Estimated time: 15 minutes


## Step-by-step instructions

1. Add this code to your repo with the API (the Redocly configuration file is an example).
    ```yaml redocly.yaml
    extends:
      - recommended
    plugins:
      - './acme-plugin.js'
    decorators:
      plugin/change-token-url:
        tokenUrl: "https://token.example.com/url"
    ```

    ```js acme-plugin.js
    const ChangeTokenUrl = require('./decorators/change-token-url');
    const id = 'plugin';

    /** @type {import('@redocly/cli').CustomRulesConfig} */
    const decorators = {
      oas3: {
        'change-token-url': ChangeTokenUrl,
      },
    };

    module.exports = {
      id,
      decorators,
    };
    ```

    ```js decorators/change-token-url.js
    module.exports = ChangeTokenUrl;

    /** @type {import('@redocly/cli').OasDecorator} */
    function ChangeTokenUrl({tokenUrl}) {
      return {
        OAuth2Flows: {
          leave(flows, ctx) {
            if (tokenUrl) {
              flows.clientCredentials.tokenUrl = tokenUrl;
            }
          }
        }
      }
    };
    ```
