This library provides simplified access to the GuideStar APIs.
Here is our getting started guide. This will help you get your API Account and Subscription keys which are necessary to use the SDK.
GuideStar SDK is available on NuGet:
PM> Install-Package Candid.GuideStarAPI
or if using .NET Core:
dotnet add package Candid.GuideStarAPI
At the most simple level, calling an API requires initializing the system with an API key, then calling the correct method from the resource you are interested in.
The majority of our resources use an EIN (Employer Identification Number) as a key for documents.
The following code will return the Premier JSON document of an EIN as a string.
GuideStarClient.SubscriptionKeys.Add(Domain.PremierV3, PREMIER_KEY);
var premier = PremierResource.GetOrganization(EIN);All request methods have an asynchronous and synchronous version.
GuideStarClient.SubscriptionKeys.Add(Domain.PremierV3, PREMIER_KEY);
var premier = await PremierResource.GetOrganizationAsync(EIN);All Premier responses are defined in our API documentation found here.
Similarly, the following code will return the Charity Check JSON document of an EIN as a string.
GuideStarClient.SubscriptionKeys.Add(Domain.CharityCheckV1, CHARITYCHECK_KEY);
var charitycheck = CharityCheckResource.GetOrganization(EIN);All Charity Check responses are defined in the API documentation found here.
The Essentials resource takes a search payload as input and then behaves similarly to our other resources. For all realtive search filters allowed in the payload, please refer to the code example below and refer to the API documentation found here.

var essentials = EssentialsResource.GetOrganization(payload);The return is a JSON collection of organization info that matches the payload parameters. All Essentials responses are defined in the API Documention found here.
There is a demonstration website in ASP.NET Core MVC to show example usage of the SDK.
