# Customizing Integrations

> Modify installed integrations to fit your needs

## What You Can Customize

* OAuth credentials (use your own app)
* RapidForm configuration
* Custom resources
* Environment-specific settings

## Override OAuth Credentials

Use your own OAuth app instead of Handled's default:

<Steps>
  <Step title="Open Settings">
    Go to **Integrations > Installed** and select the integration
  </Step>

  <Step title="Enable Override">
    Click **Settings** and toggle **Use your own OAuth credentials**
  </Step>

  <Step title="Enter Credentials">
    Enter your Client ID, Client Secret, and Scopes
  </Step>

  <Step title="Save">
    Click **Save**
  </Step>
</Steps>

Your customers will see your OAuth app name during authorization.

## Add Custom RapidForm

Collect additional data from users during connection:

1. Navigate to the integration settings
2. Enable RapidForm
3. Configure fields to collect (workspace selection, tag filters, etc.)

See the [RapidForm documentation](/rapid-form/overview) for details.

  <Step title="Edit Integration">
    Go to **Integrations** and click **Edit**
  </Step>

  <Step title="Add Resource">
    Scroll to **Resources** and click **Add Resource**
  </Step>

  <Step title="Configure">
