Campaigns are time-limited discounts that apply without a code and are shown automatically as a struck-through price.
Go to Marketing → Campaigns and click Create campaign.
Enter a name and optionally a description.
Under Target, choose the target type (e.g. single product) and the product.
Set the discount type and value.
Set the start and end date. Optional: a daily time window (e.g. flash sale 20:00–22:00) and specific weekdays.
Optional: maximum uses and a badge with your own text.
Click Create campaign.
You can also create campaigns for a single course directly in the course editor's Price tab. That is also where you decide whether your course takes part in platform campaigns.
