Step By Step: Accepting Checks via Telecheck, Payeezy & Direct API (.NET)

This is a very basic tutorial on dealing with Payeezy, who’s documentation I found sometimes difficult.  Some of this guidance, I only found in forum threads and so I document…

Using Async, Await, Plus a Slight Delay

Today’s problem dealt with how we view our invoices online.  We use an app on the iSeries that creates a PDF and delivers it to a set destination.  That destination, in our case is a regular windows server, the files landing in a small site:   pdf.mycompany.com.

My initial approach was simple, use the PHP API I have sitting on the iSeries to make a call to the program – passing it the parameters for that specific invoice, await response (which gave me the new created filename) and then redirect to that URL.  The method looks something like this:

[HttpGet]
public async Task<ActionResult> GetInvoiceAsync(int invoice)
{
    GetInvoice getInvoice = new GetInvoice();
    var client = new HttpClient();

    string fileName = await getInvoice.LoadPDF(invoice);

    string url = "http://pdf.mycompany.com/";
    url += fileName + ".pdf";

    return Redirect(url);
}

 

This worked great… 90% of the time, but the other 10% of the time, I clicked too quickly on an invoice and got forwarded to a 404.…

ASP.NET Core – Easy Transition of Bower to NPM

UPDATE (Oct 16, 2018):  I now rely on Libman for my front end management.  I use its 3 different providers to grab the libraries off of cdnjs, unpkg (supposed to include all npm) and filesystem for local files.  See post:  Using Libman Providers to Coral Front End Libraries

I love me some Bower, even with the shadow looming over it that it’s time is done.  Recently, though, it started to do something weird with just restoring/replacing packages that really began to cause problems with my project (and make for some seriously messy 99* commits).

I can do simple task running, etc but still very much a noob to packaging.

Here was my easy solution for removing Bower and switching over to NPM (and accessing those packages through Views).…

.NET Core with PayTrace (Mime Type Fix)

This year I am re-writing my previous payment solution (from PHP to .NET) and first on the project list is credit cards.  We are using PayTrace and their client-side encryption as to not have to worry about PCI Compliance.

I’m to the point where I have a Pre-Payment model with all the fields needed to send via JSON.  I also have a method to request a token for sending (uses demo username and pass) and a test PEM file I downloaded from the PayTrace site.  I also got the webpage scanning credit cards, and I hit submit and.. I get this:

XML Parsing Error: no element found

This is appearing in the console of Inspector in Firefox.  Turns out this a generic error Firefox throws out when it’s expending a file but gets nothing.

My path’s are correct, but the “public_key.pem” file is not attaching to my post.   The problem?  MIME-type.…
