I’m working on a React Native application and facing some challenges with the API integration. Initially, I was retrieving user data directly from my server using a straightforward fetch request, like this:
async loadUserData() {
try {
const result = await fetch('myserver.com/userinfo.json');
const jsonData = await result.json();
this.setState({
loading: false,
userData: jsonData,
});
}
catch (err) {
console.log(err);
}
}
Now, I want to adopt RapidAPI for enhanced security, but it results in a blank screen:
async loadUserData() {
try {
const result = await fetch('dice-roll-api.p.rapidapi.com/roll', {
"method": "GET",
"headers": {
"x-rapidapi-host": "myserver.com",
"x-rapidapi-key": 'abc123def456ghi789jkl012mno345pqr678stu901vwx234yz'
}
});
const jsonData = await result.json();
this.setState({
loading: false,
userData: jsonData,
});
}
catch (err) {
console.log(err);
}
}
The official documentation for RapidAPI provides this example:
const getData = () => {
beginRoll();
setIsLoading(true);
fetch('https://dice-roll-api.p.rapidapi.com/roll', {
"method": "GET",
"headers": {
"x-rapidapi-host": "dice-roll-api.p.rapidapi.com",
"x-rapidapi-key": 'your_api_key'
}
})
.then((result) => result.json())
.then((data) => setResult(data.value))
.catch(() => Alert.alert('Error occurred', 'Failed to get dice roll result'))
.finally(() => {
setIsLoading(false);
endRoll();
});
};
Can someone help me understand what might be incorrect in my RapidAPI implementation?
Your headers are mixed up. You’ve got the dice roll API endpoint but you’re using your own server host:
"x-rapidapi-host": "myserver.com"
The host header needs to match whatever endpoint you’re calling. If you want to call your own API through RapidAPI, use your actual RapidAPI endpoint, not the dice roll example.
Also make sure you’re using https:// in your URL.
Honestly, hardcoding API integrations like this gets messy fast. Error handling, retries, rate limiting - it all piles up. I’ve switched to automating these workflows instead.
With automation, you set up flows that handle API calls, transform data, add caching, even fallback to different endpoints when one fails. Your React Native app just hits your automation endpoint instead of dealing with all this complexity.
I’ve built setups where the mobile app stays clean and simple while automated workflows do the heavy lifting. Way easier to maintain and debug.
Check out Latenode for this kind of API automation: https://latenode.com
you’re calling the dice roll API but your host is set to myserver.com - that’ll mess up RapidAPI’s routing. also looks like you’re missing https:// in the URL. check your network response first - you might be getting 401 or 403 errors causing the blank screen.
Your problem is mixing the dice roll API URL with your own server’s host header. The x-rapidapi-host header needs to match the actual API endpoint you’re calling. Since you’re hitting dice-roll-api.p.rapidapi.com/roll, your host header should be dice-roll-api.p.rapidapi.com, not myserver.com. If you want to call your own API through RapidAPI, use the right RapidAPI endpoint and make sure your API key has access. Also check that your API is published on RapidAPI marketplace and you’re on the right subscription tier - blank screens often come from permission issues or CORS problems in React Native.
You’ve got a configuration mismatch. You’re hitting the dice roll API endpoint but setting the host header to your own server - that confuses the RapidAPI proxy and it doesn’t know where to route your request. I hit this same problem when I switched from direct API calls to RapidAPI. You need to pick one: either call an existing RapidAPI service or host your own API through their platform. Looking at your code, it seems like you want to access your userinfo.json through RapidAPI. You’ll need to either publish your API on their marketplace or use their private hosting first. Then use the actual RapidAPI endpoint URL they give you - not that dice roll example. Make sure your host header matches the real endpoint domain. Add some logging to see what response you’re getting before that blank screen shows up. Check your network tab in the debugger to see the actual HTTP status and response body.
