Get started with Uphold Sandbox

The Uphold Sandbox is a development environment for building and testing applications. The Sandbox does not use real money.

How it works

Getting started

To begin, create an account in the sandbox environment. Your sandbox account will be in no way connected to your live account and can be used safely without the worry of affecting your production account.

Verify your account

To complete the registration process, you will need to verify your email address and phone number. When verifying your phone number in the sandbox environment, use the verification code "000000" when prompted to do so. No SMS will be sent to your phone.

Add fake funds

You can add funds to your sandbox account using any bitcoin testnet "faucet," which dispenses "fake bitcoin" to assist in development. We recommend using the following faucet.

Connect your application

To connect your application, login to the sandbox environment. In the top right hand corner you will see a profile icon. That is where you will find the drop down menu where you can select ‘applications’. You will be taken to a page where you can register a new application and obtain a ClientID and ClientSecret.

Build, hack, have fun

When connecting your application to the sandbox API, please use the following base api-sandbox.uphold.com.

What is the Sandbox?

The Uphold Sandbox is a development environment for building and testing applications built on top of the Uphold Platform.

The Sandbox does not use real money.

Step 1: Create an account

To begin, create an account in the sandbox environment.
Your sandbox account is a test account for testing applications built on the Uphold platform and is not in any way connected to your official Uphold account. The sandbox account should have a separate username and password and can be used safely to test without impacting your Uphold account.

To signup for a sandbox account visit our sandbox homepage.

Step 2: Verify your account

To complete the sandbox registration process, you will need to verify your email address. This email address should not be the same as that associated with your live Uphold account.

Step 3: Fund your account

You DO NOT need to send value from your Uphold account to your sandbox account for testing.

You can utilize funds from the testnet faucet. The bitcoin testnet provides developers with, 'fake bitcoin' to assist in the development of new applications. We recommend using the following faucet for testnet funds:

We ask that you adhere to standard testcoin etiquette. Don’t take more coin than you need
and be sure to return the coin you took once you have finished running your tests. This coin cannot be used outside of a sandbox environment.

Step 4: Connect your application

Navigate to Settings > Applications > Developer Applications > "register Application", and input the following information:
- Name: An application name
  Example: ‘Really Awesome Bitcoin App’
- Site URL: The application website
  Example: https://reallyawesomebitcoinapp.com
- Redirect URL: A callback URL for receiving an authorization code, as per the OAuth2 authorization flow (must be https://)
  Example: https://reallyawesomebitcoinapp.com/connect
Select the Scopes (permissions) of the application.
Select "I accept the Developer Agreement" followed by "Register".

Your client ID and Client Secret Tokens will be automatically generated. These codes are necessary for generating authentication tokens.

When connecting your application to the sandbox API, please use the following base URL:
https://api-sandbox.uphold.com

In an effort to better protect and to keep our customers safe, we review every application developed on our platform prior to it being released to the public. We evaluate applications for quality, user experience, and security.

The first step to register an application in production and obtain the API Keys is to create a business account with Uphold. Sign up for an account and click "business" when prompted to get started. If you'd like to talk with someone on our team about a business account and the benefits you'll see, send a note to [email protected] and we're happy to help you out.

We recommend you develop your application in our sandbox environment first. Our sandbox environment uses testnet value and is free of all restrictions – allowing developers to freely develop and test their products, and evaluate the platform for their business.
