Automatic DHL-Shipping-label generation based on Cartonization logic

[MDaveT]

Hi,

I need to find a solution for the following requirements. I would appreciate any help anyone can provide. Thank you!

I would like to implement the following:

1. I have a Shopify shop. When an order comes in, I want the system to automatically recognise how many boxes it needs for the ordered goods. The following number of jars fit into a box (the numbers 1200, 600, 300 stand for the size/weight of the jar, not the quantity):

2x 1200
2x 600
1x 1200 + 1x 600
12x 300
1x 1200 + 6x 300
1x 600 + 6x 300

Alternative: We can also work with the dimensions of the individual product jars and packaging boxes so that the system can use this data to calculate how many jars fit into a box.

2. depending on the number of boxes, a corresponding number of DHL shipping labels should be printed. We have our own DHL business account.

3. the shipping labels should be created automatically after we have received payment (possibly after we have received the order).

4. the shipping labels should be sent automatically via e-mail to our external fulfiller after creation. (Possibly with delivery note)

How can I implement this?
