The plugin offers automatic as well as manual capture options
If automatic capture is enabled in General Settings, captures will be performed by a cronjob in regular intervals. The frequency of automatic captures can be adjusted in the cronjob settings:
The Riverty module for Shopware makes use of scheduled tasks to capture orders automatically. A 'capture' initiates the invoicing process towards the customer and should start after orders are being shipped. The scheduled task checks if orders are ready to be captured, and if so executes the capture request.
The scheduled task relies on the Shopware system and most probably are already configured on your Shopware environment because other modules make use of this as well. If not, or if you are not sure that this is done, it is best to take a look at the Shopware documentation. It describes how a scheduled task should be configured in your server environment.
If this is all configured, the Riverty module will add an entry to the database table: scheduled_task Identified as: colo_afterpay.capture_payment_task Normally with the status scheduled or queued. If there is an issue with this scheduled task, then the status will be error. And if so, you should look into the var/log directory to see if there are any descriptions of the problem.
