Why this helps
Reviewers lose time opening preview links and orienting themselves before they can assess a change.
- Create a visual artifact when a new pull request arrives.
- Make preview review easier to pick up between other tasks.
- Send the screenshot result to a chosen run report channel.
Setup
Build it in a few focused steps.
- 1Connect GitHub and Browserless once in the Notis portal.
- 2Create an automation in the portal or tell Notis from any channel.
- 3In one instruction, ask Notis to capture a screenshot of the new pull request's preview page when a usable preview URL is available.
- 4Pick the New Pull Request Created trigger.
- 5Choose a report channel, then test with one real pull request that has a preview URL.
Questions about this workflow
Will this create a preview deployment?
No. It captures a screenshot from a preview URL that already exists and is available to the automation.
What if the pull request has no preview URL?
The automation needs a usable URL. If the event context does not provide one, include how Notis can obtain it in your instruction.
