The metadata can then be leveraged by the hosting application and third-party solutions via the Stigg SDKs, API, and webhooks to implement custom functionality, for example, to highlight a selected plan in the paywall. To store metadata on a specific product: 1. In the **Metadata** section of the selected product, click **Add** (if no metadata exists) or **Edit**. 2. Enter the relevant **keys** and **values**. 3. Click **Add** (if there was no previous metadata) or **Save changes** to apply the updates.
