Consume from Client Side¶

ThinkGeo Cloud Reverse Geocoding does not allow anonymous users to access the API. Before working with these APIs, you will need to register with ThinkGeo Cloud and create your own clients. A new account comes with two clients: NativeConfidential and JavaScript. See more details at here.

ThinkGeo Cloud provides standard RESTful APIs which can be consumed on any platform through any language. ThinkGeo also offers two prepackaged API clients to make it easier to integrate into .NET and JavaScript applications.

SDK for .NET¶

Our .NET SDKThinkGeo Cloud Client makes it easy to consume all of the ThinkGeo Cloud services in your applications. It's available on NuGet.

At the NuGet Package Manager terminal, you can install this package by running the command: Install-Package ThinkGeo.Cloud.Client -Version VERSION_TO_BE_INSTALLED.

SDK for JavaScript¶

The SDK for JavaScript enables developers to directly access ThinkGeo Cloud services from JavaScript code running in browser. This SDK can be found at thinkgeocloudclient-js.
