# OAuth 2.0/JWT authorizer example for AWS SAM
<a name="serverless-controlling-access-to-apis-oauth2-authorizer"></a>

You can control access to your APIs using JWTs as part of [OpenID Connect (OIDC)](https://openid.net/specs/openid-connect-core-1_0.html) and [OAuth 2.0](https://oauth.net/2/) frameworks. To do this, you use the [HttpApiAuth](sam-property-httpapi-httpapiauth.md) data type.

The following is an example AWS SAM template section for an OAuth 2.0/JWT authorizer:

```
Resources:
  MyApi:
    Type: AWS::Serverless::HttpApi
    Properties:
      Auth:
        Authorizers:
          MyOauth2Authorizer:
            AuthorizationScopes:
              - scope
            IdentitySource: $request.header.Authorization
            JwtConfiguration:
              audience:
                - audience1
                - audience2
              issuer: "https://www.example.com/v1/connect/oidc"
        DefaultAuthorizer: MyOauth2Authorizer
      StageName: Prod
  MyFunction:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: ./src
      Events:
        GetRoot:
          Properties:
            ApiId: MyApi
            Method: get
            Path: /
            PayloadFormatVersion: "2.0"
          Type: HttpApi
      Handler: index.handler
      Runtime: nodejs12.x
```
