How to set up checkout methods for Lightspeed apps?
By default, your Lightspeed app comes with in-app/native checkout method that allows customers to purchase products from within the app. In case your webstore has additional settings in the checkout process that are incompatible with the mobile app, you can enable web-based checkout to complete the checkout process.
Step 2: From the navigation bar, click Settings > Lightspeed Integration Settings.
Step 3: Scroll down to the Web Checkout setting. By default, this setting is not enabled as your app uses native checkout. To turn on this setting, select the Redirect user to continue checkout using embedded web browser checkbox.
Step 4: Once you've done enabling web checkout, you can decide whether the checkout process uses the in-app browser or default mobile browser. Just scroll down a little and select the browser you want as in the screenshot below.
Step 5: Click Save Changes at the top right of the screen to confirm the change.
