Fulfillment Order not being Auto-generated

Hello - When i create a new order in my Shopify store, it does not appear to be generating a FulfillmentOrder record. Without a FulfillmentOrder record, i cannot push up fulfillments via the API.

Is there a setting or configuration that i need to apply in the product list or storefront for this to work correctly?

Any insights would be helpful. Thanks!

Dont know if this is it but have you set the payment capture to “auto”
