# How to integrate B2BINPAY
[B2BINPAY](https://b2binpay.com/) can be connected to B2CORE through [PSS](/integrations/payment-systems.md#payment-system-service-pss), with support for deposits with [static payment details](#deposits-with-static-payment-details-via-b2binpay) and withdrawals.
{% hint style="warning" %}
The **Travel Rule** isn't currently supported for this integration because the corresponding driver for connecting to B2BIТPAY doesn't yet support **Travel Rule** requirements.
{% endhint %}
Follow the instructions below to configure the B2BINPAY connections and set up the deposit and withdrawal methods in the B2CORE Back Office. These instructions correspond to the [General procedure](/how-to-articles/manage-payment-methods/how-to-add-deposit-and-withdrawal-methods-through-pss.md) for adding methods for PSS-supported payment systems, but include details specific to B2BINPAY.
{% hint style="info" %}
Before proceeding with the instructions, you must have signed up for B2BINPAY and have an active wallet.
{% endhint %}
## Supported currencies
For the list of supported currencies for deposits and withdrawals via B2BINPAY, refer to [Currency codes](https://docs.b2binpay.com/references/currency-codes) in the B2BINPAY documentation.
## Configure connections to B2BINPAY
If you plan to use B2BINPAY for both deposits and withdrawals, you must configure two separate connections: one for deposits and another for withdrawals.
To configure a connection to B2BINPAY:
{% stepper %}
{% step %}
In the B2CORE Back Office, navigate to **System** > **External connections**.
{% endstep %}
{% step %}
Click **+Create** in the upper-right page corner.
{% endstep %}
{% step %}
On the **Create connection** page, fill in the following fields:
* In the **Name** field, enter a name for the connection. The name must be unique and may only contain Latin letters, numbers, dashes, and underscores (for example, `Deposits_B2BINPAY` or `Withdrawals_B2BINPAY`).
* In the **Caption** field, enter a caption that will be applied to the connection in the Back Office.
* In the **Provider** dropdown, select:
* **PaymentSystemStaticDeposit** — to add a connection that will be used for a deposit method that supports **static payment details**.
* **PaymentSystemWithdrawal** — to add a connection that will be used for a withdrawal method.
{% endstep %}
{% step %}
In the **Driver** dropdown that appears, select **B2BINPAY V3**.
{% endstep %}
{% step %}
In the **Credentials** section that appears, configure the B2BINPAY-specific settings:
* In **API base URL** field, specify the base URL provided by B2BINPAY for your integration environment.
* In the **Client ID** field, enter your client identifier provided by B2BINPAY.
* In the **Client secret** field, enter the secret key associated with your client ID.
* In the **Callback secret** field, enter the key used to verify callback notifications from B2BINPAY.
For more details, refer to [How to access the API](https://docs.b2binpay.com/how-tos/manage-your-profile-and-system/how-to-access-api) in the B2BINPAY documentation.
{% endstep %}
{% step %}
Click **Save** to create the connection.
The B2BINPAY connection will appear in the list of external connections.
{% endstep %}
{% step %}
Check the connection status.
If the connection is inactive (**No** is displayed in the **Enabled** column), click the **Edit** button to open the connection details and set the **Enabled** dropdown to **Yes**.
{% endstep %}
{% step %}
Click **Save** to apply the changes.
{% endstep %}
{% endstepper %}
If you need to support both deposits and withdrawals via B2BINPAY, follow the same instruction to create a new connection for the other operation.

{% step %}
Click **Test configuration** to validate the connection settings of the withdrawal method.
The test result will be displayed on the page.
{% endstep %}
{% step %}
After successfully validating the configuration, click **Save**.
{% endstep %}
{% endstepper %}
The **B2BINPAY** withdrawal method is now configured in the B2CORE Back Office.
## Blockchain selection for Merchant and Enterprise wallets
In the **Configuration** section of a deposit or withdrawal method, you must select the wallet that will be used for processing transactions. The wallet type determines how the blockchain for processing transactions is defined.
* When using **Merchant** wallets, clients can select a blockchain for processing their transactions, depending on the chosen deposit or withdrawal currency.
For example, if the deposit currency is USDT, available blockchain options such as **Ethereum** (ETH), **Tron** (TRX), or **BNB Smart Chain** (BSC) may appear, depending on your **Merchant** wallet configuration in B2BINPAY.
* When using **Enterprise** wallets, the blockchain on which transactions are processed is predefined by the wallet currency.
For example, if your **Enterprise** wallet holds **USDT on Ethereum** (ETH), deposits will always be processed on the **Ethereum** (ETH) blockchain.
## Deposits with static payment details via B2BINPAY
Deposits with static payment details via B2BINPAY allow clients to generate one or more blockchain-specific deposit addresses in the B2CORE UI. These addresses are saved for future use and can be reused for subsequent deposits.
The example below shows how the payment form appears in the B2CORE UI for the B2BINPAY deposit method with **static payment details**. On the form, a client can generate payment details for making deposits in USDT on either the **Ethereum** (ETH) or **Tron** (TRX) blockchain. The generated address are saved and can be reused for future deposits. These addresses can be copied and used without the need to open the **Deposit** page in the B2CORE UI.
