RapidAPI returns 403 error after deploying React Vite app to Netlify

I built a React application using Vite and everything worked great during development. My API calls to RapidAPI were successful when testing locally. However, after deploying to Netlify, I started getting a “slice is not a function” error.

When I checked the network tab, I noticed the RapidAPI requests are returning 403 status codes with a message saying I’m not subscribed to the API. This is strange because the same API key works perfectly in my local environment.

Here’s my API configuration:

export const workoutOptions = {
  method: 'GET',
  headers: {
    'X-RapidAPI-Key': import.meta.env.VITE_RAPID_API_KEY,
    'X-RapidAPI-Host': 'fitness-exercises.p.rapidapi.com'
  }
};

export const videoOptions = {
  method: 'GET',
  headers: {
    'X-RapidAPI-Key': import.meta.env.VITE_RAPID_API_KEY,
    'X-RapidAPI-Host': 'video-search-api.p.rapidapi.com'
  }
};

export const getData = async (endpoint, config) => {
  const res = await fetch(endpoint, config);
  const result = await res.json();
  return result;
}

Has anyone experienced similar issues with RapidAPI and Netlify deployments? The API key is definitely set correctly in my environment variables.

This is a CORS issue mixed with API key problems. RapidAPI handles localhost requests differently than production domains. Check your Netlify environment variables - make sure there’s no extra spaces or characters. I’ve seen builds fail silently because of trailing whitespace in env vars. Also verify if your RapidAPI subscription has domain restrictions. Some plans make you whitelist specific domains, and your Netlify URL might not be authorized. Add error handling to your getData function to log the exact response body when you get a 403. RapidAPI usually gives more detailed error messages than just ‘not subscribed.’

check ur rapidAPI dashboard for domain restrictions on ur subscrpition. free tier often blocks production URLs. also console.log ur env variable in production - make sure its loading cuz netlify can be finicky with env vars.

Had the same issue with my weather app. Your environment variable isn’t getting passed to Netlify’s build process. Check that you’ve added VITE_RAPID_API_KEY in your Netlify site settings under Environment Variables - not just your local .env file. Make sure you rebuild and redeploy after adding it. Also verify your API key’s subscription plan allows cross-origin requests from different domains. Some RapidAPI plans only work with specific domains, and Netlify’s domain might not be whitelisted for your current plan.
