2. Go to Settings > Payments. Configure the following settings:

   Property	Description/Actions
   Add payment methods	When installing the plugin, all payment methods the plugin supports and that are active in your account are made available automatically.
   Payment capture	Define whether to process the transactions as authorisation mode or as direct sale by clicking on the "Payment capture" button. Select one of the following options: "Automatically capture payment for orders": The amount has been ordered to be paid out in one go. Use this mode to receive the money before shipping the order There are no further actions required to capture the transaction. Successful transactions will have status="CAPTURED" / statusOutput.statusCategory="COMPLETED" / statusOutput.statusCode=9 In the Shopify Back office, the status will be "Paid". "Manually capture payment for orders": The amount is only blocked on your customer's card. Successful transactions will have status="PENDING_CAPTURE" / statusOutput.statusCategory="PENDING_MERCHANT" / statusOutput.statusCode=5 (Use this mode when you wish to capture a transaction only after shipping the order). In the Shopify Back office, the status will be "Authorized". Click on "Save" to confirm your settings. If "Payment capture" is set to "Manually capture payment for orders", beware of the following: Make sure that you capture authorised transaction later.

Capture transaction in the Shopify Back Office via the Order module.
