Making Flow Designer Slack Notifications More Maintainable

Hi everyone,

 

I’m looking for advice on improving how we send Slack notifications from Flow Designer.

 

Current setup

  • We use the Flow Designer “Slack Webhooks” action “Post a message” to send notifications to specific channels.

Problem

  • It’s not clear which flow or event produced a message unless you open the flow itself.

What I want to do (developer-first)

  • I’d like to make messages template-driven (similar to ServiceNow notifications) or include clear metadata so that when a developer needs to modify a notification, they can immediately tell which flow/action/template to edit.

Questions

  • Does anyone have recommendations or best practices for doing this with Flow Designer + Slack Webhooks?
  • Are there existing patterns, plugins, or integrations that make notifications more maintainable (e.g., centralized templates, variables, or a registry of notification templates)?
  • Sample message formats or examples would be especially helpful.


Cheers,

Hi @777_ ,

I followed this article to post messages from servicenow flowdesigner to slack.

https://www.servicenow.com/community/developer-forum/servicenow-slack-integration/td-p/2875332

Plugin: We need to enable ServiceNow IntegrationHub Installer plugin.

Thank you @PoonkodiS .

 

I’m currently sending messages from Flow Designer the same way you suggested.

 

However, the drawback of this approach is that if I want to modify a message, I have to open the flow in Flow Designer and inspect the action’s inputs to view the message, which I find inconvenient.

For that reason, I’m wondering whether it’s possible to manage messages centrally (for example in a table), similar to Email templates [sysevent_email_template] or Notifications [sys_notification].

 

If this can be done, I would appreciate any guidance. For Slack-related plugins, we’ve already installed “Slack Webhooks Spoke for ServiceNow IntegrationHub”.

 

Thank you in advance.
