Defining a Function Authorizer within a Service
Authorizers are defined in the
api.authorizerstable within the service manifest.
auth_type = "iam"
# IAM authorizers take no parameters
To be of any use, an authorizer must be attached to a function (see
authorizer_idin Functions). The type of authorizer must also be supported by the API provider. At this time the default provider (AWS Lambda/APIGW) supports two types of authorization; IAM or JWT.
Authorizers protect only the publicly defined API of a function (such as an HTTP route); a Lambda function can still be invoked by other means (such as the AWS SDK).
auth_type = "JWT"
audience = ["client_id"]
issuer = "issuer_url"
scopes = ["claim1", "claim2", ...] # optional
The JWT type is used for authorizers such as Cognito or Auth0, which support JWT/OAuth authorization.
