Use this interactive demo to learn how to connect your Lovable projects to an external API.

‍

It is very easy to connect Lovable projects to an external API by simply running a prompt. Here’s a quick tutorial on how to do it:

‍

Compose a detailed prompt asking Lovable to connect the project to an external API. For this tutorial, the calculator app will be connected to an external API that fetches currency conversion rates. Type it into the chat box in the left-side panel.
Review the prompt thoroughly. Make sure that it includes all the necessary information regarding the external API, such as URL, Method, Parameters, and Response.
Once done, click the 'Send' button to proceed.
Finally, the external API will be added to your local project based on the provided prompt.

📌 Why this matters

Connecting your projects to external APIs transforms static applications into dynamic, data-driven experiences. Instead of hardcoding values or relying on mock data, you can pull real-time information like currency rates, weather updates, or user profiles directly into your app.

This capability bridges the gap between prototype and production-ready software. When you can seamlessly integrate live data sources, your projects become genuinely useful tools rather than demonstrations, opening doors to building applications that solve real problems with current, actionable information.
