Slack Send V1.27.0

What's changed

This release introduces an optional payload-delimiter parameter for flattening nested objects with a customized delimiter before the payload is sent to Slack Workflow Builder when using workflow webhook triggers.

  - name: Send a custom flattened payload
    uses: slackapi/slack-github-action@v1.27.0
+   with:
+     payload-delimiter: "_"
    env:
      SLACK_WEBHOOK_URL: ${{ secrets.SLACK_WEBHOOK_URL }}

Setting this value to an underscore (_) is recommended when using nested inputs within Workflow Builder to match expected input formats of Workflow Builder, but the actual value can be changed to something else! This "flattening" behavior did exist prior to this version, but used a period (.) which is not valid for webook inputs in Workflow Builder.

Flattening example

The resulting output of flattened objects is not always clear, but the following can hopefully serve as a quick reference as well as these specs when using _ as the delimiter:

Input:

{
    "apples": "tree",
    "bananas": {
        "truthiness": true
    }
}

Output:

{
    "apples": "tree",
    "bananas_truthiness": "true"
}

Notice that bananas_truthiness is also stringified in this process, as part of updating values to match the expected inputs of Workflow Builder!
