OrderTransactionsUpdate Endpoint


It wouldn't be unusual to need to update an existing transaction, but you should be careful when you do.  This endpoint allows you to update any specific transaction in your store.


The following pre-requisites will be necessary to accomplish the goals of this article:

  • General understanding of REST and API’s
  • Understanding of C# and/or JavaScript
  • Visual Studio 2012 or newer

Getting Started

You should already have a project open and ready to accept code to allow you to use this REST API endpoint.  You should also have one or more transactions created so that you can successfully find one to update.


This REST API endpoint allows you to update an order transaction in your store. This requires that you also have a transaction to update, which would mean that you should also call the OrderTransactionsFind endpoint to get an existing transaction.

Example URL

This is what the REST endpoint will look like if you are calling it using JavaScript.  See our REST API URL documentation for more information.


BVIN is the order transaction ID as described in the parameters below.

HTTP Method



Parameter Description
bvin This is the unique ID of the transaction that you wish to update
data You will need to pass an updated JSON version of the OrderTransactionDTO object in your post request


If successful, this endpoint will return a populated OrderTransactionDTO object in JSON format.  Otherwise, you should have one or more errors returned.  

Example Code

The following code will allow you to successfully call this endpoint, provided that you have enabled it.

        error: function (jqXHR, textStatus) {
            // do something else


function ParseDateForSave(dateValue) {
    // create a new date object in UTC format
    var newDate = new Date(parseInt(dateValue.substr(6)));

    // return the UTC version of the date
    return newDate.toISOString();
