All of the settings for the API are managed via Ticket Evolution Settings App including: your API credentials, price markup/markdown rules, price rounding rules, featured inventory and removing brokerage offices from your feed. Other than your default overall markups, these settings can be managed per API token giving you maximum flexibility.
Each environment has it’s own Settings App and the settings are specific to that environment only.
An account for you to login to the Sandbox is not created for you by default. If you need one created please to have one created
