Tennis Bot -> Aktyva - Shipment and Pick Up Bookings

Good day!

Please be advised that we are finalizing our new website and it will be using the Shopify platform. We have already integrated with the shipping API. We would like to understand how the pickups of our shipments will be scheduled.

Please find below our questions.

Is the pickup automatically scheduled as part of booking the shipment via the API?
If yes, what are the terms? (can you specify days, times, etc.)
If not, how does this work?
