This method takes a request, containing the desired Place’s reference value.If only they told you how to get the value…ugh… After playing around with it, I found that the textSearch() method included this value in its response. I put together a client side script that uses a jQuery geocomplete plugin to get the lat/lng to pass the textSearch() method to retrieve the Reference String. You only need to know the address of place you are searching for.
I am not going to provide the script for it, but if you view source you can pull the appropriate code. ——> Find Google Places Reference String Now
