I just found the following reference link and was going through the conversation.
So, I want to know is there any progress on Fulfillment “On-Hold” Status API ?
https://community.shopify.com/c/shopify-apis-and-sdks/order-status-has-not-changed-in-api/m-p/1376029#M74112
As we are currently using this API, but still getting Null response.
Can you help us with that?
