QuickSearch API: Features and Benefits in Detail
QuickSearch is a high-performance and scalable API based on up-to-date web and database technology. A major benefit of the API is that different data sources can be integrated and it can be adapted for the specific requirements of the customer. The API should leave nothing to be desired when searching for addresses.
Search the Way You Like
Enter your address or name in a search line and off you go.
With Typeahead, QuickSearch Understands Every Input Sequence
What do I have to enter first, the zip code or the city name or the street name or the house number? It doesn’t matter! QuickSearch understands every order thanks to the typeahead function. You are free to enter the information however you like and you will still get the right address. When using QuickSearch, simply enter the address you are looking for however it comes to mind.
Autocomplete: You Start, QuickSearch Completes It...
The API automatically suggests addresses and cities based on what you enter. QuickSearch works just like Google search. The important difference is that you can install QuickSearch in your IT infrastructure cost-effectively and in accordance with your internal confidentiality and data protection regulations. For the webservice solution, the data processing takes place securely in Austria and not outside the EU.
Efficient Data Acquisition and Always Correct Addresses
When entering addresses – for example when new customer addresses are created in a CRM – errors often occur. The addresses are incomplete, typing errors creep in and the addresses are saved in a different order. All of this leads to an unsightly mess of address data, which causes more trouble and frustration. If QuickSearch is integrated, this can never happen again.
- While typing their search, the user is provided with accurate mailing addresses that can simply be selected.
- The accurate mailing addresses are saved in your databases and assigned the correct XY coordinates.
- Making the address acquisition uniform across the different channels of your business (online, telephone, intranet, etc.) reduces errors and costs.
Address Data and Coordinates
QuickSearch not only provides correct addresses, but also coordinates. This is very convenient.
Up-to-date and Comprehensive Address Data for 70 Countries
Address data are available for 70 countries in Europe and America. WIGeoGIS optimizes the structure and content for the API, and in a further step integrates the data in the search database. The QuickSearch API is generally able to provide exact WGS 84 coordinates for street addresses. The address data is updated every year and is therefore always up to date.
