Sandbox environment

Learn about available API environments.

The Tremendous Sandbox environment is a free and fully-featured environment for application development and testing. Nearly all of the Tremendous API is supported in the Sandbox environment.

Tremendous API users typically develop their applications against the Sandbox environment, and then switch their credentials to production when they are ready to go live.

Data is not shared between Sandbox and Production environments.

Using the Sandbox environment


The Sandbox and Production environments use different URLs, and newly issued API keys for each environment are prefixed to help differentiate them.

A full request made to the Sandbox environment with curl would look like this:

curl --url ''\
     --header 'Authorization: Bearer TEST_some-api-key-string'

Redemption experience

Nearly all of a reward recipient’s experience is available in the Sandbox environment.

There are some products where Tremendous redirects a recipient to a partner site, or relies on a partner to email a recipient their reward. These portions of the experience are not available in the Sandbox environment.
