# Setting Up Your Collection To get started, you need to set up a developer account and your first app by following the [Developer Dashboard Guide](/developer-guide/developer-dashboard-legacy.md). Once you have your app, navigate to "NFT Checkout" in the developer dashboard, and click "Create Collection": ![](/files/ZXTUkbF2jDp0CrMfhFK2) Enter: * A name + description (this will be displayed to your customers) * The contract address, type, and network from the previous step * A redirect URL for users to be sent to after purchase * An image to display in the checkout page for your customers If you deployed your contract to a testnet first (Goerli, Mumbai) make sure to select that network in the dropdown. **Testnet contracts can be tested in the NFT Checkout with "dummy" credit card data, whereas Mainnet contracts will always charge actual Fiat for minting.** That's it! Your NFT collection is ready to test: ![](/files/cfXrJ1lt72MZQYrxQoUa) If the user is connected with a different wallet to your service, you can specify `user_wallet_address` in the query params to specify the default wallet address you want to send the NFT. If no `user_wallet_address` is specified, the destination address will default to the Ramper wallet associated with the user's email login. --- # 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.
