Slack Web API Action

Slack Web API wrapped in Github Action.

Setup

Action requires slack bot token - follow this instruction to get one.

Usage

Send a simple text message to a channel.

- name: Simple Slack message                    
  uses: stopa323/slack-web-client@v1.0
  with:
    slackToken: ${{ secrets.SLACK_BOT_TOKEN }}
    slackMethodArgs: |
      {
        "channel": "pkw",
        "text": "Cos sie... cos sie popsulo..."
      }

The slackMethodArgs parameter expects a string in the JSON format.

The slackAPIMethod parameter can be used to change default api method chat.postMessage to any supported by the @slack/web-api package:

- name: Update message                   
  uses: stopa323/slack-web-client@v1.0
  with:
    slackToken: ${{ secrets.SLACK_BOT_TOKEN }}
    slackAPIMethod: chat.update
    slackMethodArgs: |
      {
        "channel": "pkw",
        "ts": "0123456789.000000",
        "text": "Powtarzam jeszcze raz"
      }

Action results can be accessed via slackMethodResults output:

jobs:
  createSlackMessage:
    name: Create CI status Slack message
    runs-on: ubuntu-latest
    outputs:
      slackMessageTs: ${{ fromJson(steps.create_message.outputs.slackMethodResults).ts }}
    steps:
      - name: Create message
        uses: stopa323/slack-web-client@v1.0
        id: create_message
        with:
          slackToken: ${{ secrets.SLACK_BOT_TOKEN }}
          slackMethodArgs: |
            {
              "channel": "ci",
              "text": "Build #2137 started..."
            }
  runTests:
    name: Run pytest
    runs-on: ubuntu-latest
    needs: createSlackMessage
    steps:
      ...
      - name: Update message with status
        uses: stopa323/slack-web-client@v1.0
        with:
          slackToken: ${{ secrets.SLACK_BOT_TOKEN }}
          slackAPIMethod: chat.update
          slackMethodArgs: |
            {
              "channel": "C01667Y1K8U",
              "ts": "${{ needs.createSlackMessage.outputs.slackMessageTs }}",
              "text": "Build #2137 failed"
            }
