Postback URL: Real Time and Offline
Scan records can be posted directly to your servers or third party servers. They can be posted in real time if the app has Internet connectivity (online) and on upload from the app when it gets connectivity if temporarily offline. This feature can be used for validation services and for record-only services.
Postback in real time is enabled by selecting ‘Redirect Scans to a Third Party Server’ on the first tab when creating a service. This option is primarily meant for scan records you want posted directly to and from the app to your server, called Direct Scan to URL (DSU).
More common, however, is a simple Postback URL selected on the Advanced tab when creating a service. In this case scan records post to our server first and then yours, with or without a return response to the app from your server. Enabling postback here gives you many more options, including the ability to select an Export Template to determine what data gets posted and the ability to post scan records captured offline (Postback on upload).
