You will get Xero API Integration with .NET - Accounting & Payroll (AU, UK, NZ)
Top Rated
Project details
This project is a complete, working integration across both Accounting AND Payroll (AU, UK, NZ), including pay codes, employees, and timesheets pushed directly into Xero Payroll.
It's not a template or a proof-of-concept — it's a fully functional .NET application with real OAuth2 authentication, tested against a live Xero organisation (Demo Company) , with data syncing in both directions (Xero to SQL Server, and App To Xero).
You're not just getting an integration built for you — you're getting the complete source code and database design behind it, which you can use as your full solution, adapt to your existing project, or extend with custom development. That means less time spent on Xero's API quirks and OAuth setup, and more time on the extra feature development.

I highly recommend Mahesh Thakkar for any programming-related position within your organization. I have worked closely with Mahesh at codeWorthy for the past 7 years (6 September 2016 to 1 October 2023) and I can attest to his exceptional skills, dedication, and outstanding contributions to our team.
It has been a pleasure working with Mahesh, but unfortunately due to the sale of our business, Mahesh is no longer employed by codeWorthy Pty Ltd.
I have managed programmers for over 25 years, and I can honestly say the Mahesh is the best I have ever come across. Mahesh is a highly talented and diligent programmer who consistently demonstrates expertise in numerous technologies: .Net Core, Asp.Net MVC, Asp.Net Web Forms, Web API, Web Services, C#, VB, Typescript, Javascript, JavaScript, TypeScript, KnockoutJS, jQuery, jQueryUI, RequireJS, Google Maps APIs, HTML5, Bootstrap-3/4, LESS, SCSS, CSS, Xamarin, Xamarin Forms, MS-SQL Server, Entity Framework, LINQ , Dapper, ADO.Net, SSRS, EWS, SharePoint and Xero API integration using OAuth 2.0 and MessageNet API (and I’m sure that I have missed some here).
Mahesh’s ability to tackle complex problems and deliver robust solutions has been an asset to our projects. He consistently produces high-quality, clean and maintainable code.
In addition to Mahesh's technical skills, he has excellent communication skills. Mahesh has fluent English (both verbal and written), and he has an excellent attitude to communication (polite, direct, emphasis on logic, assertive when required, and tolerant to disagreement). He communicates very well with clients and end users and is able to translate users’ requests into actionable programming tasks.
In summary, Mahesh is an exceptional programmer who consistently goes above and beyond in every task he undertakes. His dedication, technical proficiency, and collaborative spirit make him a standout team member, and I have no doubt that he will excel in any programming role. I wholeheartedly recommend Mahesh for any position that requires a skilled and dedicated programmer.
