### Domain verification

In order to use Google API Webhooks you have to verify your domain ownership. More about domain verification can be found in [here](https://support.google.com/a/topic/9196?hl=en\&ref_topic=3540977). When Appmixer is running on your servers, you can use [CNAME](https://support.google.com/a/answer/47283?hl=en\&ref_topic=29598) records to verify your domain ownership, but if you want to use components that use Google API Webhooks (*appmixer.google.drive.NewFile for example*) in an Appmixer instance running on your localhost (typical for testing the *trial* or when developing new components) you need something else. When running Appmixer on localhost, you usually use tools like [*ngrok*](https://docs.appmixer.com/6.0/v4.1/appmixer-self-managed/installation#using-webhook-components) to create public tunnel to the Appmixer API. In order to verify *ngrok* domain ownership you can use the [*HTML file method*](https://support.google.com/a/answer/63026?hl=en) .

First, open Google developers console and your Appmixer project and follow instructions in the next picture.

Then copy\&paste your *ngrok* URL.

Then you have to verify domain ownership.

Click 'Take me there' and then 'Add a property'.

Then download the HTML verification file.

![Download HTML verification file](https://198492512-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LATDgYqVMe0hChW7efU%2F-MN8XGAFTgjdoDk0K75Z%2F-MN9WBwJVsJYsdUqKQdo%2FWebmaster_Central.png?alt=media\&token=2886fedf-024e-402a-ac01-160e401f1694)

After you download your HTML verification file, copy it into Appmixer engine.

```
docker cp google52658022a92d779c.html appmixer-401_engine_1:/usr/src/appmixer/gridd/public
```

After then, click the 'Verify' button and that's it. You don't need to restart the Appmixer engine.

Now, you can go back to developer console and add the *ngrok* domain once more.

But this time, because it's already verified, it will appear in the list of your domains.
