I am trying to make a refund to the payment using API
tried this https://docs.connect.squareup.com/api/connect/v1#post-refunds
here is the request that I used
{"payment_id":"XXXXXXXXXXXXXXXXX","type":"FULL","reason":"Items not available","refunded_money":{"amount":-100,"currency_code":"USD"},"request_idempotence_key":null}
I am getting a response
{"type":"unauthorized","message":"Provided merchant_id and merchant_id in authorization do not match up"}
In the documentation not mentioned about merchant_id, but response shows error regarding merchant_id.
