@sai1910 Web APIs are definitely an advanced feature of Thunkable. It’s not as simple as 1, 2, 3. In fact, it may take you a few hours to figure out how to configure the API and test it. If you have a programming background, it may not take you that long.
There’s also often a fee for using APIs.
Start with the link I provided for Google’s Geocoding API. If you get stuck trying to implement it, ask specific questions and people here can help you. There are also many tutorial videos that explain how to use APIs with Thunkable. Just Google thunkable api and you’ll be able to get started.
