Firstly, you will have to set-up the feature; so you can push your ‘Order data’ onto Logisy via this API:

Please ensure that the ‘Order data’ structure is exactly the same. And as soon as an order is received by your store, you will have to push that Order to Logisy through this API.

Also whenever an order is updated/cancelled in your store, you will have to relay those actions to Logisy using the below APIs:

Order Updated: https://documenter.getpostman.com/view/9962170/TVK5eMvX#f771ad32-f2ba-4a12-9437-12ae10c8aa7e

Order Cancelled: https://documenter.getpostman.com/view/9962170/TVK5eMvX#13b7212c-2471-401a-a393-f1f09aa35e80

Next, whenever you ship your order, you will have to pass on that information to Logisy using the below API: : https://documenter.getpostman.com/view/9962170/TVK5eMvX#0e4a18dd-8763-4fd7-a313-76f384d429e1

Similarly, please implement the feature for ‘Abandoned Checkouts’,as specified in the documentation.

Finally, at your end, the most important APIs are as follows:

Cancel Order API - Logisy will call on this API to cancel an order in your store. https://documenter.getpostman.com/view/9962170/TVK5eMvX#a21e930b-70ec-49a5-ae5f-94190c82df5c

COD to Paid Success API - Logisy will report information to you on this API whenever there is a successful COD to Paid conversion via Logisy. You will then have to either mark the existing COD order as ‘Paid’ or Cancel the COD order and create a new ‘Paid’ order.

Generate Coupon API - Logisy will use this API to generate coupons which will be sent to the users for converting ‘Abandoned Checkouts’. https://documenter.getpostman.com/view/9962170/TVK5eMvX#8f054ef5-c0f2-4404-a0c3-14436bdc239e
