# Set up integrations

Coinsbuy is designed to integrate seamlessly into various external systems to streamline and automate payment processes, such as creating deposit addresses, fetching exchange rates, processing withdrawals, and so on.

To ensure a secure and comprehensive testing experience, Coinsbuy provides a Sandbox environment. This allows you to experiment with the platform features safely, understand the system logic, test interactions, set up integrations without any risk, and tailor them to your specific scenarios. You get access to Sandbox immediately after signing up to the system.

Coinsbuy provides you with the Testnet faucet: using it, you can receive test funds to your Sandbox wallet to test system functions — payouts, deposits, transfers, and other features. Currently, the **BTC** testnet faucet is supported.

To receive test funds:

{% stepper %}
{% step %}
Create a BTC wallet in the Sandbox environment.
{% endstep %}

{% step %}
Access the wallet details and copy the wallet address.
{% endstep %}

{% step %}
Click your **profile icon** in the upper right page corner and select **Testnet faucet**.
{% endstep %}

{% step %}
In the **Address** field, paste your wallet address.
{% endstep %}

{% step %}
In the **Amount** field, enter the amount to deposit. Amount limits are specified under the field.
{% endstep %}

{% step %}
Click **Send deposit**.
{% endstep %}

{% step %}
Simulate transaction confirmations by clicking the **Generate blocks** button several times.
{% endstep %}
{% endstepper %}

Now, as your wallet is topped up, you can proceed with testing the financial operations in Coinsbuy and configuring integrations with external systems.

{% hint style="danger" %}
Never use Sandbox deposit addresses on Production environments. This will result in **irreversible loss** of funds.
{% endhint %}
