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
extends:
  - recommended
plugins:
  - './acme-plugin.js'
decorators:
  plugin/change-token-url:
    tokenUrl: 'https://token.example.com/url'
```

```js
import ChangeTokenUrl from './decorators/change-token-url.js';

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

export default function changeTokenPlugin() {
  return {
    id: 'plugin',
    decorators,
  };
}
```

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