With the API authentication you legitimate yourself as owner of a Paypal business account, which is allowed to access the API (advanced programming interface). There are two authentication methods:
  • API-Signature: Your account is being identified by a user name, a password and a unique combination of ciphers and character strings. API authentications on signature base do not expire, are easier to implement and are being used very frequently.
  • API-Certificate: Your account is being identified by a user name, a password and a certificate, downloaded from Paypal. API certificates are valid for three years and must be renewed before expiry. This method offers a maximum of security.

Watch the video on the right side in order to learn how you can obtain an API signature from Paypal.

KISS Advertiser can manage the Paypal methods Paypal Express and Paypal API-Signature.

Paypal Express is the fastest method to link your paypal account to KISS Advertiser. All you need is your username needed to login at Paypal. Usually it's your email address. Set up KISS Advertiser as follows:

  • Click "Payment Systems" in the Control Panel
  • Select "Paypal" from the list
  • Click on "Settings"
  • At "User info 1" enter your paypal login name (usually an email address).
  • Repeat this for Payments testmode as well
  • Important: Leave all other fields empty !

You do not need to enter your Paypal password as it is not needed for the receipt of payments. The fields for API Password and API Signature must be empty in order to enable KISS Advertiser to recognize that this is a Paypal Express account. Please note that you might use different User infos for real payments and payments testmode (called: Paypal sandbox). Most commonly Paypal uses the appendix -facilitator to your email address. E.g. if your email address is This email address is being protected from spambots. You need JavaScript enabled to view it.,  your Paypal sandbox address would be This email address is being protected from spambots. You need JavaScript enabled to view it.. Please keep in mind that the sandbox access requires a special password wich is different from your regular Paypal password.

Advantage of Paypal Express: Easy setup, no settings to make, quick integration.

Disadvantage of Paypal Express: The customer is redirected to the Paypal website where the payment will be managed. After this he will be redirected to the owner's website. However the owner has no real time control function whether the payment was made or not. In case of success, Paypal will redirect to a special success page, which can be configured and in case of fail it can be configured to redirect to another page. However this is not a payment confirmation the site owner can rely on. The owner must check his emails in order to verify the payment as Paypal sends the payment confirmation by email.
