AccuMail Verify REST Service allows you to pass comma delimited files through the web to our secure SmartSoft cloud servers using basic REST POST methods. POST is a HTTP request that instructs the resource at the URI to do something with the provided entity. In the case of Verify REST Batch, the ‘entity’ is a comma delimited text file which contains several street addresses that require address standardization. The Verify REST Batch server retrieves the correct and coded results for each valid address and provides a URL and Token to download the updated list along with the CASS (3553) report.
