## Managing Promotions

You can edit a promotion at any time after it has been created.

1. Navigate to the **Promotions** list page.
2. Click the **three-dot menu** on the promotion you wish to edit and select the **"Edit"** option from the dropdown. (Alternatively, you can navigate to the promotion's detail page and find an "Edit" option there).

   </Frame>
3. This action takes you back into the promotion editing flow where you update the details.
4. Click **"Update promo"** (or a similar button) to save your changes. Your updates will be reflected live for your users.

## Best Practices

* Always test your promotion setup on a staging environment before going live.
* Use clear, descriptive names for each promotion and discount rule.
* Regularly review and update your discount percentages to match market conditions.
* Use country overrides sparingly and only when necessary.
* Never expose secret identifiers in public code.

***

## Troubleshooting

**Discount not applied?**

* Check your product selection and country rules.
* Ensure the user is eligible for a discount based on your rules.
* For integrated platforms, verify your payment provider connection is active.

**Banner not showing?**

* Ensure your domain is whitelisted in the promotion settings.
* Make sure your API integration uses the correct identifier and parameters.
