To get started: 1. Create a developer account on the [Staging](https://staging.crossmint.com/console) or [Production](https://www.crossmint.com/console) consoles. Read more about the environments [here](/introduction/platform/staging-vs-production). 2. Create an [API key](/introduction/platform/api-keys) from the `API keys` tab on the console, with the permissions required for the APIs you want to use. 3. From the page of your API of choice, insert the right API key in the authorization slot, introduce the different parameters, and call "Send". 4. (Optional) To call APIs in the production environment, find the API endpoint selector (`⌄`) next to the endpoint URL, and change it to `www.crossmint.com/api`. The following guide will show you how to create a wallet and mint an NFT into it within 5 minutes. For this, make sure your API key has the scopes `wallets.create`, and `nfts.create`. Follow the next steps to create a wallet within 5 minutes: Navigate to create wallet endpoint screenshot with light theme Navigate to create wallet endpoint screenshot with dark theme Set environment URL screenshot Set environment URL screenshot Set x-api-key screenshot Set x-api-key screenshot You may add any additional properties. Each API reference page includes the full list of properties and admissible values.

In the previous guide, you created a wallet. Now you will deliver an NFT into it and read the wallet's content.

You can create new ones using the [Create Collections](/minting/nfts/integrate/create-collections) API.

Look closely at the screenshots below to see where it is. Select EVM metadata URL option screenshot with light theme Select EVM metadata URL option screenshot with dark theme
Enter metadata URL screenshot with light theme Enter metadata URL screenshot with dark theme You can provide your own or use this example URL: ```bash metadata URL theme={null} https://bafkreidbf4jpxpecwezjbagwmua5qv62ifhhtzsspoml7zls6iq6ms4byi.ipfs.nftstorage.link/ ``` ```json example JSON theme={null} { "name": "Crossmint Test NFT", "description": "Created with the Crossmint minting API", "image": "https://bafkreiexjl6kw4khdxkrt6dojgacscnzvrys47t472l2t7d6r2ss65kifq.ipfs.nftstorage.link/", "external_url": "https://docs.crossmint.com", "attributes": [ { "trait_type": "contract", "value": "ERC-721" }, { "trait_type": "background", "value": "black" } ] } ```
This URL must point to a valid JSON file that adheres to [EVM metadata standards](/minting/nfts/integrate/define-metadata). Enter metadata url screenshot with light theme Enter metadata url screenshot with dark theme There are two options for the `recipient` parameter. The first enables minting to an email address. The second enables minting directly to a wallet address. ```javascript email recipient theme={null} // format email:: // example email:testy@crossmint.xyz:polygon ``` ```javascript wallet recipient theme={null} // format :
// example polygon:0x0359Cd99FD20e853a85489DFC93EaDFeF7461590 ```
Enter your own email address on this step and you can login to see your NFT in the Crossmint wallet later, which can be accessed from [crossmint.com](https://crossmint.com) or [staging.crossmint.com](https://staging.crossmint.com) if you are in staging.

Crossmint has a 10MB re-upload size limit. For larger files, upload your media to IPFS, create a metadata.json as shown above, submit the metadata file's URL, and ensure `reuploadLinkedFiles` is set to `false`.

The default option is `true`.

If you minted directly to a wallet address you can view the NFT in that application. Ensure you are accessing it from a testnet if you used staging.
