I would like to convert addresses into long/lat.

Althugh you asked for Google Maps API, I suggest an open source, working, legal, free and crowdsourced API by Open street maps
https://nominatim.openstreetmap.org/search?q=Mumbai&format=json
Here is the API documentation for reference.
Edit: It looks like there are discrepancies occasionally, at least in terms of postal codes, when compared to the Google Maps API, and the latter seems to be more accurate. This was the case when validating addresses in Canada with the Canada Post search service, however, it might be true for other countries too.
