Welcome to the Datatrans API reference. This document is meant to be used in combination with https://docs.datatrans.ch. All the parameters used in the curl and web samples are described here. Reach out to [email protected] if something is missing or unclear.

Key concepts

Transaction flow

The below steps describe a basic way of how a transaction flow with Datatrans can work:

  1. Redirect the customers browser to the Payment Page by submitting the mandatory parameters

  2. The customer enters their payment details and presses the Pay button.

  3. The transactionId and other important parameters will be sent to your Webhook (POST URL). Store them in your DB. In addition, all the parameters will also be sent to your success/cancel/error URLs.

  4. The browser will be redirected to the success/cancel/error page.

  5. Use the transactionId to perform different actions like Status cancel, credit and settle

Checkout the Payment processes chapter where all the possible actions which can be done after receiving a transactionId are explained in more detail.

Parameter format description

When describing response and request parameters throughout the reference, the following values are used for the parameter format.

Value Description Example

N

Numeric value

1337

DN

Decimal number

13.37

A

Alphabetic value

ABC

AN

Alphanumeric value

Abc-1337

MM

Month

03 (for March)

YY

Year

11 (for 2011)

N8

Numeric value of length 8

13371337

B

Boolean value

true

The uppTransactionId parameter

Once you do an authorization with an existing alias or by using the one of the integrations the uppTransactionId parameter is returned. The uppTransactionId parameter is needed for all subsequent actions after an authorization. Make sure to save it in your local database.

Parameter Format Description

uppTransactionId

N18

Unique transaction identifier

The reqtype parameter

The reqtype (request type) parameter is used to specify which type of action should be performed on Datatrans side. The different API endpoints support different reqtypes. For Authorizations (Server to Server or by using the Payment page) the following reqtypes are possible:

reqtype Description

NOA

Only authorization should be done. The amount will be blocked and a separate settlement needs to follow in order to actually charge the customer. Not all payment methods support splitting authorization and settlement. Refer to the documentation of the corresponding payment method if Deferred Settlement is possible.

CAA

Direct debit. Authorization with immediate settlement.

SCN

Only a pre-screening request should be done. Not all payment methods support pre-screening requests. Refer to the reqtype request parameter documentation for the particular payment method to see if pre-screening requests are supported.

When using Redirect Mode or Lightbox Mode and the reqtype parameter is not submitted for each transaction, the value configured in the Webadmin Tool will be used.

Reqtypes

In the image above, for both Visa and MasterCard reqtype CAA ('Direct Debit' radio button) would be used. Select 'Authorization / Settlement' if a deferred settlement is the preferred way of integration.

For authorizations with an existing Alias, deferred settlement, cancel and credit other reqtypes apply since they all share a common API endpoint

Transaction status

During the lifecycle of a transaction the status of a transaction changes. Based on the current status of a transaction, different actions can be performed. The following table describes all states for a credit card transaction.

Status Description Possible actions

Verified only

This status can be reached when using the Split Mode integration and finalization of the authorization did not yet happen.

status

Authorized

The amount given in the authorization is blocked/reserved.

settle, cancel, status

Card checked

When using the Validate API, a "card check" against the Acquirer is being made. No amount is blocked. For credit cards, this status means that the card number, expiry and CVV were validated by the acquirer.

status

Settled

The transaction is ready for transmission to the Acquirer.

This transaction status is reached automatically if <reqtype>CAA<reqtype> is used.

cancel, credit, status

Settled credit

The same as status Settled but for Credits.

cancel, status

Settled+credited

An already settled transaction was credited and waiting for transmission to the Acquirer. Note: Also partial credits are possible.

cancel, status, credit

Settled/Transmitted

The transaction has been transmitted to the acquirer. Cancels are no longer possible.

status, credit

Canceled

The transaction was canceled by the customer (for example Payment Page cancel button).

status

Declined

The transaction was declined by the Acquirer or another error occurred.

status

The Status API can be used to check the status for a transaction.

Mandatory parameters

In general the following parameters must be provided as a minimum when using one of the Integrations or making an authorization with an existing alias.

Parameter Format Description

merchantId

mandatory

AN10

Unique Merchant Identifier (assigned by Datatrans during signup). Depending on your integration you might receive multiple merchantIds. For example: One for your mobile application and one for your web shop. Get a merchantId now and start using the APIs.

refno

mandatory

AN18

The merchants reference number. It should be unique for each transaction.

amount

mandatory

The amount of the transaction in the currency’s smallest unit. For example use 1000 for CHF 10.00. If the payment method supports it, amount=0 can be submitted when using either Redirect Mode or Lightbox Mode and the user should only be registered (saving the users payment method to a profile for example). Use <amount>0</amount> for validating an existing alias.

currency

mandatory

A3

3 letter ISO-4217 character code. For example CHF, USD

sign

mandatory

The sign parameter to be submitted with each request. Refer to Request signing for more details.

However, there are payment methods where additional mandatory parameters are needed. To see how to call the different APIs with parameters for a particular payment method, refer to the chapter of this payment method.

Authentication & TLS

Authentication to the APIs is performed via HTTP Basic Auth. Provide your merchantId as the basic auth username value. Login to Webadmin to enable server to server security under UPP Administrations > Security and generate your password.

This should not be enabled on a already productive merchantId.

Create a base64 encoded value of merchantId and password (most HTTP clients are able to handle the base64 encoding automatically) and submit the Authorization header with each request. For example:

base64(merchantId:password) = MTAwMDAxMTAxMTpYMWVXNmkjJA==
Authorization: Basic MTAwMDAxMTAxMTpYMWVXNmkjJA==

All API requests must be done over HTTPS with TLS 1.2.

Request signing

In addition to basic authentication for the server to server APIs, it is possible to sign the request when using Redirect Mode or Lightbox Mode. Datatrans will check this signature and returns an error if the signatures do not match. The HMAC key needed to sign your requests can be found within the Webadmin tool

Sign

Details on the sign calculation can be found here: https://docs.datatrans.ch/docs/security-sign

Production URLs

Please login to Webadmin on https://admin.sandbox.datatrans.com to find the production environment URLs under “UPP Administration > UPP Data > Service URLs”

Checkout the API usage chapter to see which endpoint must be used for each integration.

Payment processes

This chapter describes the request and response parameters for the common payment processes. The respective API calls can have additional request/response parameters depending on the payment method.

Authorization with an existing alias

To charge an existing credit card Alias the authorize API can be used. In the following example the card is getting charged CHF 10.00. The reqtype parameter is not submitted. Which means the default value reqtype=NOA will be used.

curl -v -X POST https://api.sandbox.datatrans.com/upp/jsp/XML_authorize.jsp \

Validate an existing Alias

An existing aliasCC can be validated at any time by submitting <amount>0</amount> to the Authorization with an existing alias API.

Only Credit cards and PostFinance support the validation of an existing alias.

Deferred Settlement

The Settlement request is often also referred to as “Capture” or “Clearing”. It can be used for the settlement of previously authorized transactions. The uppTransactionId is needed to settle an authorization.

Redirect Mode

The Redirect Mode is the easiest way to create a payment. It is best practice to not use an <iframe> when using the Redirect Mode. This is because not every payment method or credit card 3D Page support the use of an <iframe>.

The Lightbox Mode should only be used if the payment method selection page happens on the Datatrans Payment Page or if the customer needs to enter payment method details. For example, if you start a transaction by specifying paymentmehod=PFC there is no need to use the Lightbox Mode integration. As in this case, the customers browser would be redirected to the PostFinance website immediately without the Datatrans Payment Page in Lightbox Mode being displayed.

Secure Fields

The Secure Fields allow you to securely collect card data by injecting iframes to your DOM. A separate iframe for both, card number and CVV code is used. Thereby, sensitive data never touches your server and allows you to capture all other related card data such as cardholder name, expiry date, etc. directly by yourself. The integration effort is higher compared to Redirect Mode or Lightbox Mode. However, Secure Fields are giving you the most flexibility when implementing your checkout flow.

Webhook (POST URL)

If configured in the Webadmin Tool, the Webhook (POST URL) will be called for each web transaction. We highly recommend to implement a Webhook (POST URL) listener in order to have more control about a transaction in scenarios where the user closes his browser for example.

The Webhook (POST URL) will be invoked whenever Datatrans tries to do an authorization with the payment method provider. As an example: The Webhook (POST URL) will be called after a successful or erroneous authorization with a credit card acquirer.

2 A success or error element.
3 A userParameters element for parmeters which where sent when the transaction was started.

success/cancel/error URLs

The result of a web payment transaction using Redirect Mode or Lightbox Mode is either success, cancel or error. Datatrans makes a HTTP POST request with Content-Type: application/x-www-form-urlencoded to the specified URLs. The URLs can either be configured in the Webadmin Tool or can be sent for each transaction:

Parameter Description

successUrl

This parameter represents the URL of the merchant’s web shop, where the consumer should be redirected to after a successful transaction

cancelUrl

This parameter represents the URL of the merchant’s web shop, application, where the consumer should be redirected to after cancelling the transaction.

errorUrl

This parameter represents the URL of the merchant’s web shop, application, where the consumer should be redirected to after a failed transaction

Common parameters

The Redirect Mode, Lightbox Mode and Authorization with an existing alias APIs share common parameters. Note, not all payment methods have support for them. For example PostFinance does not support shipping details. Refer to the payment method, if a specific object is supported. Common objects can be sent together. So if the payment method supports it, the uppCustomer* parameters can be used together with the uppArticle* parameters for example.

When doing a server to server authorization, those common parameters can be submitted in the following way inside the <uppCustomerDetails> element.

<?xml version='1.0' encoding='UTF-8'?>
<authorizationService version='4'>
  <body merchantId='1000011011'>
    <transaction refno='749532'>
      <request>
        <!-- other mandatory parameters here -->
        <uppCustomerDetails>
          <uppCustomer*>
          <uppArticle*>
          <uppFee*>
          <uppShipping*>
        </uppCustomerDetails>
      </request>
    </transaction>
  </body>
</authorizationService>

Where for example uppCustomer* could be uppCustomerFirstName. Check the following sections to see all available parameters for uppCustomer*, uppArticle*, uppFee* and uppShipping*.

If one of the Integrations is used, those parameters can be sent as form post or query string parameters for the Redirect Mode or as data attributes when using the Lightbox Mode. For Secure Fields the parameters can be submitted to the final split call.

Customer details

Whenever the payment method supports customer details, the uppCustomer* parameters can be used. If a particular parameter is required varies from payment method to payment method. For example the parameter uppCustomerBirthDate is not mandatory for each payment method supporting the uppCustomer* parameters.

Parameter Format Description

uppCustomerDetails

AN100

For web transactions using one of the Integrations:

yes, if the sent customer details parameters should be stored in the Webadmin Tool, or return (only available for PayPal) – if address details should be returned from PayPal to the merchant.

For server to server authorizations the Common parameters are placed inside the <uppCustomerDetails> element.
