docs	Bearer	Bearer	Use bearer middleware to secure HTTP endpoints by verifying bearer tokens	docs	/developing-applications/middleware/supported-middleware/middleware-bearer/

The bearer [HTTP middleware]({{< ref middleware.md >}}) verifies a Bearer Token using OpenID Connect on a Web API, without modifying the application. This design separates authentication/authorization concerns from the application, so that application operators can adopt and configure authentication/authorization providers without impacting the application code.

Component format

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: bearer-token
spec:
  type: middleware.http.bearer
  version: v1
  metadata:
    - name: audience
      value: "<your token audience; e.g. the application's client ID>"
    - name: issuer
      value: "<your token issuer, e.g. 'https://accounts.google.com'>"

    # Optional values
    - name: jwksURL
      value: "https://accounts.google.com/.well-known/openid-configuration"

Spec metadata fields

Field	Required	Details	Example
audience	Y	The audience expected in the tokens. Usually, this corresponds to the client ID of your application that is created as part of a credential hosted by a OpenID Connect platform.
issuer	Y	The issuer authority, which is the value expected in the issuer claim in the tokens.	"https://accounts.google.com", "https://login.salesforce.com"
jwksURL	N	Address of the JWKS (JWK Set containing the public keys for verifying tokens). If empty, will try to fetch the URL set in the OpenID Configuration document <issuer>/.well-known/openid-configuration.	"https://accounts.google.com/.well-known/openid-configuration"

Dapr configuration

To be applied, the middleware must be referenced in [configuration]({{< ref configuration-concept.md >}}). See [middleware pipelines]({{< ref "middleware.md">}}).

apiVersion: dapr.io/v1alpha1
kind: Configuration
metadata:
  name: appconfig
spec:
  httpPipeline:
    handlers:
    - name: bearer-token
      type: middleware.http.bearer
