Setting up Express Checkout with Email

For a quick start, Paypal Express Checkout requires you to specify your email only:


  • If you already have a Paypal account, then you should specify the email you created your Paypal account with.
  • If you do not yet have a Paypal account, then you can specify the email you are going to create your Paypal account with and create the account itself later on.

Setting up Express Checkout with API Credentials

For a full-fledged Express Checkout implementation allowing payments and post-checkout operations, you will need to use the API option:


After choosing this option, you will need to specify a set of credentials for access to the API.

To get a set of credentials please contact the PayPal support.

Two API options are supported: PayPal API and Payflow API. PayPal API (Merchant API) will work for most merchants. If you can, use PayPal API. If you only have access to Payflow API, then use Payflow API.

Your choice of an API solution will determine the type of API credentials that you will need to enter.

For PayPal API, you will need the following set of credentials:

  • Partner name (should always be “PayPal”),
  • API access username,
  • API access password,
  • API signature or API certificate (The Use PayPal authentication method box allows you to choose, which one you want to use).

The above named credentials can be retrieved in your PayPal account profile.

For Payflow API, you will need the following set of credentials:

  • Partner name,
  • Merchant login,
  • User,
  • Password.

These are the same credentials that are used as your login information.
