Request Validator: Validate a request path - Plugin

Validate a request path

Configure the plugin to use the draft4 validator to check that the request path contains a status_code parameter with a number value.

Set up the plugin

Add this section to your declarative configuration file:

        required: true
        schema: '{"type": "number"}'
        style: simple
        explode: false

Make the following request:
