Plugs

You can use the Guardian Plugs and the ones added by BtrzAuth:

BtrzAuth.Plug.VerifyApiKey

Looks for the header X_API_KEY and verify the account, saving it into conn.private[:application].

BtrzAuth.Plug.VerifyToken

It depends on BtrzAuth.Plug.VerifyApiKey, looks for a token in the Authorization header and verify it using first the account's private key loading the user resource in the conn.private[:user], if not valid, then main and secondary secrets provided by your app for internal token cases. ## Pipelines ### BtrzAuth.Pipeline.ApiKeySecured This pipeline will check the x-api-key header is sent and load the implemented resource inconn.private[:application]. * plug BtrzAuth.Plug.VerifyApiKey ### BtrzAuth.Pipeline.TokenSecured This pipeline will check the x-api-key header loading the application data inconn.private[:application]and also the token with the private key or the configured main and secondary secret keys in case the token could be an internal one, then ensure authenticated and load the implemented resource in theconn.private[:user]. * plug BtrzAuth.Plug.VerifyApiKey * plug BtrzAuth.Plug.VerifyToken * plug Guardian.Plug.EnsureAuthenticated You can add pipelines in your Phoenix Router to get different authentication working. ```elixir pipeline :token_secured do plug BtrzAuth.Pipelines.TokenSecured end scope "/" do pipe_through :token_secured # your routes here... end ``` ## Integration tests in your API Add the test_resource in order to test your endpoints once the plugs or pipelines are defined: ```elixir config :btrz_ex_auth_api, :token, issuer: "your-issuer", main_secret: "YOUR_MAIN_KEY", secondary_secret: "YOUR_SECONDARY_KEY" test_resource: %{account_id: "DESIRED_ID"} ``` and use"test-token"as your test token in theAuthorization` header.
