Sending techniques

This GitHub Action offers three different techniques to send data to Slack:

• Send data with a webhook to start a workflow in Workflow Builder.
• Send data using a Slack API method and a secret token with required scopes.
• Send data as a message with a Slack incoming webhook URL.

Expected outputs

Each technique above outputs values that can be used as inputs in following steps of a GitHub workflow.

The following outputs are returned with each of the techniques:

Output	Type	Description
time	number	The Unix epoch time that the step completed.
ok	boolean	If the request completed with success.
response	string	The response from the request as stringified JSON.

While these outputs are returned with certain Slack API methods:

Output	Type	Description
channel_id	string	The channel ID included in the response.
ts	string	The timestamp of the Slack event or message.
thread_ts	string	The timestamp of a parent Slack message with threaded replies.

Example responses

The following snippet shows how multiple steps can be chained together to create a Slack channel before posting a message:

- name: Create a new Slack channel for recent changes
  id: conversation
  uses: slackapi/slack-github-action@v2.0.0
  with:
    method: conversations.create
    token: ${{ secrets.SLACK_BOT_TOKEN }}
    payload: |
      name: pull-request-review-${{ github.sha }}
- name: Send the pull request link into the Slack channel
  if: ${{ steps.conversation.outputs.ok }}
  uses: slackapi/slack-github-action@v2.0.0
  with:
    method: chat.postMessage
    token: ${{ secrets.SLACK_BOT_TOKEN }}
    payload: |
      channel: ${{ steps.conversation.outputs.channel_id }}
      text: "A PR was created <!date^${{ steps.conversation.outputs.time }}^{date_num} at {time_secs}|just now>: ${{ github.event.pull_request.html_url }}"
