All responses have a wildcard same-origin header which makes the API completely accessible. ### Authentication SIMULATOR OPENAPI offers following forms of authentication: - Bearer Token (JWT) - API Key ### Error Handling This API uses HTTP status codes equal or above 400 to indicate errors. Error details are generated in compliance with [RFC 7807 - "Problem Details for HTTP APIs"](https://tools.ietf.org/html/rfc7807). Every error response contains a traceId, which should be provided to the SIMULATOR OPENAPI Technical Support when reporting an error. contact: name: Cognigy Technical Support url: https://www.cognigy.com email: support@cognigy.com license: name: Cognigy Proprietary License servers: -
