Capture Target Org record Id to Source Org - Duplicate scenario

Hello,

I am using Open API 3.0 to connect two Salesforce orgs. I have a scenario where,

Let's say

1. Source Org Account Name : Salesforce, USA
2. Target Org Account Name: Salesforce, USA

There is a duplicate rule in Target Org which doesn't allow us to create the accounts with the same names.

So, when I tried to push the source org record to Target org and I got the error as ( 400 response code)

Result: [{
"message_set" : true,
"message" : "Please choose one of these records instead.",
"errorCode_set" : true,
"errorCode" : "DUPLICATES_DETECTED"
}]

My questions are,

1. Is there anyway to get extract message only from the response?
2. Is there anyway to get the duplicate record Id from the Target org which I can update the Id back to one of the Account's fields in source org?

The response result doesn't return any details apart form the above message so that makes hard for me to refer the target org accountId.

Thank you in advance.
