I am at the moment working on a project for an italian store. The shop only ships with GLS.
Sadly I could not find any app which is supported for Italy. The GLS easy App is only available in Germany, Austria and Switzerland.
Does anyone of you know an alternative?
Hi Karambo.
Would MyGLS work for you, even though they focus on Eastern Europe? It could be worth connecting with their team to confirm. Alternatively you could create your own custom app that integrates with Shopify’s Fulfillment API. For this option you would need to work with a developer or have experience working with APIs.
Hi Liam,
sadly this does also not include Italy 
I am bit supprised that it is so restricted by countries!?! Is there any reason for that?
Hi Karambo - I don’t think there’s any specific reason why this app would be restricted to particular countries, but you could check that with the app developer.
