You have two options:

• Download the Revit SDK and open the Revit API Windows help file RevitAPI.chm
• Go to one of the numerous online Revit API documentation websites

Here is an overview of the choices to date that I am aware of:

• apidocs.co – Revit API documentation for 2015, 2016, 2017, 2017.1, 2018, 2018.1, 2018.2, 2019, 2019.1, 2019.2, 2020, 2020.1, 2021, 2021.1, 2022, 2022.1, 2023, 2024, 2025 and 2025.3, plus API documentation for Grasshopper, Navisworks and Rhino
• Rev API Docs – Revit API documentation for 2020, 2021, 2022, 2023, 2024 and 2025, sister website of Civ API Docs, Civil 3D API documentation for 2022, 2023, 2024 and 2025
