I want to develop a .net service that will run on a schedule and query my company's campaigns for recently sent emails. This service will run completely independently of user input. I don't have our Constant Contact username and password but instead have the api key and access token that my colleague generated for me. Once the service is built and deployed, there will be no user input. Everything I read seems implies that OAuth is required but entering account details is not an option. It's important to stress that this is my company's account and will not be used in any way by third-parties. The service is (for all intents and purposes) the account owner but does not have login credentials. Can someone provide code samples as to how to go about this developing this?
