Sandbox

A public sandbox is available for testing API connectivity and web trading. While the sandbox only hosts a subset of the production order books, all of the exchange functionality is available. Additionally, in this environment you are allowed to add unlimited fake funds for testing.

Login sessions and API keys are separate from production. Use the sandbox web interface to create keys in the sandbox environment.

To add funds, use the web interface deposit and withdraw buttons as you would on the production web interface.
