      description: "Like many other API providers, it’s also possible to generate API Tokens to be used (in HTTP Header) for authentication. An API token ties to a Admin with equal or less privileges.\n\n**Format**:\n  API Token value format is `Token {apitoken}`\n\n**Notes**:\n* an API token generated for a specific admin has the same privilege as the user\n* an API token will be automatically removed if not used for > 90 days\n* SSO admins cannot generate these API tokens. Refer Org level API tokens which can have privileges of a specific Org/Site for more information."
