Use the response to Download the PDF of the transaction. Either we can write some javascript to download the blob content or use the Salesforce Attachment object or a combination of both.
Sample Usage of the response:
Apex
// After making the Breadwinner callout
Map<String, Object> respMap = BreadwinnerXeroAPI.call(reqObj);

if(respMap.get('apiErrors')!=null){
    system.debug(respMap.get('apiErrors'));
    //write your custom code here
    // Breadwinner errors thrown before making a request to Xero. i.e action name incorrect
}
else{ // request successfully sent to Xero
    PdfResponse res =(PdfResponse)JSON.deserialize(String.valueOf(respMap.get('responseJSON')),PdfResponse.class);
    
    if(res.statusCode!=NULL && res.statusCode==200){ // Xero returned PDF response
        Attachment att = new Attachment();
        att.Body = res.pdfResponse;
        att.ParentId = '0010p00001Au4vuAAB'; // Salesforce record Id
        att.contenttype = 'application/pdf';
        att.Name = 'Invoice-pdf-01';
        system.debug(att);
        Insert att;
    }
    else{
        system.debug(res.errors); // Xero returned errors
    }
}

public class PdfResponse{
    public Blob pdfResponse;
    public Integer statusCode;
    public String type;
    public String referenceId;
    public List<ErrorClass> errors;
}

public class ErrorClass{
    public String message;
    public String code;
}

// After making the Breadwinner callout
Map<String, Object> respMap = BreadwinnerXeroAPI.call(reqObj);

if(respMap.get('apiErrors')!=null){
    system.debug(respMap.get('apiErrors'));
    //write your custom code here
    // Breadwinner errors thrown before making a request to Xero. i.e action name incorrect

else{ // request successfully sent to Xero
    PdfResponse res =(PdfResponse)JSON.deserialize(String.valueOf(respMap.get('responseJSON')),PdfResponse.class);
    
    if(res.statusCode!=NULL && res.statusCode==200){ // Xero returned PDF response
        Attachment att = new Attachment();
        att.Body = res.pdfResponse;
        att.ParentId = '0010p00001Au4vuAAB'; // Salesforce record Id
        att.contenttype = 'application/pdf';
        att.Name = 'Invoice-pdf-01';

        Insert att;
    }
    else{
        system.debug(res.errors); // Xero returned errors
    }
}

public class PdfResponse{
    public Blob pdfResponse;
    public Integer statusCode;
    public String type;
    public String referenceId;
    public List<ErrorClass> errors;
}

public class ErrorClass{
    public String message;
    public String code;
}

In the above code sample, we are using the Attachment object (attach the PDF to any Salesforce record).
You can even use the Document object in place of the Attachment object.
Field Name	Data Type	Description
referenceId	string	Internal Id of the Transaction
