Before you can integrate PayPal you will need an account with PayPal, if you don't yet have one then signup here.

Next login to Transporters and go to Settings->Financial->Online Payment Methods.

If the PayPal row says "Install" click that, otherwise click the edit icon.

You need a Username, Password and Signature from your PayPal account to setup the integration - these are NOT your normal login details!

Here are the steps to get your details:

1) Log in to your PayPal Premier or Business account.

2) On the main menu, click More, then Business Setup

3) Under payment setup, select "On your website", then continue

4) Choose "Option  A (Work with a partner that's already integrated with PayPal)", then click either "Setup API access" or "Get your API credentials", depending which is showing.

5) Scroll down to "NVP/SOAP API integration (Classic)" and click "Manage API Credentials"

Next step depends on whether you have previously created any API credentials.

6) If you see the screen below, then choose "Request an API signature" and then Agree and Submit.

7) Once you have credentials you will arrive at the screen below.

8) Click show on the api username, api password and signature and copy these 3 items into their corresponding boxes in your Transporters System.
Settings->Financial->Online Payment Methods->Paypal

Other Config Options


Allows you to charge your customers a surcharge (or even discount!) for PayPal transactions which can be used to offset the fee's that PayPal charges.


Publish - Available for customers to choose on your invoices when making a payment
Internal - Hidden from customers but available as an option for staff when entering payments manually
Disabled - Not available for customers or staff

Test Mode

Test mode allows you to make test transactions to ensure everything is working without needing a real credit card.

Your main account details will NOT work in test mode, you must register at and obtain a set of test credentials following the steps above to use test mode.

Solution Type

Optionally require all customers to have a PayPal account to make a payment. Most users prefer the more flexible first option that allows any credit or debit card to pay without a PayPal account.

Landing Page

Non PayPal account will default to asking visitors to enter their credit card details.
PayPal account login will default with a login to their PayPal Account.

Brand Name, images and colours

Customise the display of the payment page.
If entering custom image URLs make sure they are hosted securely with a link that starts with "https://"

Most common Issues

  1. Using paypal account login username and password. You MUST request and use your dedicated API username, password and signature as detailed above.

  2. Using test mode with live credentials. Paypal requires you to obtain a different set of credentials from in order to use their test mode. Remember to swap with live credentials when turning test mode off.
