Build a Website

We are looking for development of Web API projects that interact with certain cloud API's. This project is a first of many steps. Previous experience with the salesforce API is required. For this project, we are looking for an C# Web API controller that will interact with the [login to view URL] rest api for a credentialed user. A [login to view URL] dev environment can be provided if needed, but they are easy to setup yourself. Please use Visual Studio 2013 (Express is OK). Here are the API Controllers and methods to be built... 1) Please create an AuthorizationFilterAttribute class that captures the login name, password and token in the header and authenticate to force.com. On authentication, please set the first and last name of the user in a shared class for the current user. If not authenticated, return any authentication errors. 2) Create Get to pull all Account fields (It can be a short list of what is normally shown in the account [login to view URL] page) 2) With a PUT, accept the Account ID with company name and one custom string field. These would be update the Account record in force.com. For the custom string field, if it is not created for the OrgID of the user, it will ignore the update for that element. 3) Create Get to pull all main opportunity fields shown in the [login to view URL] page. 4) With a PUT, allow the opportunity amount to be edited. That is it for now. We will work with you on our coding approach and style to prepare for additional projects. The above is only helping us provide a foundation for additional requirements. thanks!
