We have an online application build in C#.net and Razor which manages and displays loan documents. We'd like to create a web service that returns an XML file of all current loans and the documents associated with that loan. An example of this XML file is attached. This data would be pulled directly from the database which stores all the loan information. Specifics are: 1. External user sends a request to the Web Service. That XML request should contain a unique id and password to ensure that only certain users can retrieve data. If there is a standard/better way to validate requests we can use a different system that you recommend. One other thought we had is to validate based on IP address which may be an easier option. 2. The validation check should be build so that multiple users can be added to the system. This can be a table in the database or some other secure method to validate users. 3. Once the request is validated the Web Service will return an XML response similar to the attached document. This will contain a list of loans from the database with each document associated with the loan and that document's status. I can assist writing the SQL code to grab this list from the database if needed. 4. Integrate the web service into our development site for testing. 5. Provide us with the final code, all source code and instructions for moving this to our production server. Please let me know if you have any questions and I will be happy to answer them.

I do not think IP address is the best option as user may use different machine to handle this. Secret key or Ip is the best option. Before start on it, I want to see the interface and the database. Interface will allow me to understand what is there and how it would call. Database will give me idea what data is there and how I can manage it. Let me know when you can serve me these details?

Hello, I have read through the job details extremely carefully and I am absolutely sure that I can do the project very well. I have pretty good experience in Web services or Web API (since you mentioned you already have application in razor) . So I can create web service which you can host it anywhere or I can create Web API 2 controller within application so that you can consume within application. For authentication, security is must otherwise there is possibility of unnecessary calls or ddos attack etc.. For authorization, I'll implement basic authorization which you can manage by table in database so that add/remove remove anytime. I am having 7+ years of experience in Web Development. I have worked on below technologies/languages/database server. - Asp.net,C#.net, MVC - Linq to SQL,Entity Framework - Jquery,AngularJS,NodeJS - Crystal Reports,DevExpress Reports - SQL server,SSIS Package,SSRS Reports - Web API 2, WCF Rest WebService - Application Security Remediation,Penetration Testing,OWASP 10 - SVN,TFS,Git I love working on SQL and query/sp optimization . I can achieve the results that you are looking for. We can discuss further on chat. Looking forward from your end. Thanks

Hello. Task is basically simple. VS 2015 already have template for building WebAPI applications. Only question is : who will add user? Will this be done by admin in your system or user will be add users by self (so admin panel is needed, like Google API projects). verification can be two-ways combined (again like Google API) key/secret + request origin. (and not only Google, most of APIS use this way). APP on your side can be anything - to access SQL and return XML

Hello, I have some questions: - About the users, are users or other website that comsumes your ws? If users can call your ws directly, ip is not an option for security, if websites, maybe cors its an option.. or tokens. - About Loans, all users have access to all loans? or only to his loans? or some loans? - In the method for call all loans, do you want some pagination? (Imagine call the ws and it returns 3000 loans) -About the xml for return... do you want a xml format that return all loans numbers, user select one loan Id, and the ws returns all directions of that loan... or is better all toghter? (I dont know the size of xmls etc) What framework are you using for your asp.net mvc? and wich version? 3? 4? My idea is use a web api 2. What do you think? Regards -

I have been working with web services (SOAP and rest) for the past 3 years now. My current project is an international shipping system for Royal Mail which is current in production.. It required us to create out own API so that clients can create shipments and return back an xml of that shipment. You requirement sounds very easy, and would be better with a REST API rather than a Soap Service.
