Overview

Pay Now eCommerce is a secure online payment service that can be integrated to receive payments. We offer 3D secure Credit Card payments via Mastercard, Visa, American Express, and Diners Club, Instant EFT, Bank EFT and Retail payments. Our Scan to Pay feature allows multiple wallets and banking applications to scan a single QR code for payment.

• Payment Request
• Pay Now Billing
• Pay Now QR/POS

Service set up process

• Specify the payment options you require on application for the service.
  • Issue a Pay Now service key on the Netcash account;
    • Choose the payment options and
    • Insert or select the postback URL’s.
  • NOTE: If you developing on behalf of a Netcash client, supply the client with the postback URL’s they need to insert in your NetConnector profile for you to consume before the transaction is processed.

Recommended Implementation Methodology:

• Develop the form POST method from your system with attribute target=”_top” to send the payment instruction to https://paynow.netcash.co.za/site/paynow.aspx to open the link in the full body of the current window.
• Alternatively, develop the form POST method from your system with no target attribute to send the payment instruction to open https://paynow.netcash.co.za/site/paynow.aspx in itself. ^{(NB! This method is not advisable due to cross-browser compatibility, especially for Microsoft Edge and Apple Safari browsers – read more)}

Credit Card transaction processing notice

Please take note that any new Pay Now eCommerce service has a default transaction limit of R100.00. If the transaction limit (ZAR value) is exceeded – Credit Card payment options will not display. Contact your Netcash Payments Advisor for assistance.

Pay Now payment methods

The payment methods available and descriptions on the Pay Now service are or see the visual representation here.

Read more about the different payment methods we offer.

Pay Now service key

The service key is used to authenticate access to the Pay Now service. It identifies the origin of the payment instruction. The service key determines the Netcash account to which the proceeds of the payment will be credited and what payment options are available to the customer.

NetConnector

The NetConnector profile settings allow customisation according to specific requirements:

• Active: Indicates the service setting.
• Email: This is the email address to which any errors in processing will be directed and also to which the service key will be sent. Notifications of transactions will also be received here.
• Service Key: This is the unique service key (field m1) which must be included in the POST to the Netcash URL.
• Allow Master and Visa payments: This option is used to control whether your client may pay by credit card.
• Accept url: Enter your accept URL here. If the URL changes for any reason, it can be updated on this page. This is the URL that the browser is sent to if the transaction is successful.
• Decline url: Enter your decline URL here. If the URL changes for any reason, it can be updated on this page. This is the URL that the browser is sent to if the transaction is declined.
• Notify url: This is the URL that Netcash will call for all transactions to indicate payment status. It is also used for offline transactions such as Bank EFT and Retail payments where the payment is not processed in real time. These payments will be posted when they are made and Netcash will notify your system through this URL.
• Redirect url: This is the URL that the browser is sent to once the complete button is clicked on the Bank EFT and Retail payment screens on Netcash. This could/would return the customer to your site while you are waiting for a payment to be made.
• Make test mode active: use this setting while you are testing the system to simulate transactions. Once your development is complete, this box should be un-ticked

Test Card Details

Use the following card details to test transactions. Please note: it is highly advisable to test transactions only if the service is in “TEST MODE” to avoid charges

Visa Successful
Visa Card Number	4000000000000002
Expiry Date	Any future date (MMYY)
CVC/CVV/CVD	123
MasterCard Successful
Master Card Number	5200000000000015
Expiry Date	Any future date (MMYY)
CVC/CVV/CVD	123
Visa Failed
Visa Card Number	4000000000000036

Configure

Pay Now service key variables:

Select ACCOUNT PROFILE -> NetConnector -> PAY NOW in your Netcash account to configure Pay Now variables.

Pre-defined postback URLs

The Pay Now configuration allows the configuration of pre-defined postback URL groups.

These postback URLs perform two (2) functions namely:

1. They send data back to the host system about the transaction, especially useful for real-time notifications/allocation of credits.
   1. Once the transaction is processed, the status and the transactional data of the payment gets redirected to two pages:
      1. The Notify URL always receives all the transaction data but it is not client-facing -and
      2. The Accept -or Decline URL depending on the transaction result
2. The Accept -or Decline URL redirects the person making the payment, to a visual display of the transaction status once the transaction is completed.

You will note a Redirect URL in the list as well. This URL is used for when the user click’s the CANCEL PAYMENT button on the payment page, or when the user selects a non-real-time payment; to remind the user of i.e. the payment reference to use.

Read more about pre-defined postback URL groups here.

Netcash allows ISV’s to use default postbacks for their clients by adding them to a dropdown list. This will minimize the risk of incorrect postbacks. It should only be used where all clients have the same postback URLs .

In the above example, Netcash will send the responses to the centralized server and the client simply selects the software from the drop-down list and Netcash directs the postback data .

POST to the Pay Now page:

The following data is required for the e-commerce payment gateway

• ^{If M21 = 1 then M22 and:}
• ^{M23 or M24 and M25 or M26 are compulsory}

These parameters are required by Pay Now when submitting a transaction. Although data is not mandatory for all the fields; all the fields must be passed in the form post.

Netcash will authenticate the Pay Now service key in field m1.
Only if the key is successfully authenticated, will the payer be directed to the payment method selection page.

^! Tokenization will not occur if the Pay Now profile is set to TEST MODE active.

Subscription billing is available for Visa -and MasterCard only.

TIPS

• * Add the purchaser’s name -and the order/invoice number in brackets after the description to easily identify the transaction on your Netcash statement without referencing Pay Now transaction reports.
• ** Add the debtor’s reference in this field, not displayed on the Netcash on screen statement, but is downloadable using the Netcash statement download.

Additional data

• See the recommended implementation methodology here.
• Ensure that the amount includes both decimals and no more than 2 N characters.
• Any data which you need to be returned in the Notify, Accept or Decline post should be included in m4, m5 or m6.
• Data in these fields will be returned in the Extra1, Extra2 and Extra3 fields of the post and in the export of your Netcash statement for reconciliation purposes.

IMPORTANT NOTE

Shopping Cart Plugins

Your Netcash account is already integrated into various free online shopping cart plugins and we also support customised integration.

Pay Now payment selections

The payer can choose from a multiple of payment options, as confirgured in the NetConnector profile on the Netcash account.

^{click image for a demonstration}

The payer selects the method of payment (credit card in this example) and is directed to the payment input page.

The payer is then redirected to the bank 3D Secure input screen where they enter the OTP sent to their email or mobile device to authorize the transaction.

If the payer selects Retail, the following is displayed which they can print, email or SMS to make a retail payment

When paying via BANK EFT the following is displayed to enable the payer to make a bank-on-bank EFT (selecting Netcash (PTY) Ltd as predefined bank beneficiary)

The EFT payment details are displayed with a unique deposit reference which must be used to make the EFT payment.

Notify, Accept, Decline and Redirect pages

After the transaction is complete, the data is returned to the respective pages which were configured in the Pay Now service key.

Read more about the Postback URL’s.

Should you place the gateway in “test mode“, the data will automatically be posted to the following url’s depending on transaction status unless you have set your own postback url’s.

• https://api.netcash.co.za/inbound-payments/pay-now/accept-response/
• https://api.netcash.co.za/inbound-payments/pay-now/declined-response/
• https://api.netcash.co.za/inbound-payments/pay-now/redirect-response/
• https://api.netcash.co.za/inbound-payments/pay-now/notify-response/

It is advisable that all developers reconcile (indicate payment status) from the data sent to the NOTIFY url.
Note: For subscription payments it is important to take note of the card expiry date as Netcash will cease running the subscriptions once the card has expired. Where a subscription card has expired, a new subscription will need to be obtained from the card holder

This URL is called for all transactions asynchronously.

Unlike Instant EFT and Credit Card services, delayed services like Retail -and Bank EFT do not call the Accept and Decline URL, however, all the payment type notifications are sent to the Notify URL.
Netcash will retry a number of times before it is noted as not received.
The Notify data should be used for system updates whereas Accept and Decline URL’s are to be used to synchronously update the Buyer on the status of the transaction.

TIP: Remove the [FromUri] attribute from your endpoint signature.

Acceptable URL Format

When the Accept, Decline or Notify URLs are called, any data provided in the M10 field will be appended to the URL. URLs that already contain query parameters are not supported and may lead to invalid URLs being formed. Do not include query parameters in the URLs using the query separator (“?” in the URL).

Netcash Pay Now appends a query separator (“?”) to the URL followed by the M10 field contents.

Example:

The M10 field can be used for any additional transaction identifying information. Ensure that the contents of the M10 field are acceptable URL query parameters.
Also consider using the Extra1 (M4), Extra2 (M5), Extra3 (M6) fields for similar information.

Notify URL

Data URL is form POST.

content-type:  application/x-www-form-urlencoded

Accept URL

Data URL is form POST.

content-type:  application/x-www-form-urlencoded

Decline URL

Data URL is form POST.

content-type:  application/x-www-form-urlencoded

Redirect URL

Data URL is form POST.

content-type:  application/x-www-form-urlencoded

Unpaid reason codes

Transaction trace

After your servers have received the transaction it is advisable to compare it with the original data sent. This can be done by sending a request that contains the ‘RequestTrace’ parameter to our servers which will return the transaction data to the calling service. Call: URL: https://ws.netcash.co.za/PayNow/TransactionStatus/Check?RequestTrace=114.228862205218 where 114.228862205218 represents the ‘RequestTrace’ parameter and it would reply with a JSON string with the data that would look like this:

{“RequestTrace”:”114.228862205218″,”Amount”:”4.00″,”TransactionAccepted”:false,”Reference”:”22″,”Reason”:”Invalid card number”}
