# Crossmint keys create

> Create a new API key

The keys create command allows you to create a new API key for your Crossmint project.

To use it, run the following command from your terminal

```bash theme={null}
crossmint keys create
```

<Note>
  **Server-side keys** are view-once in Production, make sure to copy your API key secret when it’s displayed, as it
  won’t be shown again.
</Note>

<Note>
  **Client-side keys** require selecting the app type and adding allowed origins—use domain URLs for web or
  package/bundle IDs for mobile.
</Note>

## Example

Start the API key creation process:

```bash theme={null}
crossmint keys create
```

Select the type of key you want to create:

```
? Select Key Usage: (Use arrow keys)
  Server side
> Client side
```

For client-side keys, select the application type:

```
? Select client platform: (Use arrow keys)
> Web
  Mobile
```

Specify the allowed origins for your key.

* For web enter the domain, eg: [https://crossmint.com](https://crossmint.com)
* For mobile enter your Android Package name or IOS Bundle ID, eg: com.company.appname

<Tip>Enter multiple domains or app identifiers separated by a comma.</Tip>

```
? Enter whitelisted domain or localhost (e.g., https://www.yourdomain.com) (separate multiple domains with a comma):
https://www.crossmint.com
```

Select the scopes you want to add to the key by pressing space. Once you are ready, press enter to create the key:

```
? Select scopes for client key:
● Read wallet (wallets.read)
● Create wallet (wallets.create)
○ Create Transaction (wallets.transactions.create)
○ Sign Transaction (wallets.transactions.sign)
○ Read Transactions (wallets.transactions.read)
○ Create Wallet Signatures (wallets.signatures.create)
```

The CLI will display the created API key information, this includes the Key ID and Client Secret:
