The POST request enables you to submit a single input address or a list of addresses for batch processing. Matching and/or geocoding preferences can optionally be specified to the Geocode service and receive the associated latitude/longitude coordinates and location information. The preference options for a POST request are the complete set of available options.
The GET request enables you to submit an input address and matching and/or geocoding preferences to the Geocode service and receive a response that provides the candidates object which contains the associated latitude/longitude coordinates and other matching and location information about each candidate. The preferences for a GET request are a subset of the total available with the POST request. Each key/value pair is separated by an ampersand (&).
