Hi @jackherizsmith, unfortunately, Slack's mrkdwn does not natively support markdown's list sytanx. As a workaround, you need to • item 1\n• item 2\n• item 3 or something like that. Also, we don't tell whether any enhancements regarding this can come in the future. I know the answer here is not great for you, but I hope this helps clarify.

That's very helpful clarification - so assuming the more advanced <@U[SLACK_ID]> also won't work?

[jackherizsmith]

is there an alternative you can recommend, in order to get this formatting to work from a GitHub action?

[jackherizsmith]

I suppose rather than using this action, I could write a custom step that invokes curl?

[seratch]

The list syntax just does not exist. Any other syntax available here should work when using this GitHub action library. Please refer to https://github.com/slackapi/slack-github-action/tree/main/example-workflows too.

ah I see interesting! so lists (bullet points) are specifically broken, and everything else should work as documented?

I'm using Technique 1: Slack Workflow Builder and not observing any formatting to work. That doc link says:

You can select where you want to post the data and how you want to format it in Slack's workflow builder interface.

but the Workflow Builder modal doesn't let me do much with the "variables" (e.g. can't use them in links or code fences). It seems to let me bold-face or italicize a "variable":

but even that doesn't work; everything is rendered without formatting:

Example GHA run:

Run slackapi/slack-github-action@v1.24.0
  with:
    payload: {
    "text": "Sample text, *bold1* **bold2** _italic_ `code` [link](https://github.com/slackapi/slack-github-action)\n```code fence```\n"
  }
  
  env:
    SLACK_WEBHOOK_URL: ***

@seratch when you said:

Any other syntax available here should work when using this GitHub action library.

is that supposed to apply to "Technique 1"?

@ryan-williams

is that supposed to apply to "Technique 1"?

No, any of Slack syntax does not work in Workflow Builder variables. I should have been more specific, but I meant, as long as you use incoming webhooks or chat.postMessage API to directly post a Slack message from your GitHub Actions job, any formatting syntax are available for it while they are not available for Workflow Builder integration.

@jackherizsmith Sorry for my late response here:

so lists (bullet points) are specifically broken, and everything else should work as documented?

All the syntax documented work as you expect.

Let me close this issue now 👋
