Fulfillment Service PUT request issue.

[VladimirZa]

Hello. I'm Shopify app developer. Could you help me with Fulfillment Services update, please? We use shopify_api Rails gem. We need to update callback_url in Fulfillment Services (we're rebalancing our servers' load). When we use shopify_api gem and make request e.g. ShopifyAPI::FulfillmentService.find(:all) or ShopifyAPI::FulfillmentService.all we have empty array response (maybe this is a gem issue). When we use shopify_api with GET request we receive FulfillmentServices list. But when we send PUT request we receive error message "Fulfillment service could not be found". We use this store for tests: joke-shop-come-back.myshopify.com.

Hey @VladimirZa, 

While our team are unable to provide authenticated support or locate store related info from these forums at this time, we are always here help or make a few suggestions.

In this case, the error you are getting is often returned when trying to request or modify a list created by another fulfillment service, and would recommend taking the time to confirm that the fulfillment list you are trying to updated was created by your app.

If you need someone to take a closer look, you are welcome to contact the Partner Support team from the Partner Dashboard > Support menu. While not a technical developer team, they can absolutely work through steps for authentication and take a closer look. If you feel the issue is beyond your app and instead related to a technical issue with a client's store, I would suggest having them reach out to our Support Advisor team directly from this link as a first step. 

- Cheers!
