How to Use Slack Markdown in Salesforce Flow Builder

Slack formatting can be used when composing message text inside a Salesforce Flow’s Text Template, provided the output is sent to Slack via native Slack integration using Sales Cloud for Slack / Service Cloud for Slack / Salesforce for Slack.

• Use only Plain Text Mode in the Text Template.

• Do not use Rich Text Mode, as it will encode characters like *, _, and ~, breaking Slack formatting.

Steps to Add Slack-Formatted Text in Flow

1. Open your Flow in Salesforce and set the criteria as to when the flow needs to send the message to slack.

2. Add a Text Template element.

3. In the Text Template settings:

   • Set Body to the desired Slack message using correct Slack markdown (see table above).

   • Choose Plain Text format (important).

4. Save the template.

5. Use this Text Template in Send Slack Message Action

6. Test the message in a Slack channel to verify formatting (You can use debug in the flow to verify this configuration you will get the message in Slack, you don't need to activate the flow).

Tips for Usage

• Always preview complex messages before posting.

• Avoid using markdown syntax from other platforms (e.g., GitHub, Discord) as Slack’s parser differs.

• Use code blocks (```) for snippets or technical content to preserve spacing and formatting.

• Use inline code (`code`) for short identifiers, variable names, or commands.
