This is sample code to show you how to post to CyberSource web APIs. This sample is posting to the development environment at https://apitest.cybersource.com From this code, you will be able to create the request headers necessary for your calls to be authorized by CyberSource. There are some variations that needs to be adjusted for calls to other methods and HTTP verbs, but the hardest part which is creating the acceptable request headers is provided to you in this sample. If you're still stuck, read in more details at https://sarn.phamornsuwana.com/c-code-for-cybersource-rest-apis/
You will need to have your merchant Id, secret key, and key Id ready. Please put the sample JSON file in your project's bin directory.
The codebase is in .NET Core, since at this time (3/2019) the CyberSource Rest API SDK only works on the .NET Framework. I'm assuming, most people who will find this sample code useful are those on .NET Core, issues compiling the SDK along with their other NUGETs, deployment workflow or just prefer to utilize the web APIs directly. Please note that this code is ONLY for learning purposes and a proof of concept. It is NOT production ready code. Please refactor accordingly.
