Dev environments
View the "Dev environments" page
To begin using one of the APIs available in the developer portal, you need to set up a dev environment for the endpoint. All of the subscription API packages support at least one dev environment (number is dependent on the details of your package), which can be used to isolate usage, rules, rate limits, or otherwise within your systems.
Please note: It is a best practice to associate the products with an app owned by your business @handle to avoid future inconveniences.
