PostData Shell Properties

The PostData Shell property is available if the script is accessed via "ScriptPage" (URL Direct Access Context), and if the Content Type passed to the URL is "application/json", and if the HTTP call is a POST. The included POST data will be available via PostData.

Shell.PostData()

string (output). The POST data from the HTTP call.

You can use an HTTP POST to send JSON data to your script in the URL Direct Access Context. The POST body of the HTTP message is added as a string-Variant to the shell object with Shell.PostData to provide the body.

First, note the following requirements:

• To protect from data overflow, this is limited to HTTP requests with a body of size X, where X is controlled by an entry in the TS_SYSTEMSETTINGS table named "ScriptPostDataMax" (otherwise, the default value is 10485760 bytes). If this value is not present in TS_SYSTEMSETTINGS, you can add it manually by following the steps described here.
• The request must be a POST (not a PUT, etc.)
• The HTTP header for the request must have a "Content-Type" of "application/json".

SBM AppScript does not have any built-in tools for parsing JSON data, but the Shell.PostData should be available if all these criteria are true.
