Subject: Script to collect CSV notification status responses
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=af56c5c5cf0fde61544175edbf901b5313498ea2;p=evergreen%2Fmasslnc.git

Script to collect CSV notification status responses

For 3rd-party services which provide batch notifications status updates
via CSV file.  The script assumes the action/trigger event definition ID
is included in the response and, from there, applyes the "status" value
to the async_output of the event definition in question.
