The Slack Orb comes with a number of included templates to get your started with minimal setup. Feel free to use an included template or create your own.

	success_tagged_deploy_1	To be used in the event of a successful deployment job. see orb usage examples
	basic_on_hold_1	To be used in the on-hold job. see orb usage examples

Custom Message Template

1. Open the Slack Block Kit Builder: https://app.slack.com/block-kit-builder/
2. Design your desired notification message.
3. Replace any placeholder values with $ENV environment variable strings.
4. Set the resulting code as the value for your custom parameter.

- slack/notify:
    event: always
    custom: |
      {
        "blocks": [
          {
            "type": "section",
            "fields": [
              {
                "type": "plain_text",
                "text": "*This is a text notification*",
                "emoji": true
              }
            ]
          }
        ]
      }

Branch or Tag Filtering

Limit Slack notifications to particular branches with the "branch_pattern" or "tag_pattern" parameter.

A comma separated list of regex matchable branch or tag names. Notifications will only be sent if sent from a job from these branches/tags. By default ".+" will be used to match all branches/tags. Pattern must match the full string, no partial matches. Keep in mind that "branch_pattern" and "tag_pattern" are mutually exclusive.

See usage examples.

Thread Messages

Post replies in threads with a special parameter thread_id. Including this parameter in the notify command reference stores the id of the message in a small portion of bytes in cache. Any subsequent invocation of the command with the same value for thread_id will post a reply to the initial message in a thread. Example:

- slack/notify:
      event: always
      channel: engineering
      thread_id: testing
      custom: |
        {
          "blocks": [
            {
              "type": "section",
              "fields": [
                {
                  "type": "plain_text",
                  "text": "*Tests started.*",
                  "emoji": true
                }
              ]
            }
          ]
        }
- slack/notify:
      event: always
      channel: engineering
      thread_id: testing
      custom: |
        {
          "blocks": [
            {
              "type": "section",
              "fields": [
                {
                  "type": "plain_text",
                  "text": "*Tests finished.*",
                  "emoji": true
                }
              ]
            }
          ]
        }
