Authentication
The Authenticator defines how to configure outgoing HTTP requests to authenticate on the API source.
Schema:
Authenticator:
type: object
description: "Authenticator type"
anyOf:
- "$ref": "#/definitions/OAuth"
- "$ref": "#/definitions/ApiKeyAuthenticator"
- "$ref": "#/definitions/BearerAuthenticator"
- "$ref": "#/definitions/BasicHttpAuthenticator"
Authenticators
ApiKeyAuthenticator
The ApiKeyAuthenticator sets an HTTP header on outgoing requests.
The following definition will set the header "Authorization" with a value "Bearer hello":
Schema:
ApiKeyAuthenticator:
type: object
additionalProperties: true
required:
- header
- api_token
properties:
"$parameters":
"$ref": "#/definitions/$parameters"
header:
type: string
api_token:
type: string
Example:
authenticator:
type: "ApiKeyAuthenticator"
header: "Authorization"
api_token: "Bearer hello"
BearerAuthenticator
The BearerAuthenticator is a specialized ApiKeyAuthenticator that always sets the header "Authorization" with the value Bearer {token}.
The following definition will set the header "Authorization" with a value "Bearer hello"
Schema:
BearerAuthenticator:
type: object
additionalProperties: true
required:
- api_token
properties:
"$parameters":
"$ref": "#/definitions/$parameters"
api_token:
type: string
Example:
authenticator:
type: "BearerAuthenticator"
api_token: "hello"
More information on bearer authentication can be found here.
BasicHttpAuthenticator
The BasicHttpAuthenticator set the "Authorization" header with a (USER ID/password) pair, encoded using base64 as per RFC 7617.
The following definition will set the header "Authorization" with a value Basic {encoded credentials}
Schema:
BasicHttpAuthenticator:
type: object
additionalProperties: true
required:
- username
properties:
"$parameters":
"$ref": "#/definitions/$parameters"
username:
type: string
password:
type: string
Example:
authenticator:
type: "BasicHttpAuthenticator"
username: "hello"
password: "world"
The password is optional. Authenticating with APIs using Basic HTTP and a single API key can be done as:
Example:
authenticator:
type: "BasicHttpAuthenticator"
username: "hello"
OAuth
OAuth authentication is supported through the OAuthAuthenticator, which requires the following parameters:
- token_refresh_endpoint: The endpoint to refresh the access token
- client_id: The client id
- client_secret: The client secret
- refresh_token: The token used to refresh the access token
- scopes (Optional): The scopes to request. Default: Empty list
- token_expiry_date (Optional): The access token expiration date formatted as RFC-3339 ("%Y-%m-%dT%H:%M:%S.%f%z")
- access_token_name (Optional): The field to extract access token from in the response. Default: "access_token".
- expires_in_name (Optional): The field to extract expires_in from in the response. Default: "expires_in"
- refresh_request_body (Optional): The request body to send in the refresh request. Default: None
- grant_type (Optional): The parameter specified grant_type to request access_token. Default: "refresh_token"
