API Key Authentication¶
API Key Authentication in Choreo Connect is a simple authentication scheme that accepts a valid self-contained JWT token issued for accessing APIs. Since self-contained tokens can have all authorization information, the token processing time is fast and more efficient. The common practice is to have a short expiration time for self-contained access tokens.
Pick a method below to enable API Key Authentication depending on the Choreo Connect mode you have selected:
Mode | Method |
---|---|
Choreo Connect with WSO2 API Manager as a Control Plane | Secure APIs with API Keys via API-M |
Choreo Connect as a Standalone Gateway | Update the OpenAPI definition of the API |
Update the OpenAPI definition of the API¶
Follow the instructions below to enable API Key Authentication using OpenAPI security schemes.
Info
When you enable API authentication for an API and deploy via WSO2 API Manager, it will override the API Key Authentication defined in the OpenAPI definition. Therefore, the following steps work for Choreo Connect when the API is not deployed via WSO2 API Manager. So use the following steps when you want to enable API Key authentication when deploying an API using the APICTL.
Step 1 - Define the API Key security scheme¶
Security schemes must be defined on the OpenAPI definition under securitySchemes
. One or more API Key security schemes can be used simultaneously, similar to a logical OR operator. Define the API Key security scheme as follows:
Field Name | Description |
---|---|
name |
Header name or query key for the APIKey. |
in |
This can be either header or query . |
type |
Specify apiKey as the type. |
The following example defines an API Key security scheme named apiKeyAuth
, which sends X-API-Key
as a request header. Here, apiKeyAuth
is the name provided for the security scheme and X-API-Key
is the name for the header.
Note
The following example shows how to define API Key security schemes in OAS3. If you are using an OAS2 API definition, go to this Swagger document to get more information on defining API Key security in OAS2.
# step 1 - Define the API Key security scheme
components:
securitySchemes:
ApiKeyAuth: # arbitrary name for the security scheme
type: apiKey
in: header # can be "header" or "query"
name: X-API-KEY # name of the header or query parameter
appId: # you can define several API Key security schemas
type: apiKey
in: header
name: X-APP-ID
Step 2 - Apply the API Key Authentication security scheme¶
A security scheme can be specified at a resource level or to the whole API by using the security
section as applicable. The following is an example of how to apply a security scheme to a resource. A resource-level security scheme will override an API-level security scheme. The ApiKeyAuth
security scheme that has been defined has been referred to from the /pet/{petId}:
resource by using the security section. For more information, refer to the Swagger documentation on API Keys.
- Operation-specific security
The following code snippet is an example of how the API key can be applied to a specific resource.
# step 2 - Specify the API Key security in operation level
"/pet/{petId}":
get:
tags:
- pet
summary: Find pet by ID
description: Returns a single pet
operationId: getPetById
parameters:
- name: petId
in: path
description: ID of pet to return
required: true
schema:
type: integer
format: int64
security:
- ApiKeyAuth: []
-
API Level security
The following code snippet is an example of how the API key can be applied globally to all operations.
# step 2 - Specify the API Key security in api level security: - ApiKeyAuth: []
Step 3 - Generate an API Key¶
Currently, only API Keys issued by WSO2 API Manager are allowed. Hence, you need a valid API Key issued for the particular API Name and the version from WSO2 API Manager. Follow the steps mentioned on generating the API Key documentation to generate an API Key from API Manager.
Step 3 - Invoke the API using the API Key¶
Use one of the following options to invoke APIs using an API key based on the method that you used to define API Key Authentication in step 1.
-
API key defined in the OpenAPI definition security schemes
Execute the following cURL command to invoke APIs when the API key is defined in the OpenAPI definition security schemes.
curl -k -X GET "<API_URL>" -H "accept: application/json" -H "<Header name>: <API Key>"
curl -k -X GET "https://localhost:9095/petstore/v1/pet/1" -H "accept: application/json" -H "X-API-KEY: eyJhbGciOiJSUzI1NiIsICJ0eXAiOiJqd3QiLCAia2lkIjoiYmFsbGVyaW5hIn0=.eyJzdWIiOiJhZG1pbiIsICJpc3MiOiJodHRwczovL2xvY2FsaG9zdDo5MDk1L2FwaWtleSIsICJpYXQiOjE1ODAxMDUzOTAsICJqdGkiOiI3OTFiNzAyMC1kN2U2LTRmYmEtYmMyMy1lMzk5YTVlNmYzYjciLCAiYXVkIjoiaHR0cDovL29yZy53c28yLmFwaW1ndC9nYXRld2F5IiwgImtleXR5cGUiOiJQUk9EVUNUSU9OIiwgImFsbG93ZWRBUElzIjpbXX0=.f-86LfD7lLq-0oM1V1u1dLW7fWcydH4MElWVxUfRTGGRiXHhh8VrS5q18LdCtH1E1jav5pPZpdDQgQUvhVYNXVqiipydfJFOMbDysA0Jdakmh_TVmeZRHhIYgzcVHQNnXMcYXg7Ns4QPBvJVONfbmDluuiU_uFnOPBiXj2N4HL2OTLgVXkEoVTEpL0mmaO2Ab4ZHqKW5xj32aeK8sEAtU5Nd3rQOGvfEwL7xvx4JAmza8ka0eYt7c4QCPVcDSVOkdas9njlsvEdtka5GRL9PAx3xg370phSD1cji6WSRlZhEGzuq6hjLbCqsf17KvZgK1zbrEbSypjgegEe-any3EQ=="

Additional Information¶
API key restriction for IP address and HTTP referrer¶
Choreo Connect API Key Authentication supports API key restriction for IP address and HTTP referrer.
1) IP address restriction¶
The IP address restriction allows only the clients with specific IP addresses to use the token. The IP addresses can be specified in the following formats.
- IPv4 (e.g.,
192.168.1.2
) - IPv6 (e.g.,
2002:eb8::2
) - IP range in CIDR notation (e.g.
152.12.0.0/13
,1001:ab8::/14
)
Generating an API key with an IP restriction
-
Navigate to API key generation window of the specific application in the Developer Portal.
-
Select
IP Addresses
, add the IP addresses in the text input as shown below, and generate the key.
2) HTTP referrer restriction¶
When the HTTP referrer restriction has been enabled, only the specific HTTP referrers can use the token. Therefore, by using this restriction, when API clients run on web browsers, you can limit the access to an API through only specific web pages. The referrer can be specified in the following formats.
- A specific URL with an exact path:
www.example.com/path
- Any URL in a single subdomain, using a wildcard asterisk (*):
sub.example.com/*
- Any subdomain or path URLs in a single domain, using wildcard asterisks (*):
*.example.com/*
Generating an API key with the HTTP referrer restriction
-
Navigate to API key generation window of that specific application in the Developer Portal.
-
Select
HTTP Referrers (Web Sites)
and add the referrers in the text input as shown below and generate the key.
