# Onboarding

This channel can be added to a site without any additional configuration. Once added, it will scan every event payload sent to your tag and record payload validation errors in the **Channel Errors** section of the **Analytics** tab in the EdgeTag app.

{% hint style="danger" %}
Add this channel only while debugging issues or making changes to the payloads sent to your tag, and remove it when you're done, as this can increase processing time.
{% endhint %}

### Adding the Channel

The Payload Validator channel will scan every payload for errors and report them while it is installed.

To add the channel, simply specify the channel's name and click **Save & Deploy**. This channel doesn't have any configurable options.

### Reviewing Payload Errors

Once installed, you can click the **Analytics** tab in your site view page to navigate to the tag analytics.

Below, you should see a section called **Channel Errors**. If any errors are detected, they will be presented in this section with the name of the channel you provided. In this example, I used **Validator** as the name of the channel.

Clicking on the **validation** category will display a list of all payload errors and their corresponding payloads.

The error should describe a list of all errors for this payload. You can also inspect the original payload by clicking on the Payload icon, which opens up a full-screen popup containing the payload.

### Removing the Channel

Once you have resolved any payload errors detected, you can remove the channel by opening the channel configuration form and clicking the Delete button.

This will remove the channel and stop scanning incoming event payloads.
