Integrate 2 API delivery systems in shopify

详细信息

I am looking for someone to integrate 2 API systems on shopify - some orders (the larger ones) will need to be routed to DX api to ship out, and the smaller ones will go to to royal mail (click & drop) for fulfilment with our storage company to pick and pack for Royal mail collection. ***Only apply if you have understanding of shopify API and royal mail integrations.******Must have previous experience of doing of integrating a courier to shopify and show previous experience***Thank you
