Building a Charity Search App in C# Using the OrgHunter Charity API

Here’s a guide on how to use the OrgHunter Charity API to create a C# charity search application:

Step-by-Step Guide

1. Get an API Key: Sign up at OrgHunter Charity API to obtain your API key, required for accessing the API.
2. Set Up the Project:
   • Open Visual Studio and create a new Console Application.
   • Add System.Net.Http for HTTP requests.
3. Create the Charity Search Function: Define a function to send a POST request to the API endpoint:

using System;
using System.Net.Http;
using System.Threading.Tasks;

namespace CharitySearchApp
{
class Program
{
private static async Task SearchCharities(string searchTerm)
{
string apiKey = "yourKey";
string url = $"http://data.orghunter.com/v1/charitysearch?user_key={apiKey}&searchTerm={searchTerm}";

using (HttpClient client = new HttpClient())
{
HttpResponseMessage response = await client.PostAsync(url, null);
if (response.IsSuccessStatusCode)
{
string responseBody = await response.Content.ReadAsStringAsync();
Console.WriteLine(responseBody);
}
else
{
Console.WriteLine($"Error: {response.StatusCode}");
}
}
}

static async Task Main(string[] args)
{
await SearchCharities("humane society");
}
}
}

1. Test the Application:
   • Run the application and view the output.
   • Modify parameters like searchTerm, city, and state for different searches.
