# Evaluate an Individual Decision Request

##

```none
POST {{gatewayInstanceBaseUrl}}/api/authorize
```

The `POST {{gatewayInstanceBaseUrl}}/api/authorize` operation executes a decision request against a gateway instance.

Use `localhost:<port>` for `{{gatewayInstanceBaseUrl}}` in the request URL. The default port is `8080`, but this can be configured when you start a gateway instance. See [Starting an Authorize gateway instance](https://docs.pingidentity.com/pingone/integrations/p1_start_authz_gateway_instance.html) in the PingOne admin documentation for more information.

The request body requires the `parameters` property. The `userContext` property is required if the authorization policies include built-in PingOne User attributes.

This operation uses the opt-in authentication feature. When authentication is enabled and the correct authentication is not provided, a 401 response is returned.

### Prerequisites

* See [Setting up an Authorize gateway](https://docs.pingidentity.com/pingone/integrations/p1_set_up_authz_gateway.html) and [Authentication for Authorize gateway endpoints](https://docs.pingidentity.com/pingone/integrations/p1_authenicate_authz_gateway_endpoints.html) in the PingOne admin documentation for information on deploying Authorize gateways and defining a shared secret for gateway instances.
