GitHub Actions get from API to create pull request

Question

Is there a way to tell GitHub to automatically create a pull request from an API providing JSON content and merge it into my project?

I want to:

Edit files on a platform (I control the platform) using my own production editors/tools.
Have GitHub request it (REST), then create a PR or a commit, so people can collaborate on it with forks/GitHub project management.
Push from GitHub back to the platform for publishing.

3 is no problem, but 2 I can't find documentation for if it's even possible.

github needs an action to trigger the github-action run - dozens of actions are supported so maybe as part of (1) you could update something on the github repo or you could run the action on a schedule (docs.github.com/en/actions/using-workflows/…) - you could try github.com/marketplace/actions/http-request-action for the REST bit (2) - then github.com/marketplace/actions/create-pull-request for the PR (2) — PJ Fanning

@PJFanning I see thanks, so either a schedule or do something arbitrary to trigger the action, like creating a new issue? Then the actions can create the PR. Is it just the PR or is it capable of creating the new files the PR requires? That can all be done through the actions? If so go ahead and leave the answer and I will give it to you. — Harry

Okay after a lot more poking now I understand how this works. The Github documentation doesn't cover anything because the default actions are extremely limited. Instead there's a marketplace of actions that has the functionality I need, including httpr, create file, create PR. You string them together to do this. Actions can be triggered manually as well as on a timer so that's fine. Thanks to @PJFanning putting me in the right direction. — Harry
