What is GZIP compression and why should I use it?

GZIP compression is a file format used for file compression and decompression. The use of GZIP greatly reduces the size of data being transmitted, which helps lower data usage for some devices. It also helps to increase the speed of data requests. Examples of how to enable GZIP compression can be found on our Best Practices page.

Why is my location not available in some languages?

We make it a priority to make locations available in languages that are native to that area first, then add supplemental non-native language support if available. All locations are always available in English as a default option.

Why does the Auto Complete function of the Locations API not return my location?

Auto Complete works best for Latin based languages, and when 3 or more characters are entered into the search request. The more characters entered, the more accurate your results. Auto Complete returns the top 10 global locations, ordered by rank. Auto Complete does NOT work for postal codes.

Why do some Location keys end in “_AL”, “_PC”, or “_POI”?

“_AL” is a database code to denote an alias location. This means it is an alternative name for a location. A “_PC” code denotes a location key for a postal code. And a “_POI” code stands for a point of interest. More information about each Location type can be found here.

Can I hard code location keys or links from the API response into my code to reduce API calls?

Hard coding any information, such as location keys or links to our mobile or traditional sites, is strongly discouraged. Instead, we recommend using the data within the API response and consistently updating this information to ensure any potential updates or changes are seamlessly received by your product. This helps to prevent any “breaking changes” caused by AccuWeather updates to improve the end user experience.

Where can I find Air Quality and Pollen Forecasts?

This information can be found in the Daily Forecast API response, but only when “details=true” is properly appended onto the API URL. Please note that this content is currently only available for US locations.

Why are results not returned in both metric and imperial units in the Forecast API?

This is by design to help reduce payload sizes of the Daily and Hourly Forecast API responses. In addition to specific parameters, unit notations can also be found in forecast phrases. Therefore, returning both unit values in the Forecast response would require duplicating many parameters – which is not always preferred by developers. For this reason, to help reduce payload sizes and allow more developer options, units were separated to be more efficient for users only wishing to make use of one specific unit.

Is there a way to link to an extended daily forecast?

Yes. Links to our extended daily forecast are available at the beginning of our Daily Forecast API response, within the “Headline” section.
