Need a programmer to update Amazon API usage in C# program.

Closed Posted 10 months ago Paid on delivery
Closed Paid on delivery

We had a programmer write for us a program that accesses our unshipped orders on Amazon and arranges them into a .csv file that can be imported into our order management software (CMS Professional by New Haven Software). The program was written in C# in the Virtual Studio Code environment (ver 1.80.01) using .Net framework (ver 2.1.0).

At the end of August, Amazon is discontinuing Marketplace Web Service (MWS) API sections. We need a programmer who can take our existing program and update it so that it uses Amazon’s SP-API. It should function exactly as before, only using the new API.

Skills and experience required:

- Strong proficiency in C# programming language

- Extensive knowledge of the Amazon API

- Experience in updating and integrating API features

- Ability to identify and fix bugs and errors in the program

The client already has an existing Amazon API set-up, so familiarity with this is essential. However, there is no need for assistance with the user interface design of the program. The main focus is on updating the API features.
