Sending GraphQL mutations and variables on URLConnection

General
1

Hello,

I am trying to send GraphQL mutations and variables on a URLConnection with a Json format but
keep on getting “Bad Request” responses.

An example looks like this:
sQuery = “mutation fulfillmentCreateV2($fulfillment: FulfillmentV2Input!){”
sQuery = sQuery + “fulfillmentCreateV2(fulfillment: $fulfillment){fulfillment{id}userErrors{”
sQuery = sQuery + “field message}}}”

sVars is:
{“variables”:“{“fulfillment”: {“lineItemsByFulfillmentOrder”:[{“fulfillmentOrderId”: “gid://shopify/FulfillmentOrder/nnnn”,“fulfillmentOrderLineItems”: {“id”: “gid://shopify/FulfillmentOrderLineItem/mmmm”,“quantity”: 1}}],“notifyCustomer”: true,“originAddress”: {“address1”: 123 Main Street”“,“address2”: Box 225"”,“city”: Escondido"“,“countryCode”: “USA”,“provinceCode”: Orange”“,“zip”: 95111"”},“trackingInfo”: {“company”: “abc company”,“number”: “2223333”,“numbers”: [“4445555”],“url”: “https://blahblah.com”,“urls”: [“https://blahblah.com”]}},“message”: “Hello world”}"}
myURLConnection.SetRequestContent(sQuery + sVars, “application/json”)
sResult = myURLConnection.SendSync(“POST”, “https://{mystore}.myshopify.com/admin/api/2022-07/graphql.json?access_token=nnnnn”)

I’ve tried omitting “variables” (of course in correct Json format), but no help.

What is being missed here?

Composing your post json with json items then cionverting to string brings more flexibily writtin projects.
Does simple query works?

Query works. Just the mutation and variables not.

did you try replacing strings instead of variables to see it it works to pinpoint the problem ?
do you json first element is name “query” even if it’s mutation ?
