In our Push-to-Deploy documentation we use the term Webhooks. But we didn’t quite explain what they are. Hopefully, if you’re using GIT you already know but we’re including this brief explanation just in case.
Let’s start with this image which shows a typical individual developer Workflow.
Now let’s walk through the steps in a bit more detail:
While it might not be fully obvious, one of the things you can do is configure your git provider to send web hook calls to multiple sites.
In other words, a single push to your main branch can trigger updates on 1, 2, 10 or 25 sites if all those webhooks are configured. Of course, if you actually do this, make sure your WPCD server is beefy enough to accept all those incoming connections at once. Otherwise your git provider will just register the webhook call as failed or timeout. (And some providers do have a hard limit on the number of webhooks you are allowed to configure.)
