Connect-E - Standard Repeat Payment

This section describes how to collect a customer's CV2 code in order to create a repeat transaction.

Process Flow

  1. Execute payment using either Connect-E Standard or Checkout.
  2. Collect the cross reference code from the get payment endpoint on the Connect-E REST API.
  3. Create an access token with a transaction type of SALE or PREAUTH and pass in the cross reference code.
  4. User loads the page with the JavaScript package, and the access token is passed in.
  5. iFrame is initialised to collect CV2.
  6. Once the payment form is filled out and the user clicks submit. The execute function is called and a JavaScript promise is returned.
  7. If 3D secure is required, a modal is displayed for the user to enter their details.
  8. The promise resolves with the outcome of the transaction, including status code and auth code.
  9. Confirm the status of the transaction via the Connect-E REST API

<div id="recurring-errors"></div>
<button id="recurring-test-pay" class="btn-primary btn pull-right" data-loading-text="Processing...">Pay</button>
<div id="recurring-demo-result" style="display: none">
    <h5>Payment Complete</h5>
        <dt>Status Code</dt>
        <dd id="recurring-status-code"></dd>
        <dt>Auth Code</dt>
        <dd id="recurring-auth-code"></dd>

Setup Connect-E Standard - Repeat Payment


The javascript is loaded in the same way as a one off payment, directly from our servers.
<script src=""></script>


To initialise an instance of connect-E Standard Repeat Payment call Connect.ConnectERecurringPayment and pass in the configuration object with an optional reference to a callback to handle validation errors.
var recurring = new Connect.ConnectERecurringPayment(config, displayErrorsCallback, onSubmitTriggered);
Parameter Description
required rootConfig
Config containing details of this payment and the styling of the repeat payment form.
displayErrorsCallback An optional callback to display text validation errors. The supplied function is called when there is a validation state change. This function is passed an array of validationError objects.
onSubmitTriggered An optional callback that is called when the submit event on the payment form is fired. This allows the payment to be submitted or extra validation done when the user presses the enter key on the payment form.

Validation Error

Property Description
The type of validation error that has occured. This can be either of the following: cv2Required, cv2Invalid
Message detailing the validation error for displaying to the user.

Execute Payment

To execute the repeat payment call executePayment on the object returned from the call to initialisation. This will consume the access token even if the payment is declined, another access token will need to be generated from the REST API and Connect-E will need to be reinitialized if another payment is needed. The promise will be rejected if there is an error returned by the server or if the transaction is already processing. The promise will still be fulfilled if the payment is declined (just with non 0 status code).
        /*handle response here*/
        /*handle failure here*/
When the promise is fulfilled the following object will be passed.

Transaction Result

Property Description
Indicated the status of the transaction. 0 for a successful transaction.
If the transaction was successful, then the auth code is passed out here.
This gives a more detailed description of the status of the transaction.

Status Code

Status Code Result Description
0 Successful The transaction was successful
3 Authorizing The card holder has not completed 3DS, this status will only be seen on the REST API.
4 Referred The card issuer has parked the transaction awaiting contact with the customer before proceeding to authorise or decline the transaction.
5 Declined The transaction was declined by the card issuer or acquiring bank.
20 Duplicate Transaction The transaction which was processed was a duplicate. Ensure each transaction has a unique OrderId.
30 Failed Error executing transaction.
40 Processing The transaction is currently being processed, please check status again. This status will only be seen from the REST API if called before the JavaScript promise resolves or the Webhook is called.
90 Revoked The access token was revoked while the cardholder was completing 3DS authentication. The transaction was stopped before being sent for processing.
99 Waiting Pre-execute The transaction has been paused pre-execution using the waitPreExecute flag; a call to resume the transaction is expected within 15 minutes.
400 Invalid Request The request has failed validation by our servers and the transaction has not been submitted to the gateway. Possible causes for this are invalid transaction type or other data in the request.
401 Issue with Access Token The access token being used is not valid, the transaction has not been submitted to the gateway. This can be caused if the access token has already been used or the 30 minute expiry time has elapsed.
404 No Access Token Supplied No access token has been supplied to Connect-E. Transaction has not been submitted to the gateway
500 Internal Server Error There's been an error submitting the transaction, please check the REST API for the status of the transaction.
