The WordPress app for Make has the following polling triggers:
Watch Categories – triggers when a new category is added
Watch Comments – triggers when a new comment is added
Watch Media Items – triggers when … you get the idea
Watch Posts
Watch Posts Updated – triggers when a post is updated
Watch Tags
Watch Users
Although these are polling triggers rather than Webhook triggers, Make’s scheduling feature means you can set them to poll as often as every minute (except for the Free plan, where it’s every 15 minutes). So it really depends on how “real time” your real-time need is.
If you absolutely need instant triggers, Make does also have an app to receive Webhook triggers from the WP Webhooks plugin – see Make’s help page on this.
We publish ~20 articles daily and we can’t poll – we need real-time actions when articles are published. And I mean REALTIME, not even with 5 or 10 or 15 minutes delay while polling.
