> Project tokens allow you to create permission-based API keys to use with the Hop API or SDKs

## Creating Project Tokens

You can create project tokens through the Hop console. Navigate to "Project
Settings" on the left Sidebar, then "Project Tokens".

</Frame>

Next, click on "Create Project Token". You will be presented with a modal:

</Frame>

You can grant permissions to the token so it can only access certain aspects of
your project, for extra security.

Once you've selected the necessary permissions, click **Create Token**. It will
appear in your list of project tokens.

</Frame>

You can now use the clipboard button to copy this token, and you're off to the
races!

## Using Project Tokens

You can use project tokens with our REST API and our server-side SDKs.

### SDKs

<CodeGroup>
  ```ts TS theme={null}
  import {Hop} from '@onehop/js';

  const projectToken = 'ptk_xxx';
  const hop = new Hop(projectToken);

  ```

  ```go Golang theme={null}
  import (
  	"context"
  	"fmt"

  	hop "go.hop.io/sdk"

  	// types is a package that contains all of the types used by the Hop API
  	// and other utility helper functions
   	t   "go.hop.io/sdk/types"
  )

  const HopToken = "ptk_xxx"

  func main() {
  	c, err := hop.NewClient(HopToken)
  	if err != nil {
  		// Handle your error here!
  		panic(err)
  	}
  }
  ```
</CodeGroup>

### API

When making requests to `https://api.hop.io`, specify the project token under a
HTTP header named `authorization`. That's all!
