# Missing deposits

## Problem

* The payer sent me funds, but I didn't receive the payment.
* I can't find the incoming transaction in the external systems.

## Possible reasons

These issues may occur due to:

* The transaction still being processed on the blockchain.
* Wrong deposit address.
* Missing callback details.

## Solution

Here are several ways that can help you verify the transaction.

{% step %}

#### Check for transfers

Go to the **Wallet management** > **Transfers** page and filter transfers by [TXID](https://docs.b2binpay.com/references/key-terms#txid). Double check the TXID was accurately obtained or provided.

* If the transfer is found and assigned the *Confirmed* status, it means that it has been successfully processed and credited to your wallet.
* If the transfer is found but assigned the *Unconfirmed* status, it means that the transaction hasn't yet received enough block confirmations on the blockchain, please wait. Once the required number of confirmation blocks received, the transfer status in B2BINPAY will change to *Confirmed*, and the deposit amount will be credited to your wallet.

{% hint style="info" %}
The confirmation time may vary based on the blockchain used, fees paid, and network load. Use [block explorers](https://docs.b2binpay.com/references/block-explorer-list) to check if the transaction has received enough confirmations on the blockchain. You can find the required number of block confirmations for different currencies [here](https://b2binpay.com/en/available-currencies).

If the transaction is confirmed on the blockchain, but in B2BINPAY the transfer remains unconfirmed for an extended period, there might be a technical issue. Contact the Support Team for further assistance: provide the TXID and transfer ID.
{% endhint %}
{% endstep %}

{% step %}

#### Check the deposit address

If no transfer is found, verify if the deposit address is associated with the system. Go to the **Wallet management** > **Deposits** page and filter deposits by the address.

* If the deposit is located but no transfers were credited, contact the Support Team for further assistance. Provide the TXID, address, and deposit ID.
* If no deposit is located, it indicates that the address is not within the system, and such deposits can't be credited.
  {% endstep %}

{% step %}

#### Check for callback issues

Even if the transfer is found and confirmed in B2BINPAY, it still can be missing in the external systems due to [callback](https://docs.b2binpay.com/references/key-terms#callback) issues.

1. Go to the **Wallet management** > **Deposits** page, find the required deposit and click its **ID** to access the details. In the **Advanced options** on the **Settings** tab, verify that the **Tracking ID** and **Callback URL** are correctly specified. Adjust them if needed. Missing these details can cause callback issues, leading to unrecorded transactions in the external system.
2. Ensure the server handling callbacks is correctly configured and functioning.
3. Go to the **Wallet management** > **Callbacks** page, locate the corresponding callback, and click the **Resend** button.

* **Unsupported blockchains**: Transactions can only be credited if the blockchain is supported by the system. Transactions on unsupported networks can't be recovered.
* **Unsupported tokens**: Funds can be reversed, contact the Support Team for further assistance.
