Not specifically any experience with xero, but OAuth is a standard protocol.
Depending on what you need to do you can have a look at the open authentication module in the appstore or have a search on the forum for OAuth end rest services. This will help in finding the solution for creating the integration with xero.
Certainly! Integrating with Xero using OAuth2 is a common requirement for many projects. One of the best approaches is to follow Xero's official OAuth2 documentation, which provides detailed instructions and guidelines for implementing the integration securely and efficiently. Additionally, leveraging SDKs or libraries specific to your programming language can simplify the integration process and ensure compliance with OAuth2 standards. Don't hesitate to reach out to Xero's developer community or support resources for further assistance and best practices tailored to your project's needs.
