The Amazon SNS notification integration allows to process media asset updates in Webdam immediately, without manual interaction or delayed cron processes. See the Update Metadata page for more ways on how to update Metadata.
To set up notifications, first set up the event notification in the Webdam configuration. See the Webdam documentation for information on message types and information on how to set up the notifications.
Then enable the webdam_sns module. This will enable your Drupal Instance to receive the notification. The url for the notifications is: https://YOURSITE.com/_amazon-sns/notify.
Note that this URL can not be accessed in the browser, an error is the expected result.
See also the Amazon SNS Drupal project page.
A subscription must be configured for this Drupal installation on Amazon SNS, pointing to https://YOURSITE.COM/_amazon-sns/notify. Once set up the topic name should be logged on your site as part of the successful confirmation.
You can proceed to finish the configuration:
Go to the Webdam settings page.
Add the topic ARN in the field, Save.
Verify by making a change in Webdam on an existing asset that is used in your Drupal site.
