Cant refund payment with API

[n0oB]

So I have the capture ID.

But when I try to refund the order I get an error.

I have tried with the node.js SDK and also with the web API.

Node.js code:

            const request = new paypal.payments.CapturesRefundRequest(orderId);

            request.requestBody({

                "amount": {

                    "value": "9.37",

                    "currency_code": "EUR"

                }

            });

            const response = await client.execute(request); 

Through Web API:

(

                method: "POST", 

                url: `https://api-m.sandbox.paypal.com/v2/payments/captures/${orderId}/refund`,

                data: {

                    "amount": {

                        "value": "9.37",

                        "currency_code": "EUR"

                    }

                },

                headers: {

                    'Content-Type': 'application/json',

                    'Authorization': 'Bearer ' + token

                }

)

And here my error info (its long so I put some of it):

...

status: 404,
statusText: 'Not Found',

message: 'The specified resource does not exist.',
