Sku role in Etsy inventory in case of Printify integration

[stackiflowi]

Hi,

This is not a coding question, rather some clarification required on SKU's.

I've a Printify shop which is integrated with Etsy.

In most of the cases, my Etsy product is created via the Printify publish API method.

I don't fully understand the role of the SKU in the Etsy inventory.

For instance if I deleted accidentally the inventory of my Listing, and I don't want to republish from Etsy, how can I find out what SKU's to use in the inventory? Can it be any random acceptable value which is unique (the the given listing)?

I'm asking because I noticed that Etsy is using SKU's like 12981928198, so a long number, but printify is using SKU's sometimes like 3001_Heather_Dusty_Blue_L sometimes the same as on Etsy.

Whenever an order is created on Etsy, and it's fetched by printify, I assume that SKU's has the key role in the identification of the parameters.
Printify allows not more then 100 variants for a product.
What if I've a product on Etsy with more variants? Where part of the SKU's are coming from Etsy, part of them are random?

Thanks.

So actually I've a similar product (element of inventory) I'd like to build from scratch:

{'product_id': SOME_ID,
'sku': 'SKU',
'is_deleted': False,
'offerings': [{'offering_id': SOME_OTHER_ID,
'quantity': 999,
'is_enabled': True,
'is_deleted': False,
'price': {'amount': 1885, 'divisor': 100, 'currency_code': 'EUR'}}],
'property_values': [{'property_id': 513,
'property_name': 'Colors',
'scale_id': None,
'scale_name': None,
'value_ids': [74650027590],
'values': ['Athletic Heather']},
{'property_id': 514,
'property_name': 'Sizes',
'scale_id': None,
'scale_name': None,
'value_ids': [71931464861],
'values': ['XS']}]}

and I'm interested in how to get or generate the

• sku
  and the
• value_ids

parameters.

value_ids are the same for the same type of color or size, but where they're coming from exactly? I don't find them on Printify.
