+                new IsInRegions(['germany', 'france']),
+                new IsProductInArray(['product-1', 'product-2']),
+                new IsInCurrency('EUR'),
+                new IsValidDiscountCode($discountCode->getCode(), $discountCode->getUsedLimit()),


TBH I'm not sure about the $discountCode->getUsedLimit() part - which value should be passed here, the current usage or the max usage?

If I understand correctly, the condition calls the resolver which takes a single argument - so the second argument to IsValidDiscountCode is actually not used?

Maybe @Steveb-p can clarify, but to me it's the max usage.

+        $discountCode = $this->discountCodeService->createDiscountCode($discountCodeCreateStruct);
+
+        $discountCreateStruct = new DiscountCreateStruct();
+        $discountCreateStruct->setIdentifier('discount_identifier')


I've chosen the fluent API usage over the constructor, as this is self-documenting for the code sample - I'd just use the constructor in "standard" code.

I hope it will be clear for the readers that they can just use the constructor.

@konradoboza thank you for your suggestions, I've applied them in e141ad2

Please note that I've added a small note on Discount Statuses.

I'm lost with expression values and condition Identifiers in REST. Maybe it's only for migration, not REST?
