# Creating a Sandbox account The sandbox is a fully functional replica of the Txn platform for integration testing. It uses separate API credentials and test funds — no real transactions are processed. To request a sandbox account, contact your Txn sales or integration manager, or write to . Once your account is active, Txn will provision test balances so you can begin testing immediately. If you need additional test funds or cryptocurrency testnet liquidity, contact your integration manager. The sandbox base URL is `https://api.sandbox.txn.io`. Note that sandbox network codes differ from their production counterparts — testnet networks are prefixed (`tbtc`, `ttrx:usdt`, `hteth`, etc.). See [Supported currencies](/api-basics/supported-currencies.md) for the full list. Once your account is ready, [create your API keys](/getting-setup/creating-your-api-keys.md) to start making requests. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
