Use the Put Systems Manager Parameter action to persist event data

You can now use the Put Systems Manager Parameter action to persist event data from Bamboo notifications and tasks, Jira workflow transitions, and Jira Service Desk automation rule executions into the AWS Systems Manager (SSM) Parameter Store for use in subsequent automation workflows. This allows you to decouple the capturing of secrets and configuration data from Jira Service Desk request approvals, Jira issue edits or Bamboo plan executions from the decision to trigger subsequent automation by one or more target services:

AWS Systems Manager Parameter Store provides secure, hierarchical storage for configuration data management and secrets management. You can store data such as passwords, database strings, and license codes as parameter values. You can store values as plain text or encrypted data. You can then reference values by using the unique name that you specified when you created the parameter. [...] Parameter Store is offered at no additional charge.

Use CloudWatch Events to trigger notifications and actions for parameter updates

Using this action can in turn trigger notifications and actions via all other services that are supported targets in CloudWatch Events (this is an alternative to using the Put CloudWatch Events action directly).
