# Pagos API Authentication

You integrate with all Pagos services via RESTful APIs, secured and authenticated by a unified API key. This guide outlines how to request your API key and authenticate against the APIs:

* [Generate an API key](#generate-an-api-key)
* [Authenticate with the APIs](#authentication)

## Generate an API Key

To generate an API key:

<Steps>
  <Step>
    Click your **settings** icon in the top-right corner of your Pagos Service Panel.
  </Step>

  <Step>
    Under **Developers**, click **API Keys**.
  </Step>

  <Step>
    In the **API Keys** tab, click **Create API Key** to add a new key to your account.
  </Step>

  <Step>
    In the side panel that opens, set your **Key Name**, then click **Create API Key**.
  </Step>

  <Step>
    Copy your new API Key and store it somewhere secure.

    <Warning>
      This is the only time you can view this key!
    </Warning>
  </Step>

  <Step>
    Click **I've Copied My Keys** to confirm and exit the side panel.
  </Step>
</Steps>

You'll provide this API key with all API requests. Pagos uses this value alone to authenticate requests to our servers; you don't need to provide a password.

## Authentication

The Pagos platform uses API keys to authenticate requests to all our services. To access the API, you must authenticate via Bearer Authentication (e.g. for a cross-origin request). When you make any API request, pass an `Authorization` header in the following format:

```bash theme={null}
"Authorization: Bearer <api key>”
```

<Warning>
  All API requests must be made over HTTPS; calls made over plain HTTP will fail. API requests without authentication will also fail.
