Technique 1: Slack Workflow Builder
📝 This technique uses Workflow Builder, which requires a Slack paid plan.
This technique sends data to Slack using a webhook to start a workflow created using Slack Workflow Builder.
Setup
The Slack app manifest included with each example showcases steps of a workflow in Workflow Builder along with the webhook trigger inputs.
For details on how to setup this technique in GitHub Actions, read the
README.md.
Example workflows
- Format generated files: Message outputs from prior steps.
- Post release announcements: Share releases to a channel.
- Update a channel topic: Highlight the current build status.
Format generated files
