• Ensure you have bundler installed; if not, run gem install bundler
• Run bundle install from within the sample project root, to install the dependencies

Running the HSA256 Example

Setup the resource server (aka API), and a client

At manage.auth0.com

• Create a new Non-Interactive Client
  • Take note of the following:
    • "Domain" (i.e. yourtenant.auth0.com)
    • "Client ID" (i.e. uF7U8A5xroMfAqTu79CiFPM77oyy49ui)
    • "Client Secret" (i.e. fEsYJVSIKABIAEq18N1qOATCSLZDT4jjG7GyskH5BdMO89x4zdHiphL0W23UJe1K)
• Create a new API using HS256 as the signing algorithm
  • Take note of the following:
    • "Identifier" (specified when you create the API, i.e. https://mygreatapi.example.com)
    • "Signing Secret" (i.e. 2nzFyhR7JNNN5UgH09qYpX4KLj5nKhFP)
• Grant your new client the ability to request access tokens fir your new api by clicking on the "Non Interactive Clients" tab for your API, and toggle "Unauthorized" for your new client to "Authorized"
• Optional If you wish to specify certain scopes to be included in the access token for this client:
  • Create one or more scopes in the "Scopes" tab for your API
  • Under the "Non Interactive Clients" tab for your API, expand the settings for the client (using the arrow to the right of the "Authorized" toggle), and check the scopes you'd like included, and click Save.

Start your server

In your downloaded sample project folder, run:

AUDIENCE=<your API identifier> \
ISSUER=https://<your client domain> \
SIGNING_SECRET=<your API signing secret> \
ruby lib/server_hsa256.rb

Request an access token for your API from Auth0

curl --request POST
  --url https://<your client domain>/oauth/token \
  --header 'content-type: application/json' \
  --data '{"client_id":"<your client id>","client_secret":"<your client secret>","audience":"<your api identifier>","grant_type":"client_credentials"}'

You will receive a JSON response with an access_token value.

Use your access token to gain entry to your API
