Trouble fetching data from RapidAPI in Flutter application

I’m having issues getting data into my Flutter app. When I use the JSONPlaceholder API, everything works fine, but switching to RapidAPI doesn’t load any data.

I’m not sure if this is due to the server connection or another reason. Here’s a reworked version of my code that might help clarify the issue:

import 'package:flutter/material.dart';
import 'package:http/http.dart' as http;
import 'dart:convert';

Future<List<Recipe>> getRecipes() async {
  final url = Uri.https('cookbookapi.example.com', '/recipes/popular', {'limit': '10'});
  final response = await http.get(url, headers: {
    'api-key': 'my_secret_key',
    'api-host': 'cookbookapi.example.com',
  });

  if (response.statusCode == 200) {
    List jsonData = json.decode(response.body);
    return jsonData.map((item) => Recipe.fromJson(item)).toList();
  } else {
    throw Exception('Failed to fetch recipes');
  }
}

class Recipe {
  final String title;
  Recipe({required this.title});

  factory Recipe.fromJson(Map<String, dynamic> json) {
    return Recipe(title: json['title']);
  }
}

Any suggestions on why RapidAPI might be failing would be greatly appreciated!

hey, i had similar issues w/ rapidapi. check ur base url and api key. sometimes, rapidapi has a different endpoint than expected. printing the response body may show error details. hope that helps!

Having worked extensively with RapidAPI, I can share some insights. One often overlooked aspect is the API’s rate limiting. RapidAPI frequently imposes strict limits on request frequency, which can cause intermittent failures. To mitigate this, implement a retry mechanism with exponential backoff.

Another common pitfall is SSL certificate validation. Some Flutter environments, especially on Android, can be overly strict. Try temporarily disabling certificate checks (not recommended for production) to isolate the issue:

HttpClient client = HttpClient()
  ..badCertificateCallback = ((X509Certificate cert, String host, int port) => true);

Lastly, ensure your RapidAPI subscription is active and you’re within your quota. The API might silently fail if you’ve exceeded your limits. Logging the full response, including headers, can provide valuable debugging information.

I’ve encountered similar issues when working with RapidAPI in Flutter. One common problem is incorrect header configuration. Make sure you’re using the correct headers for RapidAPI:

headers: {
  'X-RapidAPI-Key': 'your_rapidapi_key',
  'X-RapidAPI-Host': 'cookbookapi.example.com'
}

Also, double-check your API endpoint URL. RapidAPI often requires a specific base URL format. You might need to adjust your Uri.https() call accordingly.

If these don’t solve the issue, try adding error handling to your getRecipes() function to log the specific error message. This can provide more insight into what’s going wrong. Lastly, verify your API subscription status and usage limits on the RapidAPI dashboard.
