OpenWeather API Key

API Key of the OpenWeather is stored in custom metadata that can be modify in the screenshot below:

Sample Apex Integration

On this method, named credentials is used to get the weather forecast from the OpenWeatherAPI.

private static final String OW_CURRENT_WEATHER_API = 'data/2.5/onecall?exclude=hourly,minutely,alerts';
private static final Integer DEFAULT_LATITUDE = 13;
private static final Integer DEFAULT_LONGITUDE = 122;
private static final String UNIT_METRIC = 'METRIC';

public static MW_OpenWeatherOneCall getWeatherForecast(Decimal longitude, Decimal latitude, String unitType) {
    MW_OpenWeatherOneCall weatherForecast = null;
    try {
        longitude = longitude == null ? DEFAULT_LONGITUDE : longitude;
        latitude = latitude == null ? DEFAULT_LATITUDE : latitude;
        unitType = unitType == null ? UNIT_METRIC : unitType;
        String endPoint = 'callout:Open_Weather_Service/' 
            + OW_CURRENT_WEATHER_API + '&lat=' + latitude + '&lon=' 
            + longitude + '&units=' + unitType + '&appId=' 
            + MW_UtilHelper.getOpenWeatherAPIKey();
        

        Http http = new Http();
        HttpRequest httpRequest = new HttpRequest();
        httpRequest.setEndpoint(endPoint);
        httpRequest.setMethod('GET');
        HttpResponse httpResponse = http.send(httpRequest);
        if (httpResponse.getStatusCode() == 200) {
            // Replace rain 1h attribute to oneHour
            String responseBody = httpResponse.getBody()
                .replace('1h', 'oneHour');
            weatherForecast = MW_OpenWeatherOneCall.parse(responseBody);
        }
    } catch (Exception ex) {
        System.debug(
                'Error : MW_OpenWeatherOneCallService.getWeatherForecast() with message ' +
                ex.getMessage()
        );
    }
    return weatherForecast;
}
