New Interface (Schnittstelle) programming in Shopware 5

hallo,

I would like to program a new interface in Shopware 5 for interacting with DPD. The goal is to export/send some data from one field e.g. “Delivery address” / “Lieferadresse” in Shopware into a relevant field in DPD portal. (portal.dpd.de)

How I can start with a brand new interface programming? Can I do everything from within the Shopware or I need an extra SDK to implement a brand new Plugin in Shopware?

Thank You for you advices,

In Shopware it’s called a plugin. You may have a look at the Developer Documentation:

Just in case: There’s already a DPD Adapter for Shopware: https://store.shopware.com/viiso73225050566/dpd-adapter-powered-by-pickware.html
