$30-250 AUD

Paid on delivery
I am looking for a C# developer who can fix the functionality of my application. Specifically, the issue lies in the integration with other systems. I have access to both the source code and relevant documentation, which should make the task easier. The ideal candidate should have experience in C# development. I have a C# application that exports sales out of ebay and puts them into MYOB, this has been working up until December 2022 to which authentication started failing. This could be as simple as generating a new token or re-authenticating the API access, but i'm unsure how to do this. At some stage, i would like the C# application converted into an Azure Web app, but this is in the future.
