Assuming that the broker is already logged into your website, you can do this by passing his login and password (assuming that it’s the same) to the AuthService to get a PmlUserAuthTicket. Then pass this ticket to the AppView to get back a URL that can be used for redirection.

            string userName = "lo_user";
            string password = "password";
            
            AuthService authService = new AuthService();
            string sTicket = authService.GetUserAuthTicket(userName, password);
            
            AppView appView = new AppView();
            string sUrl = appView.GetViewDesktopUrl(sTicket); 
            // Redirect user to "https://secure.mortgage.meridianlink.com/" + sUrl.
            

            string userName = "lo_user";
            string password = "password";
            string customerCode = "pmlxxxx";
            
            AuthService authService = new AuthService();
            string sTicket = authService.GetPmlUserAuthTicket(userName, password, customerCode);
            
            AppView appView = new AppView();
            string sLoanName = "xxxxx";            
            string sUrl = appView.GetPmlLoanUrl(sTicket, sLoanName); 
            // Redirect user to "https://origination.mortgage.meridianlink.com/" + sUrl.
            

If your back-end system was developed by a third-party LOS vendor, then we strongly suggests that you ask that vendor to build the integration for you. It should cost less since that LOS vendor can then spread the implementation costs across multiple customers.

First, make sure you understand how to use web-services. There are many resources on the web discussing this. If you are using Microsoft Visual Studio.NET, you will find that Microsoft has done a wonderful job in providing tools to automatically create proxy classes to handle the communications. Second, implement the integration in stages. Here are the proposed stages and functionality associated with them.
Stage 1
Modify your system to allow the user to import/export loan data by entering a LO/PML loan # and clicking on a single button. Data transfer at this point will be manually driven by the user. The data that should be transferred are loan data and underwriting conditions.
Stage 2
Automate data transfer by using our Modified Loans tracking mechanism. You will need to ask us to turn this on for your account. Once it’s activated, we will track loans that are modified in our system. Your system can then poll our system for a list of loans that were modified on a fixed interval. We will identify to you the loans that were modified so that your system can automatically import them in. This will eliminate the need for the user to manually hit a button to do the data import. The user will still need the ability to manually export a loan file if your system does not have a mechanism to automatically export modified loan files to our system. The methods that you would use here is the ListModifiedLoans and ClearModifiedLoanByName. REMINDER: You will need to ask us to turn on this tracking feature in order for the ListModifiedLoans method to return anything.

To retrieve list of conditions.

            string userName = "lo_user";
            string password = "password";
            
            AuthService authService = new AuthService();
            string sTicket = authService.GetUserAuthTicket(userName, password);
            
            Loan loanService = new Loan();
            
            string sLNm = "xxxxx";
            string sXmlQuery = GenerateConditionRequest(); // Should return content of SampleConditionsRequest.xml
            
            string ret = loanService.Load(sTicket, sLNm, sXmlQuery, 0); // Example return string SampleConditions.xml
            

To add or modify conditions. Condition is identify by the description. If the condition text does not exists in the system then new condition will get create.

            string userName = "lo_user";
            string password = "password";
            
            AuthService authService = new AuthService();
            string sTicket = authService.GetUserAuthTicket(userName, password);
            
            Loan loanService = new Loan();
            
            string sLNm = "xxxxx";
            string sDataContent = GenerateConditions(); // Should return content of SampleConditions.xml
            
            string ret = loanService.Save(sTicket, sLNm, sDataContent, 0); 
            

You will need to invoke a Save method and pass over a list of field ids relate to PriceMyLoan. To see the complete list of ids look at SamplePriceMyLoanSave.xml. You do not require to pass over a complete list. We only update values that are include in the xml you send to us.

            string userName = "lo_user";
            string password = "password";
            string customerCode = "pmlxxxx";
            
            AuthService authService = new AuthService();
            string sTicket = authService.GetPmlUserAuthTicket(userName, password, customerCode);
            
            Loan loanService = new Loan();
            
            string sLNm = "xxxxx";
            string sDataContent = GenerateData(); // Should return content of SamplePriceMyLoanSave.xml. Do not include comment.
            
            string ret = loanService.Save(sTicket, sLNm, sDataContent, 0); 
            

Use the Load method and pass over an id for Pml Certificate (sPmlCertHtml).

            string userName = "lo_user";
            string password = "password";
            string customerCode = "pmlxxxx";
            
            AuthService authService = new AuthService();
            string sTicket = authService.GetPmlUserAuthTicket(userName, password, customerCode);
            
            Loan loanService = new Loan();
            
            string sLNm = "xxxxx";
            string sXmlQuery = GenerateRequest(); // Should return content of SampleGetPmlCert.xml.
            
            string html = loanService.Load(sTicket, sLNm, sXmlQuery, 0); 
            // Display html result in separate browser.
            

Use the Load method and pass over an id for Pml Pricing Result (PricingResult).

            string userName = "lo_user";
            string password = "password";
            string customerCode = "pmlxxxx";
            
            AuthService authService = new AuthService();
            string sTicket = authService.GetPmlUserAuthTicket(userName, password, customerCode);
            
            Loan loanService = new Loan();
            
            string sLNm = "xxxxx"; // The loan file must existed with all required information set in MeridianLink Mortgage. You can use the Save() method to initialize the data.
            string sXmlQuery = GenerateRequest(); // Should return content of SampleGetPricingResult.xml.
            
            string result = loanService.Load(sTicket, sLNm, sXmlQuery, 0); // The result will look like SamplePricingResult.xml
            
            // To process the pricing result you will need to retrieve InnerText of //LOXmlFormat/loan/field[@id='PricingResult'] and create an XmlDocument out of it.
            

            string userName = "lo_user";
            string password = "password";
            string customerCode = "pmlxxxx";
            
            AuthService authService = new AuthService();
            string sTicket = authService.GetPmlUserAuthTicket(userName, password, customerCode);
            
            Loan loanService = new Loan();

            // For full spec of sXmlData read LOQuickPricerFormat.xsd.            
            string sXmlData = @"<loan sHouseValPe=""350000"" sLAmtCalcPe=""280000"" sLPurposeTPe=""1"" sProdFilterTerm30Yrs=""true"" sProdFilterTerm15Yrs=""true"" sProdFilterTerm20Yrs=""true"" sProdFilterTermOther=""true"" sProdFilterFinMeth3YrsArm=""true"" sProdFilterFinMeth5YrsArm=""true"" sProdFilterFinMeth7YrsArm=""true"" sProdFilterFinMeth10YrsArm=""true"" sProdFilterFinMethFixed=""true"" sProdIncludeNormalProc=""true"" sCreditScoreType1=""740"" sSpStatePe=""CA"" sSpCounty=""Los Angeles"" sProdRLckdDays=""30"" sSpZip=""90024"" sOccTPe=""0"" sProdSpT=""0"" sProdImpound=""false""sProdIncludeMyCommunityProc=""false"" sProdIncludeHomePossibleProc=""false"" sProdIsDuRefiPlus=""false"" sProdIncludeFHATotalProc=""true""  sProdIncludeVAProc=""true"" />";
            
            string result = loanService.RunQuickPricer(sTicket, sXmlData); // The result will look like SampleQuickPricerResult.xml
            

Use the Save method and pass over the <credit> element.

            string userName = "lo_user";
            string password = "password";
            string customerCode = "pmlxxxx";
            
            AuthService authService = new AuthService();
            string sTicket = authService.GetPmlUserAuthTicket(userName, password, customerCode);
            
            Loan loanService = new Loan();

            string sLNm = "xxxxx";
            string sXmlData = GenerateSaveDataRequest();// GenerateSaveDataRequest should return xml similar to SampleOrderNewCredit.xml 
            
            string ret = loanService.Save(sTicket, sLNm, sXmlData, 0);

To retrieve a raw credit report from our system use aCreditReportRawXml field id.

            Loan loanService = new Loan();

            string sLNm = "xxxxx";
            string sXmlData = @"<LOXmlFormat version=""1.0""><loan><applicant><field id=""aCreditReportRawXml"" /></applicant></loan></LOXmlFormat>";
            
            string ret = loanService.Load(sTicket, sLNm, sXmlData, 0);
          
          

In order to submit to FHA TotalScorecard you need to have 1003 complete fill out and a credit report.

            string userName = "lo_user";
            string password = "password";
            string customerCode = "pmlxxxx";
            
            AuthService authService = new AuthService();
            string sTicket = authService.GetPmlUserAuthTicket(userName, password, customerCode);
            
            Loan loanService = new Loan();
            string fannieMaeContent= LoadFannieMaeContentFromFile(fileName);//Load your fnma content here

            string sLNm = loanService.CreateWithFannieMaeFile(sTicket, fannieMaeContent);
            
            // Invoke API to either reissue or reissue credit report in our system.
            string sXmlData = GenerateSaveDataRequest();// GenerateSaveDataRequest should return xml similar to SampleOrderNewCredit.xml 
            
            string ret = loanService.Save(sTicket, sLNm, sXmlData, 0);
            
            // Submit to TotalScorecard
            string responseXml = loanService.SubmitTotalScorecard(sTicket, sLNm);
            
            // Parse responseXml. If status is OK then retrieve TotalScore certificate. Otherwise display error
            string sXmlRequestCertificate=@"<LOXmlFormat version=""1.0""><loan><field id=""sTotalScoreCertificateHtml"" /></loan></LOXmlFormat>";
            string certRet = loanService.Load(sTicket, sLNm, sXmlData, 0);
