Organizations are a way to separate different parts of your business within the same Tremendous account.
You can assign users in your Tremendous team as members to any organization. Users can be members of multiple organizations at once.
API keys belong to a single organization. The API key used in a request determines on behalf of which organization the request is carried out.
Important note: When creating an organization, you are required to either pass with_api_key or copy_settings[user] in the request body as true. This ensures that your new Organization can either be accessed via the API or the Dashboard.
