Approval of a PR made by another action

[freearhey]

Is it possible to run this action right after another action has created a pull request?

Neither push event nor pull_request in my case trigger this action.

At the same time, it’s also not very clear how to correctly filter PR made by an action. Should it be if: github.actor == 'github-action' or if: github.actor == 'github-action[bot]' or something else?

I don't think that's possible. From https://help.github.com/en/articles/events-that-trigger-workflows#about-workflow-events:

An action in a workflow run can't trigger a new workflow run. For example, if an action pushes code using the repository's GITHUB_TOKEN, a new workflow will not run even when the repository contains a workflow configured to run when push events occur.

I assume this is to prevent infinite chains of actions being triggered.

Thanks for the answer!

Now that Github Actions has the workflow_dispatch event, I think it is possible to trigger one workflow from another. So I would love it if this action took an optional input for the pull request number, because then it can be used from a workflow that executes on the workflow_dispatch event.

I know I can't reopen this issue, but I did create a pull request to implement the functionality I want here, if you're interested.
