# Obtaining a PEX API key

> Register for a PEX developer account and request API access so your organization can authenticate against the PEX API.

<Note>
  **Note:**

  **Important Note: To use the PEX API, your organization must have an active administrator account with PEX and be approved for API access.**
</Note>

To be approved for API access, please follow the steps below:

<Steps>
  <Step>
    Register for a developer account with PEX at [https://developer.pexcard.com](https://developer.pexcard.com/)

    * *Important Note:* You will need to provide the business name **exactly as it** **matches** the business name listed on the business settings screen on the administrator site
    * You will also need to provide the username for your API user. We recommend you create a new administrator account to use solely with the API. For details on how to create a new administrator, please see "[How to Create Business Administrators](/administrator-guide/how-to-create-and-send-a-new-administrator-invite) "
  </Step>
