Configure AWS SNS for CSM
Simple Notification Service (SNS) sends messages to CSM webhooks to enable key features in the AWS mApp® Solution.
You need a minimum of two topics for this mApp Solution, one for each webhook in the system.
To configure AWS SNS for CSM:
- In the AWS console, navigate to https://console.aws.amazon.com/sns/.
Update the Cherwell CMDB
-
Webhook passwords should not correspond to any CSM logins. Instead, they are arbitrary and used for the webhook only to enhance security.If you have not already done so, in CSM Administrator, go to and set a custom webhook username and password for the AWS webhooks that were provided with the mApp Solution.
- Copy the Full Endpoint from the General
page of the Webhook Manager. Using the new username and
password you just set for the webhook, modify the copied URL to fit the
following format (replace the sample information for webhook username and
password, as well as the external URL of your CSM server):
https://webhookUsername:[email protected]/CherwellAPI/api/Webhooks/createawsconfigstaging
- Copy the Full Endpoint from the General
page of the Webhook Manager. Using the new username and
password you just set for the webhook, modify the copied URL to fit the
following format (replace the sample information for webhook username and
password, as well as the external URL of your CSM server):
- To create a topic for the AWS Create Config Staging webhook, see Creating an Amazon SNS Topic. You do not need to complete any of the optional steps for the mApp Solution to work properly. In our examples, the topic was named 'update-cherwell-cmdb' and will use that for our guide.
- To create a subscription for the AWS Create Config Staging webhook, see
Subscribing to an Amazon SNS Topic. Use
the following information:
- Topic ARN: Select update-cherwell-cmdb.
- Protocol: HTTPS
- Endpoint: Enter the modified URL from your database.
