How to create a Golang (Go) client to integrate with the snapWONDERS API

The purpose of this tutorial is to show you how you can create a Go client example to the snapWONDERS API. This includes a step-by-step guide how to set up your development environment, the example source code and instructions on how to test and run.

What is Go?

Go, also called Golang or Go language, is an open source programming language that Google developed. Software developers use Go in an array of operating systems and frameworks to develop web applications, cloud and networking services, and other types of software.

It is syntactically similar to C, but also has memory safety, garbage collection, structural typing, and CSP-style concurrency.


Through the example source, you will be able to:

  • Upload digital media (using resumable uploading following the Tus.io protocol)
  • Perform deep digital media analysis, reveal hidden metadata, hidden metadata, copyrights, steganography and private information leakage
  • Display the results from the analysis (in which you can extract and make use as needed)

Installation and setup

Development environment

For the development environment you will need:

  • Install Visual Studio Code. You can download and install from visual code studio
  • Install the Go programming language if you have not done so. Simply follow the instructions from go programming language
  • Install the plugin into Visual Studio Code called "Go". See image below for details:
    Go plugin


You will need the snapWONDERS API Key before you can get started:

  • Signup and create an account at snapWONDERS at signup. If you wish to create account via Tor or I2P then you can do so by accessing snapWONDERS via the Tor or I2P portals. For the dark web links visit browsing safely
  • Under your account settings, scroll to the bottom under the section "API Settings" and click the button to generate your Auth API key
  • Copy this key directly into the main.go file under the constant SNAPWONDERS_API_KEY

Source Code

The source code for these examples are located on GitHub - https://github.com/snapWONDERS/example-Go-client-to-snapWonders-API

Running the Go example

Once everything above is setup, and you've downloaded the source, you should be able to simply open the workspace folder with Visual Studio Code and run or debug it. Simply hit the default hot keys F5 to start debugging or to run directly use Ctrl+F5.

If you wish, you can change and provide your own digital media to upload (images and/or videos) and change the MEDIA_PATH_FILENAME constant contained in the main.go file. Otherwise the sample image provided is just a photo of me that I use on my social media accounts.

If all is well, then you should see the standard output to be something like below:
