Shopify-Onfleet n8n Automation

Hey, we have created a script in n8n through which whenever an order is placed in Shopify, it is automatically created in Onfleet as well. The issue is that not all orders are coming into Onfleet. I am looking for a developer who can start and fix this up in no time. I will share the script with you. You can add your budget as well. Thank you
