# Conflicting application ID

Discover the solution for conflicting application IDs.

The following error occurs when you specify the Application ID in both the `<script>` tag and the [`plug`](/reference/sdk/javascript/api/plug/plug) method.

> **Error**
>
> The specified app ID and the auto-detected app ID are conflicting. There is no need to specify an app ID when using an application-specific tag. Please try again omitting the `appId` option.

To resolve this issue, either omit the [`appId`](/reference/sdk/javascript/api/plug/plug) option when initializing the SDK or remove the `appId` query parameter from the `src` attribute of the `<script>` tag.
