the in-app messaging (IM) system to contact the seller directly.
- Politely explain the overpayment and request a refund of the excess amount.
- If the seller agrees, they can return the extra funds via their original payment method.

However, if the seller refuses to cooperate or doesn’t respond:
- Click the "Appeal" button at the bottom of the order page.
- Provide a clear description of the issue.
- Upload a screenshot of your transaction record showing the actual amount sent.
- A customer service representative will review your case and intervene as needed.
2. If the Order Has Already Been Completed
Once the seller has released the crypto and the transaction is marked as complete, you no longer have direct control over the process—but all hope isn’t lost.
- Immediately file an appeal using the same "Appeal" option.
- Alternatively, go to the Smart Customer Service section and select "Problem Feedback".
- Choose "Fiat Trading Issues" as the category.
- Describe your situation clearly and attach proof of payment.
- The support team will investigate and respond directly within the feedback interface.
Timely action increases your chances of resolution, so don’t delay reporting.
Underpaying During a P2P Transaction
Sending less than the agreed-upon amount is another frequent error, especially when dealing with time-sensitive transactions.
If you realize you've underpaid after clicking "I have transferred the money":
Option 1: Contact the Seller to Complete the Payment
- Reach out via the IM chat function.
- Ask if they’re willing to accept the remaining balance so the trade can proceed.
- If they agree, transfer the difference using their platform-verified payment method (e.g., bank transfer, Alipay, WeChat Pay).
- Once they confirm receipt, they can release the cryptocurrency.
Option 2: Cancel and Reorder
If the seller declines to accept partial payments:
- Request a full refund.
- Wait until you confirm the returned funds have arrived in your account.
- Then cancel the original order and place a new one with the correct amount.
⚠️ Important: If you can't reach the seller within 5 minutes, initiate an appeal immediately. Delays may complicate resolution.

Sending Funds to the Wrong Account
Payment method confusion or user error can lead to sending money to an unintended recipient. This scenario falls into two main categories:
Case 1: Used a Different Payment Method Than Specified
For example, you selected Alipay during checkout but accidentally paid via WeChat Pay, even though it belongs to the same seller.
What to do:
- Contact the seller via IM.
- Confirm whether they’ve received the payment through the alternate channel.
- If confirmed, ask them to release the coins as normal.
If they deny receiving it or refuse to cooperate:
File an appeal with screenshots proving:
- The seller's listed WeChat Pay details
- Your actual payment record
- Support staff will verify both parties’ claims and assist accordingly.
Case 2: Paid a Third Party by Mistake
This occurs when you send money to someone who isn’t involved in the trade—perhaps due to selecting an old recipient from your payment app history.
Immediate actions:
- Try contacting the recipient directly (if possible) to request a refund.
- Cancel the P2P order immediately through the app.
- Report the incident via problem feedback for documentation purposes.
- Consider involving your financial institution if the amount is significant.
Prevention tip: Always double-check payment details before confirming any transfer.

- Act fast: The sooner you report an issue, the better.

- Use official channels: Only communicate and transact within OKX’s secure environment.
- Don’t ignore virtual numbers: The phone number shown during trades is temporary (valid for only 3 minutes). If needed, refresh it from the app.
