RedcapAPI 1.3.5

REDCap API Library for .NET

The REDCap Api Library provides the ability to interact with REDCap programmatically using various .NET languages(C#,F#,VB.NET);

Prerequisites

1. Local redcap instance installed (visit https://project-redcap.org) if you need to download files(assuming you have access)
2. Create a new project with "Demographics" for the template; this gives you a basic project to work with.
3. Create an api token for yourself, replace that with the tokens you see on the "RedcapApiTests.cs" files, and others
4. You'll may need to add a field type of "file_upload" so that you can test the file upload interface of the API
5. Build the solution, then run the demo project to see the results.

2. Add reference to the library in your project, or download from nuget into project
3. Add "using Redcap" namespace
4. Add "using Redcap.Models" for convenience
5. Replace the demo api token with your test project or you can import the data dictionary in \Docs thats provided for convenience.

Sample / Example

using Newtonsoft.Json;
using Redcap;

namespace RedcapApiDemo
{
    internal class Program
    {
        static async Task<int> Main(string[] args)
        {
            var apiToken = "3D57A7FA57C8A43F6C8803A84BB3957B";
            var redcap_api = new RedcapApi("http://localhost/redcap/api/");
            var result = await redcap_api.ExportRecordsAsync(apiToken);
            var records = JsonConvert.DeserializeObject(result);
            Console.WriteLine(records);
            Console.ReadLine();
