Where can I view Shiphero provided fulfillment statuses?

Is there a resource where I can see all of the fulfillment statuses offered by Shiphero?

Also, are fulfillment status uniform across all data types, or do orders and purchase orders have different fulfillment statuses?

Hi @jknechtv! Welcome!
Orders and Purchase orders are a little different, but you can also create custom statuses. Please use support@shiphero.com for questions not related to the Public API. Here are some Knowledge Base

articles from help.shiphero.com that may be useful:

Orders, Purchase Orders, and Returns all have the ability to have custom statuses.
