PayPal for Webservices API

Guidance for established merchants migrating to the new PayPal platform

Trust Payments has recently added support for integration with PayPal's latest platform. This is to ensure continued compatibility with new PayPal features and enable a more streamlined onboarding process for new merchants.

Established Trust Payments merchants who are already transacting with PayPal will be required to take the following steps to continue using PayPal going forward:


  1. You will need to be onboarded onto the new PayPal platform. This is a simplified process where you will be emailed a link to agree to new terms and grant Trust Payments the permissions needed to link to your PayPal account.

  2. PayPal mandates that you update the ORDER request submitted to our API to include additional information on all products in the customer's order.

    Each ORDER request will now require the following fields to be submitted:

    • products containing an array of JSON objects, each containing the following fields for each product in the customer's order:
      • productmainamount - The price per product.
      • productcurrencyiso3a - The currency associated with the product price.
      • productquantity - The quantity of the product in the order.
      • producttitle - The name of the product.

      For full field specifications, please select between the ECM and ECS tabs below and scroll to the relevant section describing the request/response you need to work with.

    Merchants operating in certain sectors that PayPal deems to be high risk will also need to update the ORDER request to submit the following additional fields:

    • The products array above must also include the following additional fields for each product in the customer's order:
      • productcode - The Stock Keeping Unit (SKU) of the product.
      • productdescription - A description of the product.
      • producttaxmainamount - The tax applied to the product.
      • producttaxcurrencyiso3a - The currency associated with the tax applied.
      • producttype - Choose a product type from "digital", "physical" or "gift".
    • paypaltransactionriskcontextdata containing an array of JSON objects, each containing the fields paypaltransactionriskcontextdatakey and paypaltransactionriskcontextdatavalue.

     

  3. You can now submit the shipping amount to Trust Payments during the checkout process.

    • If you know the final shipping amount at the start of the order, this should be submitted in the ORDER request using the customershippingbaseamount field. Doing so provides the customer with a better user experience by displaying the shipping amount on PayPal's website before they agree to the purchase.
    • If you are using ECS flow, you can parse the ORDERDETAILS response for the customer's delivery address and use this to calculate the shipping amount. This can then be submitted in the AUTH request using the customershippingbaseamount field.
    • Remember that while submitting the shipping amount is recommended, it is not required. For example, you won't be forced to submit a shipping amount for digital purchases that don't require shipping.

  4. When parsing the ORDERDETAILS response, you will need to be aware that the PayPal address and payer status is no longer verified on the new platform (these checks have been deprecated), and as such paypaladdressstatus will always return "Unconfirmed" and paypalpayerstatus will always return "unverified".

  The overall flow of requests sent / responses received remains unchanged. This allows you to make updates to your existing implementation without the need to start from scratch.

  We recommend you first deploy these changes to a staging environment and test your integration before deploying to a production environment. As part of this process, your test site can be configured to connect to PayPal's sandbox environment to more accurately represent the customer journey while testing.


In particular, you should ensure you understand the new Pay Later options that can now be displayed when the customer is redirected to PayPal and ensure your solution accounts for this.

We support two PayPal transaction flows:

  Express Checkout Mark (ECM)   Express Checkout Shortcut (ECS)

  Use the tabs above to change the workflow.

The below covers Express Checkout Mark (ECM)

Express Checkout Mark (ECM) - PayPal is shown as an additional method of payment on your existing checkout, alongside credit/debit cards.

CW68-EN.png

  • During the checkout process, your website presents PayPal as a payment method.
  • The customer selects their preferred delivery address on your checkout page and opts to pay using PayPal.
  • The customer is redirected to PayPal, where they sign in using their PayPal credentials (they can register with PayPal if they do not already have an account).
  • The customer reviews their order and agrees to the payment on PayPal’s website.
  • The customer is redirected to your website, where a confirmation is displayed (e.g. “Payment successful”).

  Pay Later

During the time that the customer's browser has been redirected away to pages hosted by PayPal, PayPal is in control of the checkout experience. To enable customers to spread the cost of larger purchases, PayPal may display additional finance options for transactions that meet their requirements to do so.

First steps

  

 

  Requirements

  • Before you can process live PayPal transactions, you will need to have a PayPal Business Account. If you do not already have a Business Account, you will be prompted to register a new account as part of the onboarding process we outline below.
  • PayPal does not support their hosted pages being rendered within an iframe. Instead, you must always redirect the customer's browser to PayPal during the checkout session.

  For some industries (such as Travel, Gaming and Events), PayPal requires additional information called Set Transaction Context (STC). Such information can be included in your requests to Trust Payments and these will be passed onto PayPal as necessary. Please contact our Support Team for further information.

  PayPal onboarding

  1. Contact our Support Team and enquire about enabling PayPal on your TRU Connect account.
  2. Our Support Team will provide you with a URL to complete the setup.
  3. Navigate directly to the URL in your browser and sign in with your PayPal Business Account.

      If you haven't already registered a PayPal Business Account, you will be prompted to do so as part of onboarding.
  4. You will be presented with a list of permissions that you will need to grant us in order to complete the setup. Read these carefully and click "Accept" to continue.
  5. After you have granted the necessary permissions, PayPal will perform additional verification checks on your account. If you have not already done so, you then may be prompted to validate the email address associated with your PayPal account.
  6. Once the above has been performed, a request will automatically be sent from PayPal to Trust Payments to activate PayPal on your site reference and the boarding process is complete. We will confirm via email when your site reference is enabled to process PayPal transactions.

      If you have any queries regarding the status of your PayPal onboarding, please contact our Support Team.

  Overview of ECM

  1. Initiate the customer
    • Customer enters their preferred delivery address on the merchant's website and selects to pay with PayPal.
    • Merchant submits ORDER request to initiate the session, including cancelurl and returnurl.
    • Merchant receives ORDER response, including paypaltoken and redirecturl.

  2. Redirect to PayPal
    • Merchant redirects the customer's browser to the redirecturl, including the paypaltoken.
    • Customer signs in and confirms their preferred delivery address and payment method on PayPal’s website, and agrees to perform the payment.
    • If successful, the customer's browser is redirected to the returnurl.
    • If the PayPal order is cancelled, the browser is redirected to the cancelurl where an error message can be displayed. We recommend that alternative payment methods are displayed, allowing the customer to try again.

  3. Process the authorisation
    • Only if the above has been successful, the merchant submits combined ORDERDETAILS and AUTH request to process the payment.
    • Merchant receives ORDERDETAILS AUTH response and displays receipt page to the customer.

  4. Payment completion
    • Under default behaviour, the transaction is in a pending state and funds will typically settle within 24 hours.

    • But if preferred, merchants can configure their setup to instead request funds are settled immediately. Or alternatively, settlement can be deferred for up to 7 days.

    • Once settlement has been completed, Trust Payments will submit a URL notification (if enabled) to the merchant’s system as confirmation. Merchant receives the notification and responds to inform Trust Payments the notification was received successfully.

 

1. Initiate the customer

 

 

  Displaying PayPal on your checkout

The official PayPal acceptance mark must be presented with equal prominence and close proximity to other payment types on your details page. No payment type should be selected by default.

CW70.png

You can download the latest official PayPal acceptance mark images from this URL:
  https://www.paypal.com/uk/webapps/mpp/logo-center (link to external site)
Upon selecting PayPal, card payment fields must be disabled or hidden from view.

Processing ORDER

  The ORDER request is used to initiate the order with PayPal.

When the customer chooses to pay with PayPal, your system will need to perform an ORDER request and interpret the response returned.

 You can configure your PayPal account to disable the check on duplicate invoice IDs (values submitted in the orderreference). Contact PayPal Support for further information.

 

2. Redirect to PayPal

 

 

After successfully submitting an ORDER request, your system will be returned a redirecturl in the response. To process the payment, your system will need to use this URL when redirecting the customer’s browser to a page hosted by PayPal.

By amending the URL as described below, you can change the text shown on the submit button displayed to the customer on the PayPal details page:

To display this button:

CW65-EN.png

Use the redirecturl unchanged.

To display this button:

CW66-EN.png

Add useraction to the endpoint as follows:
[redirecturl]&useraction=commit


After signing in to their PayPal account, the customer has the option to continue with the transaction or to cancel.

You must wait for the customer to return from PayPal to the returnurl hosted on your servers before processing an authorisation.

  When PayPal declines a transaction while the customer is on their servers, a message will be displayed on-screen. The customer may be prompted to try again or cancel the payment attempt.

  When testing, at this stage you will be redirected to PayPal's sandbox, an environment that closely resembles the interface the customer would use to sign in to their PayPal account and authorise the payment.

 

3. Process the authorisation

 

 

  If customer is redirected to cancelurl, allow customer to retry or select another payment method.

  If customer is redirected to returnurl, follow the instructions below.

  • The ORDERDETAILS request is used to retrieve changes made by the customer on PayPal prior to performing the AUTH.
  • The AUTH request is to process the payment.
ORDERDETAILS AUTH request (ECM)

This example demonstrates how to process an ORDERDETAILS followed by an AUTH request. Notice how the structure of the request is similar to that of a standard AUTH request, except “ORDERDETAILS” is included in the requesttypedescriptions field before “AUTH”.

Python PHP cURL Raw JSON Raw XML
#!/usr/bin/python
import securetrading

stconfig = securetrading.Config()
stconfig.username = "webservices@example.com"
stconfig.password = "Password1^"
st = securetrading.Api(stconfig)

orderdetailsauth = {
"parenttransactionreference": "72-32-20002",
"paymenttypedescription": "PAYPAL",
"requesttypedescriptions": ["ORDERDETAILS","AUTH"],
"sitereference": "test_site12345"
}

strequest = securetrading.Request()
strequest.update(orderdetailsauth)
stresponse = st.process(strequest) #stresponse contains the transaction response

4. Payment completion

 

 

  Settlement

By default, once a PayPal transaction has been authorised, funds will typically be settled into your bank account within 24 hours:

  1. Following authorisation, the Settle status is set to 0 to indicate settlement is pending.
  2. On a daily basis, Trust Payments initiates the settlement process for pending PayPal transactions.
  3. The Settle status of a PayPal transaction is updated to 10 when settlement is in progress.
  4. Shortly afterwards, Trust Payments receives confirmation from PayPal that funds have been settled and the Settle status is updated to 100.

  About Pay Later

When handling order enquiries from customers, please remember that a customer may have opted to spread the cost of the purchase via PayPal's Pay Later products.

Regardless of how the customer chose to fund the transaction, you will always be paid in full at time of purchase, as with a conventional PayPal transaction.

As a result of this, a PayPal transaction can be recorded as "Settled", even if the customer has not yet settled their balance with PayPal. Any issues that have arisen relating to interest-free credit or pending instalments must be taken up with PayPal directly by the customer.

 

Alternative settlement flows

Deferred settlement

To defer settlement on a given PayPal transaction, include settlestatus=2 in the ORDER request. This will be inherited by the AUTH request, which triggers the temporary suspension of the transaction following authorisation.

The settlement is deferred until you submit a TRANSACTIONUPDATE with settlestatus=0.

  PayPal transactions can be deferred for up to 31 days.

Immediate settlement

  Immediate settlement functionality is subject to additional requirements.

Before processing immediate settlement, you must contact our Support Team and request for this to be enabled on your account.

To enable immediate settlement for a given transaction, include settlestatus=100 in the ORDER request. This will be inherited by the AUTH request, which will trigger Trust Payments to attempt the settlement of funds immediately after authorisation.

If PayPal needs more time to perform checks, the transaction may be temporarily set to Settle status 10.

Partial settlement

You can opt to settle a lower amount than was originally authorised. To do so, submit a TRANSACTIONUPDATE with a lower settlebaseamount.

  Notifications

Before you begin testing, we recommend that you contact our Support Team and request that rules are enabled on your account, which submit URL notifications to your system in the following scenarios:

  • When a payment is authorised (AUTH has errorcode=0).
  • When funds have been settled (AUTH in settlestatus=100).

  When contacting Support, please provide your site reference and the endpoint to which the notification will be sent.

You will need to check the contents of each notification received and respond accordingly by following the processes outlined in our URL notifications documentation. In particular, you will need to look at the updated settlestatus value:

  • On authorisation: If the settlestatus is “0”, “1” or “10”, the payment has been authorised and you are not required to take further action at this time. However, values of “2” or “3” indicate funds are not scheduled for settlement (deferred and cancelled, respectively).
  • On settlement: If the settlestatus has been updated to “100”, this indicates that the funds have been settled. Alternatively, if this has been updated to “3”, this indicates there has been a problem and the payment was subsequently cancelled.

  Refunds

The process of processing PayPal refunds is the same as refunding a standard card transaction, but please first review the following:

  • To ensure your records with Trust Payments remain in sync with Paypal, we strongly recommend that you perform refunds exclusively using the Trust Payments platform, rather than through the PayPal admin portal.
  • You must ensure you refund the AUTH request, and NOT pass through references to any related ORDER or ORDERDETAILS requests.
  • Most PayPal refunds are settled immediately (settlestatus=100). However, under certain conditions defined by PayPal, refunds can be set to settlestatus=10 (“settling”), which is an intermediate step prior to settlement. If a PayPal refund on your account is in settlestatus=10, it is recommended you query it with our Support Team in case further actions need to be completed to ensure settlement.

  About Pay Later

When handling refund enquiries from customers, please remember that a customer may have opted to spread the cost of the initial purchase via PayPal's Pay Later products.

Because of this, it is imperative that when performing a full refund of a transaction, you should refund for the full amount to ensure the customer is not later billed for any funds still outstanding on credit.

When a refund is performed, the funds are debited from your bank account and PayPal is responsible for ensuring the customer is credited accordingly.
