--- title: "Test Offer Codes Before Launch" description: "Activate your discount codes ahead of a scheduled campaign so you can verify they work in your store before going live." --- If you want to confirm your discount codes work — and see how they combine with your other offers — before a campaign goes live, you can activate the codes ahead of the launch date. ## Activate Codes Before Launch 1. On the campaign overview screen, find the **Timing** card and click **Edit**. 2. Under **Timing > Starts**, check the box next to **Activate discount codes before campaign launches**. Edit Timing panel with a Specific date start and the 'Activate discount codes before campaign launches' checkbox checked 3. Save the change. Your discount codes are now active in the store, so you can test them before the campaign's start date. This lets you verify that a code's configuration is correct and check how it combines with your other existing offers. :::caution While this box is checked, the codes are genuinely active and valid. If anyone knows a code before the campaign's start date, they can use it. Once your testing is complete, you may want to uncheck **Activate discount codes before campaign launches** until launch. ::: ## Related Tutorials - [Configuring Offers](/shopify/tutorials/offer-configuration) — Set which products each discount applies to - [Managing a Live Campaign](/shopify/tutorials/managing-live-campaign) - [How to Duplicate a Campaign](/shopify/tutorials/duplicate-campaign)
