#QUICKBOOKS TUTORIAL ESPANOL CODE#
Here is the code I cobbled together so far. Here is the code I am currently using to gain some simple functionality - creating the customer works fine (if the customer doesn't exist in qbo - this is something I need to check before adding - so any steer on that would be great also) I would of thought adding a sales invoice would be a pretty big thing to cover. Reading through the API documentation is confusing, and doesn't really offer any sample code. I cant believe no simple examples exist of this already - I guess not many are doing this via a desktop winforms application, or I am just looking in the wrong places - or have missed something obvious! It cant be that hard - so I'm really kicking myself at the moment.Īny help, or sample to set me in the right direction would be appreciated.
#QUICKBOOKS TUTORIAL ESPANOL HOW TO#
I have found next to no examples online on how to do this from a c# winforms application. I am constantly getting a 'Bad request' error. The next step, which has stumped me for the last 2 or so, is to be able to create an invoice for a customer - I just cant seem to figure out what to do. I can also create customers from the winforms application, and they appear in QBO - also great! I can now authorise and connect to my QBO sandbox account - great! So, my first hurdle was the OAuth - which eventually I managed to figure out. It seems intuit say this is the way to go, as all over APIs are net, as a winforms application to code theįunctionality I need (this allows me to have the functionality integrated in theĬurrent system, a this is also written in c#. NET SDK was the one to use, for two reasons. Return credit balances (not even tried this yet)Īfter reading a few forums, and articles to come to the understanding the QBOV3.
