Authentication
You can define two authentication types for the routes in the env file. Authentications must be inserted in the request header.
-
apikey
-
jwt: A JWT is a standard for authentication and information exchange defined with a signature.
Authentications are generated at instance creation time.
Note: There is also the possibility to define a global api key, which can access and control all instances.
