Launching Google Maps and performing a specific action If api=1 is NOT present in the URL, all parameters are ignored and the default Google Maps app will launch, either in a browser or the Google Maps mobile app, depending on the platform in use (for example, https://www.google.com/maps).

URL Encoding (Percent Encoding) URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.

If you use a pipe character ( | ) as a separator, be sure to encode the pipe as %7C . A comma in a string should be encoded as %2C . It is recommended you use your platform's normal URL building libraries to automatically encode your URLs, to ensure the URLs are properly escaped for your platform.
