Connecting Base44 with external APIs lets your app send data, fetch information, trigger automations, and work with tools outside the Base44 platform. This guide walks you through how to connect Base44 with external APIs in 2026, including API keys, endpoints, backend requests, authentication, testing, and common errors.

You’ll learn how to choose the service you want to connect, open its API documentation, create an API key or access token, and decide what data your Base44 app needs to send or receive. We’ll also cover how to configure the API endpoint, choose request methods like GET, POST, PUT, or DELETE, add headers, pass parameters, format JSON, and test the response before using it in your app.

This tutorial is useful if you want to connect Base44 with payment tools, CRMs, email platforms, AI APIs, spreadsheets, booking systems, databases, analytics tools, or automation services. We’ll explain how to protect secret keys, store sensitive credentials in the backend, handle errors, manage rate limits, and make sure your app does not expose private API data to users.

A key part of this Base44 API guide is understanding the difference between frontend actions and backend API calls. Public app screens should not reveal private keys, while backend logic can safely handle authentication and process responses. We’ll also cover common issues like invalid tokens, wrong URLs, CORS errors, missing permissions, failed requests, and data not appearing correctly inside the app.
