Address Web Service


The Address Web Service allows developers to search, validate and geocode against the Johnson County master address database. A security key is required for some of the methods if you are doing more than 1,000 requests per day. To obtain a security key, please contact [email protected]. Once an address is found, you can lookup the tax property ID and its tax unit. There are also methods to give you all the valid cities, zip codes, street types, street directions, unit designators, and street names used in the county.

As a web service, an application developer can utilize the master address database even when they are not on the county network. Web services are built on SOAP, so any language that can understand SOAP can be used to access the Address Web Service. AIMS has tested languages like .NET languages, Java, VB6 and VBA. With the right toolkit, all these languages and more can use the web service.

Excel Spreedsheet Example

You can use the Address Web Service in many different environments. In this example, we'll show that even an Microsoft Office document can take advantage of the web service.
Figure 1. Excel Sample
Figure 1. Excel Sample

Figure 1 shows a simple Microsoft Excel that you can enter an address and validate it. If the user were to type an address in cell B1 and press the "Validate Address" button, VBA code can send the address to the web service and get a list of matching addresses to the one entered as seen below.

.NET and Java can produce the same results. As long as you have a programming language that can communicate to a web service, you could use the Address Web Service to validate addresses in Johnson County.
