how to find weather forecast city id?

Question

final String FORECAST_BASE_URL =
        "http://api.openweathermap.org/data/2.5/forecast/daily?";
final String QUERY_PARAM = "q";

Hello. I'm making a weather forecast app. But when I use "http://openweathermap.org"'s API, I stock in trouble how can I get the city code or ID "q"? I try to find the city ID but I can't.

Example code Call by city ID:

api.openweathermap.org/data/2.5/forecast/daily?id=524901

and I heard that "q" is used to "id" also. I mean

api.openweathermap.org/data/2.5/forecast/daily?q=524901

is also possible. i want to do like this.

So, How to find city id? Anybody knows?

Answer 1

There is a similar question that was asked in the OpenWeatherMap support center. Here is the link OpenWeatherMap

Also, here is a link to the list of cities and their respective ID's (just CTRL + F to find the city you want): List of Cities & IDs

Answer 2

A full list of CityID's can be downloaded from: http://bulk.openweathermap.org/sample/city.list.json.gz

You can manually search that file (after unzipping it) for your city name or search from the shell like:

grep -i "london" city.list.json

Regarding the "q" vs. "id" query tags: you can search by city (and country) using the "q" tag like this:

http://api.openweathermap.org/data/2.5/forecast/daily?q=London,GB

(note that the country code isn't necessarily required)

and that works as long as there is no question about which city. If there's multiple cities of the same name in a country, though, you can use the CityID to specify a certain one after you've found the correct identifier in the list linked above like this:

http://api.openweathermap.org/data/2.5/forecast/daily?id=2643743

which also returns London's weather, but ensures you don't accidentally get the weather for London, Kentucky, USA or London, Ohio, USA if you've chosen not to use the country code in the "q" tag.
