This question runs in a pre-configured Salesforce environment - no personal connection required.
Create a method that provides weather-based recommendations for cities by integrating with OpenWeatherMap APIs. Your solution will demonstrate advanced integration patterns by chaining multiple API calls and handling complex data transformations.
Your method should:
- Validate input (return "Invalid city name" for null/empty)
- Call geocoding API to get coordinates
- Call weather API to get current conditions
- Convert temperature from Kelvin to Celsius
- Return temperature-based recommendation:
-
25°C: "Hot"
- 15-25°C: "Warm"
- 5-15°C: "Cool"
- <= 5°C: "Cold"
-
Handle all API errors gracefully by returning appropriate error messages.
