It’s worth noting @sergi0fores, since posting this question I’ve developed a plugin that does just that, integrates ACF data into WP-API automatically.
You can download the plugin here: https://wordpress.org/plugins/acf-to-wp-api/
I use this every day with AngularJS, and it makes for a great setup.
Yep, that’s the one! I’ve attached a screenshot of the option, just to clarify.
Thanks,
Chris
