The Advanced Custom Fields integration enables you to automate processes on your WordPress site when using Advanced Custom Fields for custom functionality.
Trigger: A field is updated on a post
This trigger fires whenever an ACF field is updated on a specific post, or all posts of a specific type.
When selecting all posts of a specific type, all ACF fields defined for posts of that type are available for selection. When selecting a specific post, the available fields are narrowed further based on the fields available in that specific post.
Note: This trigger will only fire when an existing value is changed. When the first value is populated into an empty field, the trigger does not fire, as ACF does not call the same hook.
More triggers and deeper integration are in the works, so stay tuned!
