Fulfilling a specific product using a http request via Flow

[KathyRR]

Hello,

I'm trying to fulfil a specific product with the http request in flow.

This is what I currently have that doesn't seem to be working:

Here is the code in the Body:

{
    "query": "mutation fulfillmentCreateV2($fulfillment: FulfillmentV2Input!) {
        fulfillmentCreateV2(fulfillment: $fulfillment) {
            fulfillment { id }
             userErrors { field message }
        }
    }",
    "variables": {
        "fulfillment": {
            "lineItemsByFulfillmentOrder": {
                "fulfillmentOrderId": "{{order.id}}",
                "fulfillmentOrderLineItems": {
                    "id": "gid://shopify/FulfillmentOrderLineItem/6604087001287","quantity": 1
                }
            }
        }
    }
}

This is the error I am getting:

The request was unsuccessful
{"status":400,"response_body":"Bad Request","verb":"POST","url":"https://regalrose.myshopify.com/admin/api/2024-01/graphiql.json","request_body":"{ \"query\": \"mutation fulfillmentCreateV2($fulfillment: FulfillmentV2Input!) {\n    fulfillmentCreateV2(fulfillment: $fulfillment) {\n        fulfillment { id }\n        userErrors { field message }\n    }}\",\n    \"variables\": {\n        \"fulfillment\": {\n            \"lineItemsByFulfillmentOrder\": {\n                \"fulfillmentOrderId\": \"gid://shopify/Order/5635452141767\",\n                \"fulfillmentOrderLineItems\": {\n                    \"id\": \"gid://shopify/FulfillmentOrderLineItem/6604087001287\",\"quantity\": 1\n                }\n            }\n        }\n    }\n}"}

Any help would be appreciated. Thank you.

Your URL is incorrect. It ends in graphql.json not graphiql.json

You may also have to remove white space from your body fields, as newlines can cause the JSON to be invalid. Here's an example that works:

{ "query": "mutation fulfillmentCreateV2($fulfillment: FulfillmentV2Input!) {  fulfillmentCreateV2(fulfillment: $fulfillment) { fulfillment { id } userErrors { field message }  } }", "variables": { "fulfillment": {  "lineItemsByFulfillmentOrder": [{% for fo in order.fulfillmentOrders %}{ "fulfillmentOrderId": "{{fo.id}}"}{% unless forloop.last %}, {% endunless %}{% endfor %}]}}}

Thank you for your help. I copied your code and changed the url and the request went through fine.
